Years ago, when I was in college, I went out for the night with friends. We went to a few bars, met a group of guys and ended up at a party. We all had a good time, but one of the guys (let’s call him James) left a little earlier as he had class the next day. I ended up chatting with his dormmate (Frank), and finally, he took me to his dorm.
When we got there, the room was dark, but through the light of the streetlamp coming in through the window, I could see the sleeping form of James in his bed, lying on his side with his back to us. I thought Frank would tell him to skedaddle out of there, but Frank told me not to worry and that James was lightweight and was probably passed out from the drinking earlier. That was fine enough for me, and I ended up sitting on his lap, topless, while Frank, to put it frankly, went to town on my boobs. I always enjoy that, though in those days, most guys my age, despite loving big boobs, paid very little attention to them. But Frank did; he spent an age with his mouth on them, kissing, nibbling, biting and pinching my nipples with his fingers. And I enjoyed myself on his lap, moaning and encouraging him.
