I know you want to cum stroke boy, so here's the deal. Take your index finger nail side to the underside of your throbbing stick and using only UP STROKES, run the finger up the underside of your pee pee until you are just about to explode, just before you blow or just as you start, HANDS OFF and RUIN that orgasm.
Nice, let that spunk drip into that glass. I hope you are thirsty, because we have so much more to milk from that pathetic little prick.
