Pull out and cum on her body

Some part of your brain knows you shouldn't cum inside of your ex-girlfriend, least of all without protection. You push her arms away from yours and just before you cum you pull out of her pussy and begin to unload wave after wave of hot semen onto her back. You cry out in pleasure and plant your hands firmly on the back of Anna. As you cum you ignore the fact that you're basically pushing her face into the couch and your body begins to relax and press against hers.

"Goddammit," you hear her say as she reaches back and grabs your still hard shaft, forcing it back into her pussy. All of your cum is spent on her backside, but she's concentrating on getting off herself.

With your cock back inside her she begins to rub her clit and pussy lips furiously. There's a quiet anger to her actions and for a moment she is completely silent. Then, after a minute of working on herself you feel her lips clench around your softening dick and a quick cry of pleasure breaks the silence.

"Ohh!" is all you hear as her body tenses and convulses in what you can only assume is her orgasm.

A moment later Anna shifts forward and your cock slips out without resistance. Anna stands and faces you, a hint of her own juice dripping from her well-used cunt.

"You broke my concentration when you pulled out. I'm on the pill, it would have been fine. Anyway, I need to get cleaned up. You can use the tissues on the end table to take care of yourself."

She heads for the bathroom and you can see your cum start to drain down her backside and into her butt crack. You can tell that you've disappointed her a bit, but that's actually a feeling you're pretty used to when it comes to Anna. Standing up, you clean off your dick as best you can and then make your way for the door.

What the hell even happened today? Did you really just fuck your ex? Your head is swimming with weird thoughts as you leave. The sounds of the shower turning on is the last thing you hear before you close the door.
