Keep going

You're enjoying this too much to stop so you just keep at it and not even a minute later you grunt "I'm cumming....!" She looks back in surprise and just says "Yes!"

Your dick starts exploding as you keep fucking her as hard as you can. Each thrust feels like you cock head is shooting off and you start to slow down. It feels like your orgasm just keeps going though, so you keep pumping. You don't stop until you're completely spent and she's filled up.

"Wow, oh my god, uh, whew..." you finally let out.

"That seemed pretty good," she says as she looks between her legs, "don't think I could take any more!"

"I'd be willing to try," you retort, smirking.

"Not right now, babe. I think we need a break. Plus, there's birthday cupcakes to finish and eat!"
