I did this with my best friend and his wife. I kept my cock still and just enjoyed my buddys cock stroking up and down on mine. He finally gushed a load all over my cock. It felt so hot. Then I finished fucking his wife. Cum is the best lube ever.
nothing in this world better than stuffing your cock in an occupied hole....that feeling of super tight pussy on one side, stiff hard cock on the other. Only time I got to try it I shot a massive load after a few dozen strokes, coated her pussy and his dick in cum.
But I need to work on my flexibility, lol!!
