"Oooohhh," the feminine voice groaned. "Ooohh Don, that feels so good."

Mikki stepped quietly to the door and peeked in. Her brother and the red-haired divorcee from 8-A were in bed together. They were both naked and Don was bending across her, sucking one of her tits while he caressed and massaged the other.

The young brunette gasped as she watched the sensuous writhing of the two bodies. She knew she should turn back to the front of the house and wait for them to finish before she went to her room. She should, but she stood frozen, watching the glistening bodies as they twisted about on the bed.

"Mmmmmmm," Don murmured to the redhead, "these are the sweetest tits I've had in my hands in along time."

He went back to work with his mouth, sucking softly on the heaving jug while his tongue depressed the tight nipple. His right hand fingered the soft flesh of her other tit while his left hand caressed along her thigh and up into the lush growth of auburn hair over her cunt.

"Yesssss!" the redhead sighed as she reached out until she was able to get her hands on his rigid, throbbing cock. She fingered it gingerly, then clamped her hand around it and began to pump it slowly and sensuously.

Mikki stood with her mouth open in horror. She had never seen an erect prick before. She had seen cocks, of course. She had seen pictures in biology books. She had seen the small pecker on her cousin's baby sons. She had seen a boy's cock once when she was seven years old, and she had played show-me with the little guy who lived next door at the time. A hard, swollen prick, though, was something new. She gasped at the enormity of it. The thought of all that meat going into a woman's pussy was frightening. It was frightening and exciting at the same time. She suddenly wanted to see it go in. She wanted to see Don fuck this woman.
