On her back

Katie doesn't even have her wits about her yet when you sit up and shove her backwards onto the bed with a thud. Scrambling out from underneath her, you push her legs back against her chest, revealing the now well-used hole and shove your cock inside without hesitation or warning. Katie lets out a throughly unladylike grunt as you ram your cock into her gut unexpectedly.

“That's it. Take my cock.” You growl, fired up by the sight of her trapped below you as you impale her.

“Oh god, you're gonna wreck my ass.” She mewls, fueling your momentary wave of sadism. You pound her once again, your balls clapping against her ass cheeks as you plow her.

“Yes! Yes! YES! YES!” Katie's cries become steadily more passionate with every plunge inside her, until finally she tenses up for yet another climax. Your hands grab her legs firmly, however, refusing to let her move from her **** position. It won't be long now and you don't want anything to interrupt your breakneck pace.

“That's it!” You grunt, continuing to piston inside her until the last possible second, then slamming your cock as deep as you can **** it. Your cum pours out of you in a torrent, overwhelming your senses as you fill her ass with your seed.

It's not until the flow has finally begun to ebb that you feel your muscles burning with fatigue and realize that your body is covered in sweat. Pulling yourself out of Katie's abused backdoor, you see a quick flow of milky white sperm follow you out, leaking onto the bedsheet beneath you.

You collapse onto a pillow, your girlfriend following a few minutes later and snuggling up next to you.

“That was amazing.” She whispers in your ear, giving you a kiss. “You are amazing.” You try to respond, but exhaustion is swiftly overtaking you. A moment later, you are asleep.
