Days and even weeks passed for Peter, and the life of a penis became both normal and enjoyable for him. He was fully devoted to his former brother, doing his part to keep the Dan's body satisfied and in working order. He didn't have all that much to do, but he felt that what he did was necessary and fulfilling. After all, what man of Dan's age and level of promiscuity would feel entirely complete without his cock?
Peter found that he was forgetting what it felt like to pee or have an erection. Sure, Dan did it every few hours, thanks to Peter, but Peter only had weeks-old memories of what it was like to actually have penis. He remembered it felt good most of the time, and Dan felt the same way about him. Peter actually came to appreciate not getting hungry or thirsty anymore, because he remembered that didn't feel good if there wasn't any food or water around at the moment. In hindsight, the idea of having to take in whole meals on a regular basis was exhausting even to think about! That was a job for the mouth, stomach, and the rest of the digestive system. Peter's job was to let things out, not to let them in. He was more than happy to let the rest of Dan's body nourish him in exchange for doing his job.
Of course, Peter still found himself a bit frustrated that he couldn't remember what any of his favorite foods tasted like anymore. He knew he'd never taste them again, so perhaps it was for the best, but it was still a bit jarring to realize how much of his old self he had seemingly lost. Sometimes Peter tried to remember things for old times sake, just to remind himself that he was still him. He tried to remember things he'd learned in school or what it felt like to have moveable appendages. Sometimes he felt like he had a pretty clear idea of whatever he was trying to remember, and other times it was all foggy. He just didn't need to know all that much in order to do what he'd be doing from now on. He knew more or less when Dan was due for another erection, and how to tell when Dan needed him to drain off another load of urine. He knew the joy of being a source of sexual pleasure for Dan, and he knew the pride of launching out the sexual fluids that reminded Dan that he was a man. And, of course, Peter knew when he had plenty of time to just dangle idly and get some rest.
Peter had already facilitated several sexual escapades since Dan fucked the drunk woman at the party, and he'd learn to take for granted that most of his loads would go off into mouths and condoms to avoid risk of actual pregnancy. But then, finally, something interesting happened.
"HEY, DAN, OPEN UP YOU BASTARD!" came a shouting voice pounding knock at the door. Dan opened it.
"Anita, fuck, what are you doing here?"
"You knocked me up at the party, I know it was you. I hope you are ready to be a daddy, because it'll be here in a few months, and you'd better believe that you're gonna pay up. I am NOT raisin' a baby on my own."
"Why don't you just get an abortion?"
SLAP! "If I do that, it will be MY choice, NOT yours, and for your information I'm still deciding. Either way, I just thought I'd let you know. You haven't called or texted me since that night, but you are going to be hearing quite a bit from me starting now, and I WILL track you down if I need to. So man up and quit actin' like a two-year-old."
SLAM! The door was closed, and Peter felt Dan's pulse quickening in his veins. Peter was partially distressed by the sudden shock and anger since they had obviously distressed Dan, but Peter also felt a certain pride deep inside himself. Throwing up Dan's semen on occasion really COULD do something important, even more than the simple joy of making the rest of Dan's young adult body feel good. It could actually produce new life inside a willing female body. Peter had the power to let Dan pass along his genes. And if this new baby was successfully born, Peter looked forward to staying there between his master's legs, doing his part to help Dan be a good father for possibly years to come.
