Seeing her father's eyes locked directly on her body in her nightie and panties, the slender 18 year old with small tits kneeled on his bed between his spread-open thighs, her own eyes glancing at his throbbing, fully-engorged, oversized penis.

Sci-Fi & Fantasy

It was such a perfect night! Despite the late hour the weather was still warm. A high level of humidity during the day had provided the perfect insulation as the sun disappeared.

Interracial Love

Editor's note: this story contains scenes of non-consensual or reluctant sex. *** 2. Discovered One night, after she left, I snuck down to my own car and followed her.

While out to dinner with my mother, I kept getting distracted by a woman sitting at a nearby table working her way through a bottle of wine. She was sitting all alone, hadn't ordered any food, and kept glancing between her phone and the door. The woman was near my mother's age, rather full-figured with a very large bust.
