It's time to start fucking

Both couples transition to fucking after Isabella's loud orgasm subsides.

As you fuck Isabella keeps telling you how big you are and you tell her to say it louder, and much to her boyfriend's chagrin she does what you say.

You do the same with her tits, loudly expressing your love for them. Your Emma feels shame that you're doing this, but that shame makes her want you even more. Despite Jacob fucking her - she's still focused on you.

Emma made Jacob wrap up his weiner in a condom and he assumes you've done the same with yours. But Isabella didn't even think about needing protection, she was too eager to get your massive cock inside of her.

Emma and Jacob are fucking missionary when she tells him she wants him to take her doggy-style. This really excites him, and he's happy to get into position. He doesn't realize it's so she (and he) can now watch you and Isabella better.

You and Isabella are going at it with gusto. She loves the attention you're giving her big tits - she can see the delight in your eyes. Isabella looks over and see's Emma on her hands ad knees and she barely has any tits hanging down at all. When Isabella is taken from behind her tits hang down like udders and shake almost violently. You're a poor boy, Isabella thinks, to not have a good pair of tits to play with. Given how well-endowed you are, Isabella thinks you deserve better than Emma's basically flat chest.

Isabella's a bit of a slut, but her pussy is still very tight on your cock simply because your dick is the largest thing that's ever been inside her. You're thicker than any toy or dick that's penetrated her - by a long shot really. Fortunately Isabella is well-lubed from being so turned on, so despite the **** tightness, you're sliding in and out of her with silky ease.

After shifting positions a few times, you and Isabella bring each other to synchronized orgasm. As you approach your climaxes you both moan and scream and claw and grab at each other's sweaty flesh. You push hard into each other - thrusting violently deep into Isabella's womb until you both cry out in pleasure.

Your cock spasms inside of Isabella's quivering unprotected vagina in a torrent of thick, creamy cum. The sensation of being filled to the brim with semen is delightful for Isabella, who is used to Jacob pulling out and having his load spurt onto tummy. Her body is shaking as her orgasm continues long after the flow of your cum has stopped flowing.
