You pull out.

You stop thrusting and enjoy Gabi's cunt massage your cock as she cums. When her orgasm finally subsides you unceremoniously pull out and shove your cock deep into her sister's equally tight, wet pussy.

"Goddamn," you grunt as you pound Rosa from behind.

"¡Oh Dios!" she cries repeatedly as her ass cheeks ripple violently from each thrust absorbed.

"Fuck my sister!" Gabi goads you. "Fuck her hard!"

After you bring Rosa to an orgasm, you reluctantly pull out with your cock slick with the juices of both girls. You still can't believe you're in a threesome with hot identical twins!

"You still didn't cum," Gabi frowns.

"God, I want to, sweetie, but I need to fuck you two again!"

"Yes, we need you to fuck us again!" Rosa giggles, shaking her ass at you teasingly.

You're faced with the same problem again of what to do with two pussies with just one cock?
