You can't resist

You walk over to the naked woman in your bed and position yourself above her. You pump your dick inches away from her ass cheeks. "This is sort of weird," you think, but unable to stop yourself. Helplessly, you jerk yourself off as you watch Andrea breathe heavily in her sleep.

Finally you can take no more and feel your orgasm flooding towards you. "Turn away!" you think but instead you lean forward a couple inches and shoot your first volley, sailing over her ass and making a thin white line down her back. Dipping downward as you moan, your tip rubs against her ass cheek as you shoot again. Your white seed follows the contour of her ass as it explodes outward, creating a thick pool of cum which begins rolling down into her crack. More and more shoots forth from your groin, making a mess of her lower back.

Drained, you wipe yourself off quickly then collapse next to the mess you just made of Andrea. You fall asleep within seconds.
