Dirty windmill

In the middle of a group sex session , when someone’s is receiving anal , without using the facilities before hand and when the cock is ready to cum it pulls out and spins in a windmill fashion to evenly disperse the offering to all involved in the room

I walked into a room and there was a man performing “the dirty windmill”

Cheers and gasps !
