Jacob and Zach can take Emma if they use a condom

You tell the two guys that they can use Emma - give her a special birthday treat - if they use a condom. They agree to the terms and ask you for one, but you let them know you don't use them so you don't have any.

Zach and Jacob do paper scissor rock to see which of them has to run to the store. Zach loses and says he'll get condoms for all of you. His girlfriend, Sophia, pulls her head up from your cock long enough to tell her boyfriend, "You'll need Magnum plus sized for John, honey." He feels his own cock shrink a little when he hears this, but before he can reply she's already back to sucking your cock and so he just walks out.

Candice and Taylor switch places with each other and Emma has laid Zach down on the couch so he can eat her out while she throats his cock. This also blocks his view of you, Sophia, and Isabella - his girlfriend. So he doesn't say anything when you get up and proceed to start fucking his girlfriend bareback. Emma's thighs are even tight enough around his ears that he doesn't hear her call out your name while you fuck her sloppy wet pussy.

Then it's Sophia's turn and she briefly protested, "What about the condoms?" but you turn her around, push her over the back of the couch and penetrate her bareback while her cuckold boyfriend is out buying you an extra large condom.
