With conditions

“Is this what you wanted Flis, is this what you need? To get fingered by some stranger, with your parents just the other side of that door, with people who think you’re such a polite and respectful young lady chatting to them so close. How shocked would they be to see you now, naked, getting groped like a dirty little slut”?

His voice is right in her ear, his words so clear even as she gasps and moans and presses herself back against him, feeling his hard cock right there, just the material of his trousers between them.

“Say it Flis, say you’re a dirty little slut who likes to get fingered and groped by strangers.” His words are urgent, matching the pace of her moans. She is wordless, but he is insistent. “Say it, say it, you dirty fucking slut."

His fingers are working her all the time, two inside her, his thumb on her clit, his other hand around her, holding her firmly as she tries to stifle the cries that she knows are always close at hand when she cums.

“I won’t let you cum until you admit it Flis, admit what you are.” She realises he means it, that somehow he will deny her the release she needs so desperately, and she knows she can only do one thing to achieve it.

“Yes, I admit it, I’m a slut, a dirty little slut. Fuck, I need it so badly, I want your cock.” The words slip out almost against her will, somewhere deep in her mind she remembers him saying she would beg him to fuck her, and now she realises she has done just that.

“Oh you good little girl, You have my permission to cum then” he whispers it so softly she hardly hears him over the loud beating of her heart. But her mind registers the words, the permission, and she has to bite down on her lip suddenly to muffle the scream of pleasure that she wants to give. Her body shakes, her legs buckle under her as an orgasmic tidal wave washes over her, crashing through her whole body the instance he said she could cum.
