Inside her

You ram your dick inside her as the other guy does the same as her pussy spasms in orgasm. The other guy fires his load, covering your dick in his warm spunk, which sets you off as you cum, spurting your cum inside her. You both pop your cum-covered dick out of her as cum dribbles out of her pussy slowly. She groans as the others all finish cumming inside her as well.

You quickly wipe off your cocks, standing over the exhausted, cum-covered prostitute, unsure of what to do next.

"Do we go?" someone asks.

"Yeah," Lukas says.

"Thanks for this," Daniel says. "I appreciated it."

"Yeah, thanks," Lukas says. "Although it is admittedly a bit weird. Is it OK if we just don't talk about how we kind of fucked each other? Dicks were touching there."

"Uh... yeah, you're welcome and that, but let's avoid mentioning this. Let's get the fuck out of here," you say.
