Susan began to run her hand about her son's body now, feeling more than just his cock. She cupped his balls inside his pants and squeezed them, bringing a gasp of hot delight from her son. Scooting her hand behind him, she caressed the cheeks of his ass, wishing she could feel his bare flesh without those tight jeans. She cupped one ass cheek, then the other, trailed her finger up and down the crack of his ass, then back in front to close her fingers about his cock once more.

Below, they could see Mary twisting her hips, grinding her cunt into the pillow. Susan wished they could hear her soft sighs of pleasure, but they were three floors up and sounds that soft did not reach them.

"See Mary's ass, darling," Susan whispered, her voice thicker. "See how she wiggles her cute tight ass, Bobby. She's pretending she has a cock up her cunt. Maybe she's fantasizing her pillow is you… and she has your cock deep inside her hot, wet pussy, fucking it. All you have to do is lie there and enjoy it, Bobby. Mary is doing all the work for you. She's fucking you while you just lie still."

Her hand squeezed his cock hard as she moved it back and forth.

"Your cock is inside her hairy cunt, Bobby, fucking that hot tightness. Doesn't Mary's cunt feel good around your sweet, hard, oh so precious cock? Feel her pussy grip your prick, honey? Feel how her cunt eats you up…" Her fist squeezed and stroked. "You're going to make her come, baby. Your cock is going to make Mary's cunt come and when she does, that hot pussy will squeeze so tightly… and you'll come, too. You'll come up her hot cunt, Bobby."

Susan enjoyed the increased throbbing of her son's cock, her cunt pulsating, her stomach rippling. She felt as if she would come again the way she had the day before. She wanted it, wanted to come so badly. Her fist moved quicker on Bobby's prick, sliding to the swollen cockhead, then pressing back on it tightly at the base. Bobby was making choking sounds now, his eyes huge as he looked down at Mary's twisting naked ass. Susan pumped and stroked, whispered her lewd words to him, helping him dream, helping him fuck Mary in his young mind.
