I think the most trouble we had was biology. The professor snuck in some killer lab stuff that had us digging to find the information to perform the n...cessary tests and analyses. I'm sure they didn't figure on the three of us working together and coming up with the answers. We were the only three to receive a grade on the test.Chemistry turned out to be similar to biology, but the three of us were lab partners with one other person. The result was the other person didn't really have to do much,. Her breathing intensifies from the stimulation of my tongue on her love holes.I move in closer and use my nose to slide the cum up and down her cunt lips, all the while breathing in through my nostrils and out my mouth on her hot cunt and asshole.

I ask her, “how many guys came in here?” as I lightly flick my tongue on her cunt lips.Between her deep breaths she quietly whispers, “three without condoms.” That. Anyway when I got home I changed and went to bed.On shift during quiet periods we'd sometimes wondered what it would belike to magically change sex. I said I'd hope if it was going to happenthen let it happen during my sleep because, if I have to get up to peeduring the night or first thing in the morning I will sit to pee, so Idon't have to turn on any lights and I can remain in a semi comatosestate.That is exactly what happened, I'd got up a couple of times to peeduring the night and didn't. I wanted to jump right on and feel your sloppy snatch with my dick.”Sis grinned at him, “I’ll remember that next time and maybe stop by your room if you’re there. I don’t get two different dicks in a row very often so that would be a treat for me too. Hey, I’ve got a hot date tonight so how about if I bring him back here? You stay home, nice and hard and ready for me!”That would work out just great, Tommy thought. Peggy wanted him to stop over in the afternoon because she had a date that night.
