Emily accepts

Emily can't stop herself from cumming. Your fingers deep inside her and your lips on her skin drive her way over the edge, shuddering and convulsing around your fingers. Her eyes boggle and her mouth gasps for air, releasing a ****, violent moan.

Emily slumps back and your fingers slide out of her. Before she's fully recovered, you take the opportunity to lick your fingers clean, savouring the taste of your best friend.

"My dad's...?" she warbles. "Are you kidding?"

"No," you say. You follow her down to the floor, where her legs are already spread. Your fingers are inside her again, but you start sucking on her clit. Every once in a while you stop sucking to kiss Emily's pussy or to lick it. "If you play with us," you say. "We can all make you feel so good. Me, Natalie, Rainie, Kayla... even your dad. He thinks about you, you know. When he and your mother fuck. They fantasize about you."

The thought is clearly alien to her, but she's overcome every time she tries to speak by confusion and by pleasure. She squeals and groans and grinds her pussy against your face, eager for whatever pleasure you can give. "I'll do it!" she groans. "Please, I want it, please!"

Fantastic.
