Join (Circle Jerk with you)

You take a small needle and give yourself a small injection. It protects you from the cartridge effect so you can maintain clarity of mind. Still, you leave your clothes behind. They were going to get very messy soon.

You follow the sounds of mons as the guys began to circle around a massive circular table usually reserved for "family" meals. Every now and again, you find that one of the fraternity brothers cops of a feel of you. Sometimes it is your ass, sometimes your nipples and sometimes your balls. Once in a while , someone would swipe a stroke of your cock. There are too many of them near you to find out who did what but it feels really good regardless.

The moans and groans continued until someone said "i'm cumming." That is all it took as one after another, the guys shot their loads, you joining them in the middle of the orgasms. The table was drenched in cum. Everyone stood there until everyone was finished, playing with themselves as they came off their orgasms. Then came the clean up, in which you deftly sneak away from. You aren't sure if anyone caught you joining in on the fun as they were too focused on their own orgasms but you wanted to make sure you escaped from their post nut clarity.

You retreat back and get dressed. What could they work on next? Which effect?
