She stood up and casually wrapped it round her waist leaving her cute small tits on display. I saw that her nipples, though not seemingly aroused, wer... erect and much to my chagrin about twice the size of my own. "There you go, nice and cold, that'll make you feel better. How was your journey?" Same old, same old." There was a pretty little nerdy girl who made me horny, made my nipples really hard. I wanted to add. But of course, I didn't. I continued. "The tube was chaotic, it was packed. Some. My cock was about to cum.
