"Fuck me from behind," she said in a throaty voice. "I like getting fucked from behind, Tommy."

Susan rolled onto her stomach, pulling her knees up underneath. Tommy, sitting on his heels, watched the creamy roundness of his mother's naked ass with interest. As Susan pulled her knees under her body, her lovely ass checks parted, and she arched her ass back. Her pink cunt pooched from her thighs as she spread her knees, resting her head and shoulders on the bed, her ass high in the air. She shook her ass, inviting her son.

"Fuck me this way, Tommy," she purred softly, wiggling her ass for him.

"I like getting fucked this way. Your cock can go real deep this way, baby."

Tommy couldn't wait any longer. Seeing his mother with her naked, lovely ass high in the air, her cunt waiting, he wanted to fuck her again more than look, right now. He saw the crinkle of her asshole pull inward and his cock jutted out hard. Susan's finger clawed at the bedspread as she waited, breathless, for her son to ram his cock up her cunt again. She closed her eyes, a smile on her beautiful face.

Tommy brushed the head of his cock up and down the slit of his mother's cunt, feeling the wet heat blister it.

"Mmmmm, this is going to be very good, Tommy," Susan whispered. "You're going to really enjoy fucking me this way."

Tommy placed the head of his cock against the swollen lips of his mother's cunt, and his palms on her ass.

"Go in slow," Susan said. "Let me feel every hard inch go in my cunt real slowly, baby."
