You pull out.

You stop thrusting and enjoy Rosa'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 Gabi from behind.

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

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

After you bring Gabi 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 at the feeling of her pussy being empty of your cock.

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

"Yes, we need you to fuck us again!" Gabi giggles, reaching between her thighs to spread her wet pussy lips to tease you.

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