"What on earth do you think you're doing?"

"Why, J-j-Jason!" Lisa sputtered. "What on earth do you think you're doing?"

Lisa felt fuck-juice rushing into her pussy as she realised that she couldn't take her eyes off of her boy's enormous prick.

His prick was the longest, fattest, stiffest cock she'd ever laid eyes on in her life. Her husband John’s cock was much smaller.

"Jason, you put your prick away!" Lisa sputtered. But she couldn't stop staring at his cock, her cunt throbbing harder and harder. She watched his giant, juicy cock twitch up and down. "Jason, this is disgusting! How dare you expose .....?"

Jason wrapped his hand around his gigantic fuck-pole, then jacked on it.

Lisa's mouth dropped open as she stared transfixed at the huge, rosy knob of his cock.

His puffy, reddish cock-flesh was swollen to bursting, and milky, sticky-looking drips of spunk oozed out of his piss-hole. Jason’s cock throbbed in his hand as he jacked on it. “I thought about you when I beat my cock- meat.”

Lisa dazedly watched pearls of jizz drip from his aching hard on to the carpet.

"I want to fuck you, Mom!" Jason moaned hoarsely. "I can't fucking help it! You turn me on so much. Oh, shit, Mom, I think about fucking your pussy every single, fucking day!" He continued to jack on his enormous fuck-tool, staring openly at his mother's naked body.

Lisa realised that her breathing had quickened until she was nearly panting. Her cheeks were red, and her nipples were stiff and tingling. Her pussy was so wet that it was nearly dripping. Never in her life had she felt so incredibly eager to cum. ‘I want to fuck my own son!’ she thought dazedly.

‘Yes, I really do! Jason wants to fuck me, and now I want to fuck him too!’ Lisa felt herself moving forward, her enormous tits heaving as she stared down at her child's prick. She felt as if she no longer had control over her own actions.
