Finish her with the dildo.

You increase the pace of your thrusts, and Fiona clutches at the bedsheets, giving a short little cry. "Ah! .... ooooh, yeah, that's it, just like that ..."

She nudges her hips back toward your hand whenever you thrust into her, encouraging you, guiding your rhythm. Soon the bed is creaking with the motion of her body, and she's making quick grunts every time the dildo enters her.

"When you ... get ... hard ... again," she tells you, her voice made uneven by her exertion, "I'm ... ohh ... going to fuck ... you ... crosseyed ... oh, god ...."

She spreads her knees wider on the bed, burying her face in the mattress, half-smothering her moans and shouts. You're starting to feel a little dizzy yourself. You can't wait for the chance to get in her for real, to feel that tight cunt around your cock, to see the look on her face when you dive deep into her.

"Ohgod," she exclaims, the tone of her voice changing suddenly. Her hips start to quiver, and she braces herself. You know better than to stop now, so you keep up your rapid pace, thrusting the dildo into her quivering cunt, giving her stroke after stroke after stroke until...

Her head jerks up sharply, her hair flying, and her cry of release fills the room. You feel her cunt close around the dildo, almost snatching it from your grip, but you somehow keep hold of it, despite how slippery it's become. She shouts again, and again, every time you thrust into her, and only when her head starts to sag toward the mattress again do you start to slow your pace.

You downshift until you've returned to the slow, deliberate strokes you started with, and she rewards you with a long, happy, crooning moan. "If there is any justice in the world," she says, "please tell me you're hard and ready to get inside me."
