She liked him, though. He had no doubts about that. She’d even given him a second blowjob recently, though he’d cum even quicker than the first time.</p><p>“So, where are we going, exactly?” Derek asked as he turned to face the vast expanse of trees they were about to walk into.</p><p>“There’s a trail,” Anna answered. “The spot we’re headed to is half a mile from here. It’s right by the river. There’s a tree that hangs out over it that we all use a little like a diving board. There’s a rope swing, too, though it’s been there forever and sometimes it seems like it could snap if someone tugged too hard on it.”</p><p>Derek got a good grip on the cooler and Anna locked the car as they headed off into the woods to join her friends for the afternoon. “You look really good in that bikini, by the way,” he noted while taking a moment to admire Anna’s perky breasts in the yellow bikini top she had on.</p><p>She smiled and said, “It’s a thong bottom.”</p><p>Derek felt a gentle stirring between his legs at the idea of seeing Anna in something so skimpy and sexy.</p><p>“Would you like to see it?” she asked.</p><p>“I would,” Derek replied with a nod.</p><p>Anna unbuttoned her shorts, spun around, and pulled them down. Her ass looked breathtaking with the thin yellow strip of fabric running down the crack.</p><p>“Wow, Anna, you look amazing,” he said. “You look hot.”</p><p>Anna stepped out of her shorts and set them on the top of the cooler. “There’s no reason to keep my shorts on then, is there? I suppose I should walk ahead of you, shouldn’t I? A good girlfriend would let her boyfriend stare at her ass, wouldn’t she?”</p><p>“I’d certainly enjoy that,” Derek said.</p><p>Anna smiled and walked out ahead of them, offering the view she’d promised. Derek kept his eyes on her ass for their entire stroll through the woods and it felt like his excitement built with each step. He was certain Anna was putting a little extra sway in her hips, too, no doubt to be even more appealing to him.</p><p>“We’re almost there,” Anna said as a delighted scream rang out, no doubt signaling that someone had just taken the plunge into the chilly waters of the river. Derek nearly bumped into Anna as she stopped in the middle of the trail. “Put the cooler down,” she instructed.</p><p>Derek did so and Anna pressed her lithe body against his. They kissed and she grabbed his hands and placed them on her ass while their tongues danced. Derek was hard in an instant and when Anna moaned into his mouth his cock grew even harder.</p><p>“On your knees,” Anna said softly.</p><p>Derek fell to his knees and looked up at her. Anna smiled, slowly spun around, and pulled aside her thong bottom.</p><p>“Kiss it,” she instructed.</p><p>Derek’s heart pounded as he leaned forward and pressed his face between his girlfriend’s taut ass cheeks. His lips found her asshole and he kissed it while holding his tongue despite his desire to lick her.</p><p>“Now lick it,” she said, filling him with delight.</p><p>Anna moaned as Derek licked her asshole. His cock throbbed from doing something so naughty in a location where one of her friends could easily find them. Derek suspected Anna didn’t care about that, though. Melanie had already witnessed him eating her pussy, after all, and she seemed delighted about it.</p><p>“Very good,” Anna said as she stepped away, pulled her thong back into place, and helped Derek to his feet. “That’s quite the boner you’ve got there. Did it excite you to eat my ass?”</p><p>“It did,” Derek replied. “Is that bad?”</p><p>Anna smiled and shook her head. “Not at all. Now pick up the cooler and let’s go have some fun.”</p><p>Derek did as instructed and they reached Anna’s friends in just a few minutes. Most of the faces were familiar from the beach party and Anna happily introduced him to those he didn’t know, with the exception of a particularly good-looking guy who already had his shirt off and boasted a rather muscular body.</p><p>“I don’t know you,” Anna said.</p><p>“This is Cooper,” Melanie replied. “He’s an old friend of mine. He’s in town for a few weeks so I thought I’d bring him. Cooper, this is Anna, the girl I was telling you about.”</p><p>Cooper extended his hand and smiled as Anna took it. “It’s a pleasure to meet you, Anna.”</p><p>“Melanie told you about me, huh? I hope she only said nice things,” Anna replied.</p><p>It seemed to Derek that Melanie had brought her hunky friend with the intention of introducing him to Anna, who seemed to be taking the bait, at least based on the smile on her face and the way she seemed to lean towards Cooper, as if her body couldn’t help but want to be near him.</p><p>“This is Anna’s boyfriend, Derek,” Melanie said.</p><p>Cooper looked Derek up and down, smiled in a surprisingly confident way, and said, “It’s nice to meet you, Derek.”</p><p>The handshake proved painful for Derek as Cooper seemingly tried to crush his bones into dust. He did his best not to show it, but it hurt enough that Derek was certain it showed on his face.</p><p>“No one’s been brave enough to try the rope swing yet,” Cooper said as he turned his attention back to Anna. “But Melanie tells me you’re always up for it. Is she right?”</p><p>Anna laughed in a decidedly flirty manner and replied, “She is. It’s not like it’s ever broken. I don’t understand why everyone else is such a chickenshit about it.”</p><p>“The rest of us are scared about falling into the dirt or cracking our heads open on one of the rocks by the shore,” Melanie said.</p><p>“Well, I’d love to hit the rope swing,” Cooper said. “Are you up for it, Anna?”</p><p>“I am,” she replied.</p><p>“How about you, Derek?” Cooper asked. “You wanna go for a swing?”</p><p>Derek knew he was being challenged, and yet he was far more nervous about making a complete fool of himself by falling to the ground or getting tangled up in the rope, so he passed up the chance to join them. “No, I’m good,” he said.</p><p>Cooper smiled, turned to Anna, and said, “Very well then. It’s just the two of us.” He deftly put an arm around her waist and they walked towards the river and the thick tree branch around which the rope swing was tied.</p><p>“I hope you don’t mind that I brought Cooper along,” Melanie said as she approached Derek.</p><p>He watched Cooper’s hand move a little bit lower until his fingers were resting just above the fabric of Anna’s bikini bottoms. Just a few more inches and he’d be groping her bare ass cheek. Derek knew Anna would move Cooper’s hand if she didn’t want him touching her there – she wasn’t the sort of girl to let a guy do anything she wasn’t interested in – so the fact that she didn’t meant she’d already warmed up to the idea of receiving a little affection from him.</p><p>“I’m not sure what I think,” Derek said, both as an answer to Melanie and as a vocalization of the confusing thoughts dancing through his head.</p><p>“Would you like to know what I think?” Melanie asked.</p><p>“Sure,” Derek replied as Cooper reached for the rope swing and handed it to Anna. He stepped behind her as she took a tight grip and he found a reason to put both his hands on her waist and press his body against hers, presumably under the guise of helping her get ready to take the plunge into the cool, relatively slow-moving waters of the river.</p><p>“I think Cooper’s perfect for her,” Melanie said. “I think Anna’s been missing what Steve gave her – and what you apparently can’t give her – and I’m fairly certain Cooper can give her that.”</p><p>“If that’s true, why didn’t you take him for yourself?” Derek asked.</p><p>“We’ve known each other for 15 years. Hooking up with him would be like hooking up with my brother,” she explained. “I don’t mind him hooking up with a good friend of mine, though.”</p><p>Cooper stepped back and Anna lifted her feet off the ground and swung out over the river. She let go of the rope, dropped into the cool water, and disappeared for a moment before surfacing and pushing her hair out of her face. She screamed in delight as the rope swung back to Cooper. He grabbed it with both hands and swung out just like Anna had. He dropped into the water right next to her and when he surfaced he did so mere inches from her.</p><p>“You can tell that she wants him, can’t you?” Melanie asked.</p><p>Derek didn’t know Melanie well enough to understand what she was doing, so he wasn’t sure he wanted to engage in much conversation with her. For that reason, he chose not to answer.</p><p>Anna emerged from the water first and Cooper followed. She rushed up the bank of the river and grabbed the rope once more. Before Cooper could reach her Anna was swinging again. She dropped into the water and he soon followed. This time he emerged from the water behind her and seemingly pressed his body against hers. Derek couldn’t see perfectly from his position, but he was certain that Cooper kissed the back of Anna’s neck a few times, bringing a smile to her face.</p><p>“Look at that. They’re already getting a little bit frisky for each other,” Melanie said, confirming Derek’s suspicions that his girlfriend and another guy were doing a little bit of fooling around in the water.</p><p>Derek was a little surprised that a touch of arousal mixed with the jealousy coursing through him.</p><p>“You’re not going to do anything?” Melanie asked.</p><p>Derek finally turned to look at her and saw a bright smile on her face. “What do you mean?”</p><p>“She’s your girlfriend, Derek,” Melanie said. “Most guys wouldn’t be okay with their girlfriend fooling around with someone else right in front of them.”</p><p>“I know it’s weird,” Derek replied. “But I guess I’m just weird.”</p><p>Melanie stepped close enough that their arms touched. “There’s nothing wrong with being weird,” she said. “Weird can be fun. It seemed like you were having fun in Anna’s truck a few days ago, for instance.”</p><p>Melanie’s fingers moved over the back of Derek’s hand and he felt a surprising rush of pleasure at her touch. Combined with the look on her face, it seemed like she was expressing desire and Derek couldn’t help but feel lured in by it. For a moment he considered taking her hand and seeing what she would do, but the moment passed quickly as Derek remembered what Anna had said. She was allowed to play, but if he wanted to be with her, she was the only one he got to play with.</p><p>Derek stepped away from Melanie and said, “Sorry. I can’t.”</p><p>Melanie made a playfully sad face and replied, “Well, if you ever decide that you can, let me know. I think we could have a lot of fun.”</p><p>She reached back and grabbed Derek’s ass through his swimsuit, nearly causing him to cry out from the sheer surprise of it. Melanie winked at him and walked away as he turned his attention to the river. A few of Anna’s friends had joined her and Cooper in taking turns on the rope swing and still others were headed for the remarkably thick branch that stretched out over the river. Derek felt foolish standing around and watching, so he headed over and joined in on the fun.</p><p>Anna’s friends were just as welcoming as they’d been at the bonfire, if not more so. For that reason, Derek ended up having a great time. He even took a few turns on the rope swing and, much to his surprise, didn’t come close to making a fool of himself.</p><p>Derek was having such a good time that he didn’t notice that Anna and Cooper had, at some point, disappeared. Anna’s yellow bikini was hard to miss, but a quick scan of the area surrounding their little gathering revealed nothing.</p><p>“They took off ten minutes ago,” Melanie said as she sidled up next to Derek. “I thought for sure that Anna would be able to wait until later, but I guess I was wrong. It seems like she really needs what Cooper can give her.”</p><p>Derek was a little annoyed that Anna couldn’t have waited. It seemed unfair of her to make it so obvious that she was fooling around with someone else. Melanie was the only one who’d mentioned it, but Anna’s other friends had almost certainly noticed – or would notice at some point – and Derek couldn’t help but feel a little embarrassed.</p><p>“You know, I’d be happy to take you off into the woods,” Melanie said. “I’d lean up against a tree and let you have a little fun with my body. You could play with my tits and get on your knees and eat my pussy until I cum. Anna says you love eating pussy, and she’s clearly busy right now, so why don’t you come with me and do what you love? I might even be willing to make you feel good, Derek. Who knows, maybe if you’re really good at eating pussy I’ll bend over and let you have a go at me. Wouldn’t that be fun?”</p><p>Derek thought about taking Melanie up on her offer, but a moment later a wave of guilt washed over him. He felt so weak for even being tempted by her. They didn’t know each other at all, which meant there was no chance she was actually into him. Whatever was going on with her didn’t have anything to do with Derek.</p><p>“Being with Anna can be frustrating,” he said. “Like right now. But it’s also exciting. Again, I know it’s weird, but I don’t really care about that. When I’m frustrated I tend to forget just how much I like her – like, really like her – and I can’t imagine throwing that away just to fool around in the woods.”</p><p>“You were tempted though, weren’t you?” Melanie asked with a devilish smile on her face.</p><p>Derek laughed. “You’re very tempting. But, I really just want to be with Anna.”</p><p>“Even if she wants to be with other guys?” Melanie said. “Because you know she’s almost certainly getting fucked right now, right?”</p><p>Derek nodded.</p><p>“Anna was right about how loyal you are,” Melanie said. “I think she’s taking advantage of you, but you seem to think that being with her is the most exciting thing in the world, so I guess I’m wrong.”</p><p>Melanie gave him a quick kiss on the cheek and walked away as Derek pondered what she’d said. Was Anna taking advantage of him? He didn’t think so. He knew what he was getting into with her. She’d been up front from the start. Even when she decided she was his girlfriend Anna had been clear that it was unlikely Derek would fuck her. She’d been clear that she would find another guy after Steve, too. She wasn’t taking advantage, and Derek was having a hell of a lot of fun. Plus, Anna was responsible for showing Derek pleasures unlike any he’d ever experienced in his life.</p><p>The sound of crunching leaves caught Derek’s attention and he turned to see Anna and Cooper coming out of the woods. They stopped at the edge of the clearing and shared a remarkably long kiss before Cooper continued towards the river while Anna remained at the wood’s edge. She beckoned for Derek to approach and he did so without hesitation.</p><p>“Did you miss me?” Anna asked.</p><p>“I did,” Derek replied.</p><p>“Did Melanie try and flirt with you again?” she asked.</p><p>Derek nodded.</p><p>Anna stepped closer and Derek reached out and tentatively ran his fingers over the soft, warm skin of her exposed ass. “Melanie has a nasty habit of wanting whatever she can’t have.”</p><p>“I can tell,” Derek said.</p><p>Anna kissed his neck and Derek closed his eyes as gentle waves of pleasure moved through his body, emanating from the spot where her lips met his skin. “Did you let her have you, Derek?”</p><p>“No,” he answered.</p><p>“Did you think about it?” Anna asked.</p><p>“For a moment,” he admitted. “I’m sorry.”</p><p>Anna smiled as her gaze met his. “You don’t have to apologize. There’s nothing wrong with considering something like that. After all, Melanie’s beautiful and I’m sure she made a compelling offer.”</p><p>Derek squeezed Anna’s ass and she smiled. “She did.”</p><p>Anna stepped back, took his hand, and led Derek away from the clearing. “Why did you turn her down?” she asked.</p><p>“Because I really like you,” Derek answered, “and it’s not worth losing you for the potential of losing my virginity.”</p><p>“She offered to fuck you?” Anna asked.</p><p>“She said she might bend over and let me have a go at her,” Derek replied.</p><p>Anna looked at him and smiled as they wound their way through the tall trees. “There’s a reason Melanie and I are friends,” she said. “We’re both a little different when it comes to sex. Some girls find talking about it scandalous, but we never have. She can be a bitch sometimes, but I do like her and there’s even a part of me that appreciates how bold she was in pursuing something thrilling with you. I’ll bet she would have let you fuck her, though. I think she really likes the idea of a guy cheating with her.”</p><p>“I don’t want to fuck anyone but you,” Derek said as they walked towards a massive boulder he hadn’t seen from the river.</p><p>“What if I won’t let you fuck me before the summer is over?” Anna asked.</p><p>“I’d be disappointed,” he admitted. “But I’m also pretty sure that I’m still going to enjoy spending the rest of my summer with you even if I don’t get to have sex with you.”</p><p>“I’m certain of it too,” Anna said. “After all, I make you feel good, don’t I?”</p><p>Derek nodded.</p><p>“This is where I brought Cooper,” Anna said as she led Derek around the backside of the boulder. She leaned against it and pulled him close for a kiss. “This is where I kissed him. This is where I felt his cock pressing into me as I sucked on his tongue.”</p><p>Anna kissed Derek again and welcomed his tongue into her mouth. She sucked on it, likely in the same way she’d suck on Cooper’s. She untied his swimsuit and pushed it to his feet before wrapping her soft fingers around his cock.</p><p>“This is where I stroked his cock,” she whispered. “Though his was much bigger than yours. I couldn’t even wrap my fingers all the way around it.”</p><p>Anna kissed him feverishly as she stroked his cock faster. Derek panicked a little as he felt his orgasm approaching with remarkable speed. He wondered if Cooper had felt fear over cumming too quickly.</p><p>“This is where he fucked me,” Anna said.</p><p>Derek moaned. There was something about the way she said it in the look in her eyes that filled him with desire. He wanted to fuck her. He wanted to be inside her like Cooper had.</p><p>“You’re not going to fuck me, though,” she said. “You wouldn’t last long enough and your dick isn’t big enough to make me feel like he did, so why would I let you inside me?”</p><p>Derek’s heart pounded and his cock throbbed in Anna’s hand. Her words were cruel, and yet for some reason they turned him on.</p><p>“I let Cooper fuck me from behind while I played with my clit,” she said. “His body was pressed up against mine as his cock moved in and out of me. He filled me so good, Derek. He filled me and fucked me so good. I came all over his cock. I soaked him with my juices. I told him how good it felt to have him inside me. I told him how good it felt to get fucked again.”</p><p>Derek put his hands against the boulder to steady himself as he felt his orgasm nearing.</p><p>“I let him cum inside me,” Anna said. “It’s still leaking out of me, in fact.”</p><p>Anna pushed a hand into her bikini bottoms and her fingers emerged covered in Cooper’s thick cum. She shoved them in her mouth, sucked them clean, and smiled.</p><p>Compelled by a force he didn’t understand, Derek leaned in and kissed his girlfriend. She moaned and opened her mouth. Their tongues danced and he tasted Cooper’s cum. It tasted no different than his own and Anna’s obvious delight in Derek’s eagerness to kiss her made her stroke him even faster.</p><p>“Anna, I’m close,” he said.</p><p>She reached into her bikini bottoms once more. Her fingers emerged covered in Cooper’s cum once more. This time, though, she didn’t take them in her mouth. Instead, she offered them to Derek. He parted his lips, took his fingers between them, and sucked them clean.</p><p>They kissed and once again shared the taste of Cooper’s cum as Anna’s hand brought Derek to a thunderous orgasm. His cum squirted on the boulder while his legs trembled so hard he thought he might fall over.</p><p>“Holy fuck,” he said. “Fuck, Anna, holy fuck.”</p><p>She kissed his cheeks and neck and let out a series of soft, low moans that seemed to enhance the pleasure of his climax, putting a bright smile on Derek’s face.</p><p>“I’d like to cum again,” Anna said when he’d finished. “Will you help me with that, Derek? Will you make me cum again?”</p><p>Derek knew he could have used his fingers, but he wanted to give Anna the best orgasm possible, so he dropped to his knees, pulled her bikini bottoms down, and ate her pussy. He didn’t care that some of Cooper’s cum still remained inside her and on her labia. He just wanted to give Anna an orgasm she’d remember.</p><p>“Good boy,” Anna said as she put a hand on the back of his head. “Make me cum. Fuck, make me cum, Derek.”</p><p>He did just that, and rather quickly, too. Anna’s moans drifted towards the sky and Derek felt deeply pleased at having satisfied his girlfriend in the way he’d become accustomed to. He liked that he got to make her cum after Cooper, too.</p><p>“Thank you for that,” Anna said as she helped Derek to his feet. They shared a soft, lingering kiss with just a hint of tongue and she said, “That was really, really good.”</p><p>“It was my pleasure,” he replied.</p><p>“I intend on letting Cooper have his way with me while he’s in town,” Anna said. “Are you going to be okay with that?”</p><p>“Of course,” Derek answered.</p><p>She smiled and kissed him again. Derek knew she didn’t need his permission to fuck Cooper as often as she wanted, but he liked that she’d asked.</p><p>“Let’s go back to the river,” she said. “I want to swim a little more before we head home.”</p><p>Anna took his hand and Derek couldn’t wipe the smile off his face as they strolled through the woods. His afternoon had gone even better than he’d hoped.</p>
