He grabbed the bag, yanked down, and hoisted it to empty the grass into the bin marked for yard waste. Zack upended the bag and a small trickle of freshly cut grass poured out. Something was blocking the opening so Zack shook it harder.</p><p>He should have simply reached up into the bag to loosen the clump of grass that was clearly blocking the opening. Instead, he tossed the bag across the lawn and let out a loud, frustrated scream.</p><p>As Zack fumed, the sliding glass door open and Camilla stepped onto the back patio in a sports bra and a skintight pair of workout tights. Her body glistened with sweat – she’d left for a run nearly an hour ago – as she sipped a glass of ice water, smiled, and sauntered towards him with an alluring sway in her hips.</p><p>“Zachary, you seem frustrated,” she said.</p><p>“What gave it away?” he asked.</p><p>Camilla laughed and stepped close enough to Zack that her big breasts nearly pressed into his chest. He studied her eyes and her luscious lips and his cock stirred to life. “What’s the matter, Zachary? What’s got you so frustrated?”</p><p>“It’s just…all of this stuff with Bella…I don’t know, it’s just hard,” he said.</p><p>Camilla smiled and reached up to caress Zack’s face. “Did you expect it to be easy, Zachary?”</p><p>He shook his head.</p><p>“No, of course not. You’re a smart young man, so you knew it would be hard. You’ve set the woman you love free and she’s taken advantage of your generosity by fucking Luke with wild abandon, hasn’t she?” Camilla asked.</p><p>Zack nodded. Bella had fucked Luke almost every day for the past two weeks. “I don’t know what to do, Camilla. It’s obvious that Bella likes fucking him more than she likes fucking me, but that doesn’t make it any easier. I’m worried about losing her. I’m frustrated, too, because Bella and I aren’t having sex as much as we used to.”</p><p>Camilla took Zack’s hand and led him towards the patio. They sat under the shade of the umbrella and she said, “Of course you’re not having as much sex. That was expected, wasn’t it? Bella’s getting what she needs from another man, so she doesn’t need you with the same frequency. She understands you have needs, but you don’t deserve to have those needs met every day, do you?”</p><p>“I…I don’t know,” Zack said. “I mean, I guess I don’t, but that doesn’t make those needs go away. It doesn’t make my desire any less.”</p><p>Camilla smiled, leaned forward, and put her hand on Zack’s knee. “It probably doesn’t help that you’re turned on by the idea of my daughter fucking another man.”</p><p>Zack’s embarrassment made it impossible to hold Camilla’s gaze.</p><p>“Zachary,” she said as her fingers moved up his thigh, “there’s no need to be embarrassed. I understand why you think you should feel embarrassed, but you’re wired differently than most men. You’re willing to put the pleasure of your future wife far above your own, and you’re willing to do that because it turns you on. It excites you to know that Luke fucks Bella better than you do and there’s nothing wrong with that. In fact, you might find some of your frustration would abate if you embraced that fact.”</p><p>Camilla grasped Zack’s cock through the thin nylon of his shorts and he groaned. Her fingers expertly massaged him to an erection as he surrendered to the naughty thrill of an over-the-shorts handjob from his future mother-in-law.</p><p>“That’s it,” she said in a soft, soothing voice. “Just let go of your embarrassment. Let go of the frustration that comes with it. Close your eyes for me, Zachary.”</p><p>Zack closed his eyes and Camilla stroked him faster through his shorts.</p><p>“Now imagine Bella with Luke,” she instructed. “Picture them in Luke’s truck. Picture Bella sitting astride her ex-boyfriend. Picture her kissing the man that fucks her better than you. Picture his hands on her bare ass as she rides his cock. Picture the look on her face as Luke gives Bella the kind of pleasure she craves, the kind she can’t get from you.”</p><p>“Camilla…fuck…I might…” Zack said.</p><p>Camilla released his cock and Zack opened his eyes and saw a bright smile on her face. “Were you close to cumming in your shorts, Zachary?”</p><p>Zack nodded.</p><p>“That’s not something to be embarrassed about. That’s your body telling you that you’ve found the right relationship. I barely played with your cock and you nearly unleashed like a teenage boy seeing his first pair of tits, Zachary. Instead of running away from what turns you on, you should embrace it. You should run towards it,” Camilla explained.</p><p>“How?” Zack asked.</p><p>“Ask Bella to tell you how good sex with Luke is,” Camilla replied. “Ask her to describe how it feels when he fucks her. Ask her to give you the details of her liaison with him when she gets home. Most importantly, ask her if it’s okay for you to masturbate while she does, or, if she’s feeling particularly generous, ask her if she’ll give you a handjob while she talks about Luke satisfying her desires and giving her the kind of orgasm that keeps her going back to him.”</p><p>“Won’t she think that’s weird?” Zack asked.</p><p>Camilla laughed and replied, “Did she think it was weird when you told her to think about Luke as you fucked her? Did she think it was weird when you went down on her after she was with Luke the first time? Did she think it was weird every time you went down on her since?”</p><p>Zack shook his head.</p><p>“Then she won’t think it’s weird that you’d like to receive a handjob while she tells you about the great sex she had with her ex-boyfriend,” Camilla said. “There’s a chance she’d be willing to masturbate with you, in fact. You shouldn’t underestimate my daughter, Zachary. She might not want to fuck you with any great frequency anymore, but she’s likely quite a bit more adventurous than you might suspect and if you’re willing to ask, she might be willing to meet your sexual needs.”</p><p>“Thank you, Camilla,” Zack said. “I actually feel better.”</p><p>Camilla stood and looked down at him with a smile on her face. “That’s good, Zachary. You’ll need to get better at managing your feelings, though. Today you took your frustration out on the lawnmower and my yard waste bin, but someday you’ll take it out on Bella, and I won’t have you yelling at my daughter because you’re frustrated.”</p><p>“I know, I’ll get better,” Zack replied. “I will. I promise.”</p><p>“Stand up, Zachary,” Camilla said.</p><p>Zack stood and she reached out, untied his shorts, and yanked them to the ground along with his underwear. She took off her sports bra and Zack couldn’t help but focus on her breasts. Camilla wrapped her fingers around his semi-hard cock and stroked him slowly. Zack wasn’t sure what he’d done to deserve such a reward, but he wasn’t going to argue about it.</p><p>“Does my hand feel good, Zachary?” Camilla asked.</p><p>He nodded and she moved behind him while her fingers continued to move up and down his shaft. Camilla pressed her body against his and Zachary closed his eyes. Her breasts felt spectacular against his back and she was doing something truly magical with her hand, ensuring an orgasm would soon overwhelm him.</p><p>“Cum for me, Zachary,” Camilla said.</p><p>Zack was hit with a wave of intense pleasure at the idea of his girlfriend’s mom telling him to cum. His cock surged in her hand, his balls tightened, and he unloaded. As he did, Camilla held out her other hand to collect most of his cum.</p><p>“Open up,” Camilla said mere moments after Zack finished cumming.</p><p>“What?” he asked.</p><p>“Open your mouth,” Camilla said. She raised her hand and Zack stared at the puddle of cum resting in it.</p><p>“No,” he said.</p><p>Camilla pressed her body tightly against his, pinning Zack against the table. She reached up, dug her fingers into his cheeks, and pushed his mouth open. Before he knew it, Camilla had poured every drop of Zack’s cum onto his tongue.</p><p>“If you spit out your load I’ll bend you over this table and spank your ass until you’re weeping,” Camilla said.</p><p>The fierce, angry tone of her voice convinced Zack she would do it, so he closed his mouth and swallowed the cum she’d just fed him. A deep sense of revulsion filled his body as Zack barely held off from gagging at the terrible taste that filled his mouth and the thick film that coated his throat.</p><p>“I will not, under any circumstances, allow my daughter to marry a selfish man, Zachary. You will learn to control your frustrations. You will learn to come to terms with your many shortcomings. You will embrace that in your case, being a good husband means encouraging my daughter to meet her sexual needs with any man she desires. If she chooses to deny you access to her pussy for months at a time, you will thank her for it. You will resolve to come up with creative solutions to what frustrates you instead of acting like an insolent boy and demanding that Bella do the work to cure what ails you. Do you understand, Zachary?” Camilla asked.</p><p>“Yes, Camilla, I understand,” he said. “I’ll do better in the future. I promise.”</p><p>Camilla stepped back and gently spun Zack around. She offered a warm smile and said, “That’s very good, Zachary. Now, you’re going to help me have an orgasm.”</p><p>“It would be my pleasure,” Zack said.</p><p>“I’m sure it would, though it’s going to be a little different this time,” Camilla replied. She slipped her fingers into the waistband of her workout pants and pushed them over her hips and down to her knees. “You’re going to worship my ass while I masturbate. It’s terribly kinky, but I like the idea of you licking my sweaty asshole. On your knees now, Zachary. Press your face between my ass cheeks and lick my asshole. Lick everything, in fact. Lick up all the sweat I built up during my run.”</p><p>Zack fell to his knees, spread Camilla’s ass cheeks, and pressed his face between them. He licked her flesh and the overwhelming taste of sweat hit his tongue. Camilla moaned, though, and Zack could hear her finger moving in and out of her wet pussy. It wasn’t particularly pleasant eating her sweaty ass, but Zack was going to do as she desired until she climaxed.</p><p>“Zack, this was lovely,” Bella said as they finished off the last bites of the exquisite dessert they’d shared. “Thank you for taking me out to dinner.”</p><p>Zack smiled and reached across the table to take her hand in his. “It was my pleasure, Bella. I actually have really good news, too.”</p><p>“What is it?” Bella asked.</p><p>Zack’s smile blossomed into something bordering on giddy and he said, “I got a job!”</p><p>“Really?” Bella asked. “Zack, that’s amazing. Where?”</p><p>“At this incredible adventure company,” Zack said. “They do all kinds of outdoor stuff. Mountain biking tours, river rafting, crazy ski trips during the winter, hiking, even mountaineering for the really experienced people.”</p><p>Bella felt a mixture of relief and elation. Months had passed without Zack getting a job and she was a little concerned he’d have to resort to doing something he hated just to save face. “Zack! That’s incredible,” she said. “Why didn’t you say something earlier? This dinner should have been all about celebrating you.”</p><p>“Oh, no, I mean, it’s nice to have a job, but this dinner was really about me wanting to take you somewhere nice. I don’t know, I kind of just wanted to celebrate the fact that I love you and that we’re together,” Zack said.</p><p>For just a moment Bella thought she might cry. There were times when she still felt guilty that she was having so much sex with Luke, even though Zack always encouraged her to do so and seemed genuinely okay with it. If anything, he seemed happier than he’d ever been now that she was having sex with her ex-boyfriend. That guilt washed over her as Zack expressed his love for Bella and it brought with it a well of emotion.</p><p>“Did you sign the bill?” Bella asked.</p><p>“Yeah, why?” Zack replied.</p><p>“Let’s go,” she said.</p><p>Bella stood and grabbed Zack’s hand. They rushed through the parking lot and she pushed him against the car and kissed him with incredible vigor. Zack offered no resistance, welcoming her tongue into his mouth and her hand between his legs. His cock was nearly erect by the time Bella found it, a surefire sign that he was into whatever she wanted to do.</p><p>“You deserve a reward,” Bella said before kissing his neck. “I know it was hard finding a job and a lot of guys would have given up on finding the job they really wanted. You didn’t, though, and it paid off. You deserve a reward, Zack. A very naughty reward.”</p><p>Bella sank to her knees in the parking lot and looked up at Zack as she unzipped his pants.</p><p>“Actually,” he said. “I know this might sound weird, but if you want to give me a reward there’s something a little different you could do for me.”</p><p>Bella was a little surprised Zack was turning down a blowjob, but she looked up at him and said, “Anything.”</p><p>“Will you…will you tell me about it?” Zack said.</p><p>Bella stood – he clearly wasn’t interested in getting head – and asked, “Tell you about what?”</p><p>“About you and Luke,” Zack said. “I know you told me about it that first time, but that was only a little bit and you haven’t really since, and the truth is, I want to hear about it. I want to hear about what it’s like for you when he…well, when he…”</p><p>“When he fucks me?” Bella asked.</p><p>Zack nodded.</p><p>Bella saw a mixture of lust and nervousness on his face. He really did want to hear about it, but he seemed a little scared, too. She didn’t want him to feel scared. There was no need for that. Bella unzipped Zack’s pants and pulled his cock out. She saw his eyes dart around the dark parking lot, but she didn’t really care if someone saw them fooling around.</p><p>“Three nights ago I stopped by Luke’s bar on the way home from work,” she said as her fingers moved up and down Zack’s stiff cock. “We had a drink together but I don’t remember what we talked about. I spent the entire time thinking about how good it was going to feel once I had his cock inside me.”</p><p>Zack groaned and Bella kissed his neck and unleashed a moan like she had Luke’s cock inside her in that moment.</p><p>“I took him out to my car. I sucked his cock in the back seat as he played with my pussy. I was soaked, Zack. I wanted him so badly. I nearly came while he was fingering me. I didn’t have a condom so I told him to let me know when he was going to cum and then I hopped on his cock and took him for a ride,” Bella continued.</p><p>“Fuck, Bella, that’s so fucking hot,” Zack said.</p><p>Bella moaned again, this time a little louder. She knew she was running the risk of someone hearing and walking over to see her jerking off her boyfriend in the parking lot, but Bella was too far gone to give a damn.</p><p>“It felt so good when he filled me, Zack,” she said. “It always feels like he’s stretching out my pussy when he first fills me. He’s so thick and it feels so fucking good inside me. It feels better when he fucks me without a condom, too. I know it’s bad and I shouldn’t do it, but it just feels so fucking good to have his bare cock inside me.”</p><p>“Did you cum on his cock?” Zack asked.</p><p>“I did,” Bella said. “I came hard and I came quick. I was so turned on I couldn’t help it. I filled my car with screams of pleasure as my pussy spasmed around Luke’s cock. We kissed as my thighs trembled and then I lifted my pussy off his cock and took him in my mouth again.”</p><p>“Did he…did you…” Zack asked.</p><p>“He came in my mouth,” Bella said as her lips hovered close to Zack’s. “He came in my mouth and I swallowed. I swallowed his cum in the back seat of my car.”</p><p>“Oh…fuck,” Zack said.</p><p>His cock swelled up and Bella stepped aside and watched it launch several thick shots of cum that landed on the door of the SUV parked next to theirs. She looked up at Zack to see pure pleasure on his face. It felt good to make him feel that good, and it seemed like her incessant guilt wasn’t really necessary. Zack clearly enjoyed the fact that she was fucking Luke. Maybe Bella didn’t have to feel bad about it.</p><p>“Congratulations on the job,” she said.</p><p>Zack laughed and tucked his cock back into his pants. “Thank you. For the handjob, too. That was really hot.”</p><p>“You know, I got kind of turned on talking Luke,” Bella said. “I know you didn’t want me to give you head, but would you mind giving me head?”</p><p>“Not at all,” Zack replied. “In the car?”</p><p>Bella leaned against the car, unbuttoned her pants, and pulled them down to her knees. “How about right here?” she asked.</p><p>Zack smiled and dropped to his knees. A moment later his tongue was working her clit and his fingers were inside her. An orgasm wouldn’t be far behind, especially as Luke popped into her head and she relived that scene in the car once more.</p>
