Stepson's Runaway Imagination

Fannie stepped out of the shower, water still dripping down her tits, towel barely hanging on when she crashed into Derek. The towel dropped like it got cut loose. Derek froze, eyes glued to his stepmom's naked body—round ass, soft tits, that shaved pussy right in front of him. He stammered like he'd never seen a woman before. Fannie grabbed the towel, wrapped it back around her like nothing happened. "Accident," she said, cool as ice. "Don't sweat it." Later she's fully dressed, moving around the house—vacuuming, folding laundry, bending over the kitchen table. But Derek's brain keeps cutting the clothes off her. Every time he sees her, he flashes to that wet, naked body. Her tits swinging while she bends over. That ass up in the air. The way her cunt looked between her thighs. He can't shake it. "What's your deal today?" Fannie finally asks, catching him staring. Derek mumbles about seeing her naked earlier, how it's stuck in his head. She studies him for a second, then smirks. "Alright. Let's get it out of your system." She pulls her top off first, lets those tits drop free again. Derek's cock is already hard when she drops to her knees, squeezes them around his shaft, and starts working him between her soft, slick tits. She spits on the head, watches it slide through her cleavage, tits pressing tight around him while she strokes him off with her chest until he can't hold back anymore.
