These were on Literotica from an author named sweetsock, but he deleted his account. Only the first chapter is available via the wayback machine. Anybody happen to collect the other three chapters?
I downloaded and assembled these from forum posts elsewhere, so they're in Word format since WordPad seemingly doesn't exist anymore. Basically these are all similar in that wife/girlfriend of author sees huge cock on skinny kid, is entranced by it, massive orgasms, cuckolding ensues).
