When the man started pumping his big prick in and out, the delicious friction against her sensitive cunt walls was sheer heaven to Sharon.

"Oh, you sweet bastard," she cooed as he increased the tempo of his lusty strokes.

The sound of her mother's passionate voice and the squeak of the bouncing bedsprings through the wall was driving Bonnie wild. Frantically rubbing her clit as she listened to the couple fucking in the other room, the girl could vividly imagine how Lou's cock must look plunging in and out of her mother's hot dripping slit. Bonnie had been fucked by plenty of the guys in the neighborhood, but listening to her mother and the man in the other room, the girl excitedly wondered how a big man-sized cock would feel in her twat. From the squeals of delight that were coming through the thin wall, Bonnie was sure that her mother was thoroughly enjoying the man's big prick.

"Oh, you sweet baby," she heard her mother whimpering as Lou increased the tempo of his lusty strokes.

Sharon had enjoyed her share of cocks in her lifetime, but she'd never found one any longer or thicker than this magnificent tool. It had been a long time since she'd been so deliciously stuffed with this much prick-meat, and the intense pleasure was incredible. On and on they fucked, each wild plunge of his shaft increasing the ecstasy they were both enjoying.

Listening to them through the wall as she lay there fingering her twat, Bonnie suddenly threw back the covers and lightly stroked her other hand across the warm tingling flesh of her nipples, feeling them starting to harden and swell under her teasing caresses. Lightly pinching and twisting her erect titty-buds, the girl pulled the finger of her other hand out of her slit and began sensually rubbing her belly in a slow circular motion, enjoying the tingles of pleasure that were streaking from her quivering nipples to the moist hotness between her legs.
