Tell her to stop.

As amazing as her mouth feels on your cock you need to fuck her tight hole. You flip her on her back and barry your tongue into her cunt making her squeal and moan like a whore. You lap up her pussy juice like its milk and then kiss her with it. She seems to like this because she uses her tongue to get every drop from your mouth. Then you put her on all fours and ram your dick into her tight hole. You moan out in ecstasy her hole is so tight and so wet.

"Kelly I want you to cum every sixty seconds until I tell you not to."

She nods her head as another orgasm rips into her. You slam into her pussy fast and hard getting her wetter and making every orgasm more and more intense. You don't last as long as you would like because of Kelly's oral skills but as you feel your self getting ready to cum you start fucking her at a savage pace going faster and harder then you knew was even possible until you empty three huge loads deep inside her pussy.

You fall back on your bed and she falls on top of you similarly exhausted. You remember to tell her to stop cumming to give her a break. Then you wrap her in your arms and lay her on your chest with your dick rubbing against her cunt. You can’t wait for Zack to come back and find the two of you like this. Oh the fun you will have with second huge dick to play with.
