Sophia motions for you to get behind her

You're making eyes with Sophia when she cocks her head back to indicate to you, you can tell, that maybe you want to try getting behind her. You contemplate Sophia's proposal while she continues to fuck your cock sucking sex **** girlfriend. You only live once, you think, so you rip your cock out of Emma's hungry throat and climb on the couch behind Sophia.

Sophia leaned over more over Emma, who is on her hands and knees, you spit a generous amount on your cock, and without looking too closely at where it was going, you press your cock into Sophia - specifically you press your cock against Sophia's very tight asshole. You push forward and your cock wins out against the asshole and you inch deeper inside as you slowly build up your thrusts.

You've fantasized about fucking Sophia in the ass plenty of times - it's been a fairly routine fantasy you have to admit - but you never imagined it would be like this - that you'd be fucking her ass while her cock was inside of your girlfriend.

It's hard for Sophia to keep her thrusting going sandwiched between you and Emma, but your cock is pleasuring her g-spot so she has no trouble keeping her cock rock hard despite this.
