He gets extremely close to bursting, so he roughens up more and thrusts faster than ever before.
"A-Ahh~ Yes yes yes, r-ram me, ram me w-with your cock~!"
He slows down, bursting a load of cum into him.
"A-ah~ shit!~"
"Mhmm~! A-Ahh...~"
He continues fucking him again, cum splatters all-over but he ignores it.
"N-Noahhhh, y-you already came!"
"And I plan on doin' ya all day~"
"Mhmmmmm~"
He cums again. It feels so good that he can't stop.
"Ahh~ f-fuck!~"
"A-Ahh~! N-Noahhhh~"
