You try not to but

Your small cock started to ooze out your droplets all over his chest. Your wet load running down his hairy grey body. You loudly not believing how his cock was able to make you cum.

"Ohhhh yes sissy that a nice little squirt. I hope you like cumming like a girl because this well be the only way your ever gonna cum again." Deshaun grandfather say while still fucking you hole.

Your cock growing small as it flops around as he fuck you. You look at his face as you felt his balls tightening up.
