That's hot. Your pussy must feel pretty good if he's groaning like that. Or he was just so turned on by your dirty talk. "Fill me with your hot cum." Yes, ma'am.
Put that hand down and take that cock balls deep. If he wanted a hand job, he could do it himself.
Would you like it if I made you suck my cock clean after fucking your ass?
To punish your ass, I would avoid lube and thrust into you hard and slow, making you say the number of thrusts out loud as I do it. Afterward, I would shove a dildo down your throat while fucking your ass to make you gag and clench your ass around my throbbing cock.
I say go for it. Could be fun.
