Author Note: In this Sandy is going to be thinking more about the nanites, also there will be some sex. I'm still trying to figure out what college I want to set this at, probably a state school but I don't had any favorites.
It was almost 5pm and as I headed back to my room I saw Alex there in the common room, in the same seat he was in when we pulled him into this adventure. "Hey Sandy, Jen said you wanted to talk to me"
"Yes, come on in", he hesitated, "Jen should be here any minute and I could use your help".
He reluctantly entered the room, a little uncomfortable being alone with me, this convinced me they were perfect for each other. No matter the changes Jen was still the same sweet, shy girl, it was hard to see it past the new diminished inhibitions now but if you knew her it was there and Alex is the type of guy I would expect her to date. Not even two weeks and they were in love, I'm sure they haven't said that out loud but I could see it.
I put my backpack on to my desk, turning to the pile of sheets waiting to be applied to the beds, having someone to help would make it go faster. I don't think even the nanites can teach someone a good way to handle a fitted sheet. I gestured to the pile and he got the hint, the beds were quickly made but, in an hour, or so I'll be washing them again, this change is great but it is going to deplete my laundry money. I should check if campus IT was hiring, wait till they get a load of me.
He sits down on Jen's freshly made bed, "So Sandy, what did you want to talk about?"
"I talked about this with Jen, I want you to fuck me in the ass."
It was like I hit him with a pillow, he actually inched back a little on the bed, "You want what??"
"I've never done anal and I wanted the first time to be with someone with experience and I know you have a lot of experience with Jenny's delicious asshole", I think saying delicious might have been too much but he didn't seem to notice. "She said it was fine with her as long as she was here"
I could see the conflict on his face, he's being offered sex with a girl, one with, I'm told, amazing tits, and in the ass no less. All this with the girlfriend's approval. That first night we broke his brain, this probably isn't so bad but he would probably need to process it and fresh reassurance from Jenny.
Ok, I got that part out, nothing more to do until Jen gets home, so I fire up the laptop. My typing wasn't so bad before all this but now I am lightning, I completed my programming assignment was done with nearly no thought or time. As I shut it down Jen rushed into the room, I think she was worried she would miss out on something.
"Oh good, you didn't start yet"
"Jen, you wanted to be here and I promised, also I don't think Alex would do anything without being sure you signed on"
Alex sat there, not sure if he was part of the conversation. Jen finished putting away her backpack hugged Alex on the bed, rubbing her tits into his face which looked quite good to me.
"Jen, are you two sure, are *you* sure?" Alex wouldn't do anything without that.
"Oh, that is sweet, don't worry I'll be right here. If you are okay with this, I don't have any problem with you fucking Sandy in the ass ... just this one time."
"Um, I guess I'm fine with it"
Jenny seemed excited at that but before I knew it, she took the next step, "Sandy, can I see your tits?" and that did it, I started to undress. She turned to Alex, "just wait till we 69 and she will be warmed up", and as I walked over to her bed, she handed Alex half a tube of lube. Half? Darn Girl!
I put my arms around her as she worked from tit to tit, I was probably dripping on the sheets at this point, this was the 5th time this happened and I loved it even more each time. Jen paused and laid down, I got onto the bed on my hands and knees over her and didn't wait a second to dive into her pussy.
In the back of my mind, I knew that I was on the bed with my ass pointing at Alex, during the lead up he watched the show but now I think he was finally getting undressed, it was going to happen, I was so excited.
I felt the bed shift, and felt a hand on my lower back, Alex's hand, this was about to happen!
Jen pulled her head away from my pussy, "Alex dear, let me". Jen took his dick and started to suck on it but just for a few seconds then she guided him to my asshole. He pushed in, his head passing the sphincter and I let out a low moan into Jen's pussy, he didn't move because he was concerned about me which I thought was very sweet at the time, Jen has a wonderful, caring boyfriend.
"I'm good, I'm amazing, pound away" and he did, it was a different feeling and I bet it would be a little less comfortable before our change but now it was just a different flavor of ice cream, delicious but not the same flavor as fucking me in the pussy. Jen was back at my clit and I knew that I had a few seconds from an orgasm.
When it hit, I overloaded, I didn't fully pass out but it was close. My pussy, my ass, every inch of my skin in contact with Jenny and Alex seemed on fire. As expected, anyone I was in contact with had an orgasm, in fact it was tough to tell who triggered it, not sure it matters.
Jen was breathing hard; I was holding his dick in my ass even as he deflated a little, I could feel him push away and it was incredible. I started to get up but Jen grabbed me by the waist and held me in place me while she licked my asshole. I felt it build, I was going to climax again and then it hit which surprised all 3 of us. I felt another anal orgasm, Jen did as well and the big surprise was Alex who was reaching down to caress her head, Alex had a climax triggered by that contact.
He was sitting there deflated when suddenly he was rock hard and exploding all over the sheets. Since he hasn't had his nanites activated this was a little surprise for him, Jen and I started giggling.
"Sandy, I need to ask a favor?"
"How can I refuse after the amazing favor you both did for me?"
