nice like that bud, fucking a hot mans ass and feel his prostate contract against my cock, and a second later feel your hot sperm splat on my big pec shelf , then my abs, keep your ass flexing,and your cock cumming and as your load tapers off, start pumping out ropes of cum in your ass, hitting your prostate with those first strong ropes make your cock flex up again and pump out a few more heavy ropes of cum.
once you had that bud your always looking for a big cock to press against your prostate when it contracts against that heavy meat. make your cum load strong, big ropes of cum, love feeling strong hot rope of cum splat on my big pec shelf and hard abs as I keep hitting your prostate as you blow bud.
next time he needs to cum with your big cock up his ass as you jack his cock meat, see how it feels to have his prostate contract, but it's up against a hard cock, makes him blow those ropes longer and harder, then it's time to feed him cock and cum, training him can take weeks.
