Jake Finally Claims His Stepmom's Ass

I was nineteen, freshly home from my first year of college, and already losing my mind.

Vanessa, my stepmom, had always been a walking wet dream, but that summer she seemed determined to break me. At thirty-eight she had the kind of body that made men stupid: huge, heavy tits, a narrow waist, and an absolutely massive, heart-shaped ass that jiggled and swayed with every step. She knew it too. Around the house she lived in the tightest yoga pants imaginable, the kind that disappeared between her thick cheeks and left the twin globes of her rear bouncing like they were trying to hypnotize anyone who looked. Tiny athletic shorts were even worse; the fabric barely covered half her ass, and the constant sight of her thong lines digging into all that soft, tanned flesh kept my cock in a permanent state of aching hardness.

My stepdad worked long hours at the firm, often gone before I woke up and home long after dark. My eighteen-year-old stepsister, Kayla, was rarely around either, always out with her friends or her new boyfriend. That left me and Vanessa alone for hours every day, and she made sure I suffered.

I tried to be good. I really did. But every time she bent over to load the dishwasher, or dropped into a deep squat while pretending to look for something on the bottom shelf, her enormous ass would stretch the thin material until I could see the outline of her pussy lips from behind. My dick would throb so hard it hurt, leaking into my boxers while I stared like a perverted idiot.

The breaking point came on a humid Tuesday afternoon.

I was sprawled on the couch pretending to scroll through my phone when Vanessa walked into the living room in black seamless yoga pants that looked painted on. She put on one of her workout playlists, gave me a sweet little smile, and started doing squats right in the middle of the room. Slow, deep, perfect squats. Every time she dropped down, her massive ass cheeks spread and the seam of her pants vanished completely between them. When she rose, those two fat globes clapped together with a soft, fleshy sound that made my balls tighten.

I couldn’t look away. My cock was rock-hard, tenting my gray sweatpants obscenely. I was so mesmerized by the way her ass rippled and bounced that I didn’t even notice she had turned her head and caught me.

Instead of getting mad, Vanessa’s full lips curled into a wicked smile.
