Fascinated by her plump ass as she runs on the treadmill, I press my erect penis against her beautiful ass wrapped in jogger pants (fantasy). "Oh man... you like my ass that much?" She pushes out her ass, forcing her pants into the crack of her ass (fantasy). I press my erect penis against her, pistoning along the crack (fantasy). When I look down, pre-cum is already leaking from my glans (reality).
