Bobby gasped hotly as he jerked on his cock. He kept looking at his mother, but was no longer touching her thigh since he had turned to face her. Sharon wanted to tell her son to lift his balls out, that she wanted to see them, too. She wanted to tell her son to push his pants down, let her see everything… but all she could do was sit there, whimpering softly, and watch him blatantly jacking off.

Once again she tried to control herself.

"Bobby, not here," she moaned. "Please, go to the bathroom… don't do it in front of me… I can't."

Bobby pumped faster and faster on his cock.

"I'm gonna come, Mom!" he groaned. "I'm gonna come soon!"

"That girl." Sharon whispered in a thick voice. "She did this to you, Bobby. Seeing her lean over, what she showed, excited you too much. Please, honey, not here. Don't do that in front of mother."

Bobby pounded away, the head of his cock bulging tightly, dripping more and more. Sharon flicked her tongue across her lips, her cunt starting to squeeze and suck inward, her clit feeling as if it were going to burst.

Bobby lifted his ass, arching his hips upward, his fist flying rapidly with short, jerking strokes.

He was about to come now, Sharon thought frantically, her eyes glazed as they fixed upon the flare of his piss hole.

She watched raptly, breathing in hot panting sounds.

Bobby started grunting, his hips shaking.

"Ohhhhh!" he groaned.

Come juice squirted from his cock, arcing up and then, downward. It landed on Sharon's thigh. She felt as if she had been burned there, as though his come juice would raise a blister on her unblemished thigh flesh. She gasped as he kept gushing thick spurts of come juice. Two more splashed onto her thigh, the rest of his jism spattering the couch between them.
