I Couldn't Help Myself...

Brandy knew her stepdaughter’s boyfriend was in the house. Her husband was gone for the week, and the girl had begged to let Rob stay over. Brandy said yes. Simple as that. She told herself she was building trust, but the truth sat right between her thighs every time she looked at him. Rob had a way of moving through the room that made her skin prickle. Tall. Dark. Calm. She kept catching herself staring at the outline of his cock pressed against thin sweatpants whenever he stretched. Her tits strained against silk every time she leaned over the kitchen island to offer him another glass of water. They flirted in safe sentences at first. Then the air changed. She told him to follow her upstairs. The bed was still unmade. She turned, already pulling the straps of her dress down her shoulders, big round ass swaying in invitation. Rob grabbed her hips and pushed inside without another word. Brandy moaned loud enough for the walls to hear, riding him in a slow, grinding cowgirl that made her heavy breasts bounce against his chest. She kept whispering she shouldn’t, kept moving anyway. Every wet slap of her ass against his thighs erased the guilt, leaving only heat and the simple fact that she needed this more than she needed to be good.
