Monday morning

I had great weekend with Kimberley and her mom. Even better, my uncle let me keep my petite 18 year old cousin with perky c cups. I was told he would pick her up at the end of my birthday week. My friends came back around on sunday and gangbanged them for the day. we would let one close while we used one to fuck and another to stretch open wide.

I had the best dreams that Sunday night. i realized why as I woke up and i thought I was still dreaming. I hadn't realized i instructed the 2 girls to give me a blow job and rim job before I fell asleep and never told them when to stop. I woke up to Kimberley, still with her lips sealed to my ass with her tongue buried as deep as it could go. My cousin was deeply face fucking herself on my cock, gagging violently every time she **** her self down on it. My cock should be raw from the constant attention, but instead is was still comfortable, the nanomachines kept everything perfectly healed. i grabbed her by the pigtails she had in and started slamming her down on it faster. i soon need to cum and kept her down on it as i did.

"Fuck that's great cuz, fucking swallow it all for me." I tell my cousin as I come down her throat. Her body following the command even with the shaft lodged deeply in it. The feeling of her muscles gagging, trying to push it out switched to the opposite feeling. it was like she was trying to suck every drop of cum form my balls.

"Keep sucking i have something else for you" i tell her needing to take a morning piss. i let loose and she gulped it down. a little draining from her nose as i started fucking in and out of her throat as I drain my bladder in her. As i get up I noticed her stomach is swollen from the dozen loads she had gulped down over the night and the fresh load of urine on top of it. i realized Kimberly constant sucking and tongue deep in my ass had taken care of anything in my colon with her attention over the night.

"Go get showered and dress for school i have to show off my birthday presents." i tell the two. watching their perky asses as they go i went to have breakfast. It was a fact that with enough cum the nanotechnology would keep them healthy even on the liquid diet. Needing to clean up myself, I decided to follow them in. They are holding each other crying in the steamy shower. there is a feeling remorseful and guilt for a second before the nanotechnology rewired my brain to get sexually excited instead. every time it identified a pathway that would get in the way of making a man not follow its prime directive of having them using women to stretch it would erase or redirect the pathway. i didn't know that it was so though and couldn't care about them anymore so went with it. I couldn't help but make them bend over and take the shower head off to use to fuck their asses and cunts deeply. The doctor had used his technology to twist men into wanting to **** women constantly. No one under 18 realized just how pervasive the changes were before they went through it themselves. I realized that i was just as bad as all those guys i used to judge for taking thing to the **** with the girls. I also realized any shame or guilt seemed to be gone. I used to hate my dad for treating the females in my family like objects but now it was actually already a bit excited to think of seeing my sisters at the end of the week. i had always thought dad was sick for how he used them but all my reservations were falling away as i was buried elbow deep in both girls. their obvious discomfort only turning me on more.

After a deep cleaning i had them do there makeup and change into some slutty schoolgirl outfits
