Quickly hooking his fingers into the waistband of her panties, he peeled her filmy briefs down over her legs and ankles, dropping them onto the floor. His cock began throbbing even more violently in his pants as his eyes feasted on the dark triangle of pussy hair and her juicy slit that was peeking out from the silken curls.

"Honey," she whispered, feeling the hot juices oozing out from between her legs. "Please take your clothes off so we can fuck."

Standing up, the man quickly disrobed and suddenly his hard-standing cock was deliciously exposed to her in all its glory. Staring at his hard-on, Brenda could hardly wait to feel it stuffed up between her legs.

Frank and Brenda were both so involved in each other's naked bodies that neither of them was aware that Robin was watching them from the hall. Having I heard their moans of passion from her room, the girl had walked out just in time to see Frank drop his pants and shorts. She couldn't get over the size of his big prick. She had thought all cocks were about the same size as Mark's, and she was simply stunned by the sight of this huge cock.

"Oh, honey," she heard her mother whisper. "Why don't you lie down and let me fuck you?"

"You are in a horny mood," he laughed.

"I want to be on top for a change," she giggled.

Frank lay down on his back, and Brenda straddled his loins on her knees. Reaching down between their bodies, the horny woman grasped the thick base of his throbbing shaft and stuffed it between the juicy lips of her leaking pussy. Quivering with anticipation, she felt his big blood-swollen knob slowly spreading her cuntlips apart.

Watching from the hall, Robin couldn't understand how any pussy could possibly take that big cock. She knew it was wrong for her to be peeking, but it sure was fun watching them. Robin was getting all hot and itchy between her legs as she saw the man's prick entering her mother's juicy twat.
