She knew he was peeping her and jacking off. He tried to stay quiet, but she could hear his gasps and grunts, especially when he came. He looked at her through a small hole drilled in the bathroom wall. She enjoyed putting on little shows for him, teasing him, then giving him that perfect shot of her that made him blast his load, his grunts louder than he thought they were.
Then she would invite him to watch TV with her, imagining his cock rigid and spurting hot jets of cum as he dreamed of being inside of her tight 20-year-old pussy as he emptied his balls to her nude body in his bedroom next to the bathroom. She wore a t-shirt and no bra and a thong, making a point of stretching her legs and letting her t-shirt ride up her slender brown legs. Her nipples would harden and become easily visible, her 32C breasts loose under thin cotton. They were firm and full and white against her tan skin, not in need of a bra to remain upright. Sometimes his face would still be slightly flushed from his orgasm as they sat together on the couch, her body freshly washed and lotioned. Sometimes her pussy was freshly shaved, every black hair neatly removed from the fat lips of her innie pussy.
One night when they were alone for the weekend she wore no panties, and curled on her side, her bubble butt facing him. In agonizingly slow fashion, she let her shirt ride up her thighs, loving how his glances got longer and longer. His breathing got heavier when the edge of her pussy and asshole became visible. He gasped when she momentarily spread her thighs, exposing herself fully, allowing him to see the pink inside of her pussy and the darker pink of her tight asshole. She closed them, then got up to get a glass of water. When she returned she saw his cock pushing against his sweat pants. She sat down closer to him, her hand grazing the top of one of his muscular 18-year-old thighs. He looked at her and she smiled, increasing the pressure of her hand, now rubbing up and down his thigh and moving inward. His eyes widened. She smiled again and lightly touched his stiff cock. He sucked in his breath.
“Take your cock out for me.”
He took both hands and pulled down his sweats and his underwear, his erection popping free, the cap shining with a film of precum.
“Nice. I’m going to suck it now.”
She leaned forward and kissed the head. It jerked a bit and he grunted. Then she moved her tongue over the spongy, warm head as he sighed with pleasure. She cupped his balls and gently milked them, then put her wet mouth over his cock and slid her mouth down a few inches, eliciting a loud groan.
“Aaaaaaaahhhhh!”
She bobbed rhythmically, stll massaging his taut balls. She increased suction as she raised her mouth to the head of his cock, then lowered her mouth again. She moved her face so that the tip of his cock was rubbed against the side of her inner cheek. He moaned loudly.
