"No! Mom, let it shoot! It's killing me!"

"You want to shoot your cum, do you?"

She pinched his cock-head tightly, knowing that to relax the pressure would let the white cum fountain up from his balls. Then she shameless mother wrapped her fingers around his aching, throbbing fuck-pole and started beating his cock-meat again. Her right hand whipped up and down his throbbing, tingling cock-meat, torturing her son, keeping him at the very brink of cumming.

"Does this feel good, Mark?" she asked, her voice shaking with passion. "Do you move your fist this fast when you jack off? Do you, Mark? Mark, what do you think about when you jack off?"

His enormous cock had bloated to a lurid crimson shade now, as if it would explode. Sharon pinched his cock-head tightly and continued to whip her fist faster and faster up and down his hard-on. Mark grimaced, writhing on the bed.

"Let it shoot, Mom! Oh, fuck!"

"You think about fucking your mother when you jack off, don't you?" Sharon panted. "That's right, you think about sucking Mom's big, juicy tits and ramming this big cock of yours in and out of Mom's cunt. Will you keep your cock hard for me, Mark, if I let it squirt? Will you, baby? Mom's cunt is so awfully wet and swollen. No matter how hard you own now, Mark, I want you to keep your cock nice and stiff for me, so you can fuck the piss out of my tight, juicy little cunt!"

"Oh, Mom! Oh, Mom, please!"

Sharon finally released his puffy cock-head, simultaneously jacking his cock with her right hand. Mark shuddered as the hot, milky-cum sprayed out of his burning cock.

The blast was incredible, shooting out of his open piss-hole and squirting on the floor. Sharon watched the sticky jism spew out and almost forgot to shove his gushing cock back into her mouth.
