"I meant this, yes. Dealbreaker?"

"I... have never done that before, but I'm not a stranger to, er, being penetrated. So it's not a dealbreaker, no."

"Excellent." 

She disrobes and puts on the strap-on. Her skin is very pale. She gets out a bottle of lube and spreads it on her fingers, then strokes her faux-cock a little to spread the lube across it.

"So, shall we?"

Well this is going faster than she anticipated. 

"Uhm, I guess?" 

She undoes the clasp of her dress (she's got the hang of it now) and gets onto the bed. "How do you want me? On my back, on all fours... Riding you?"

"I'd like you on all fours, please."

Audrey gets down on all fours. 

Lily gets up behind her on the bed with a cleansing wand in one hand and a bottle of lube in the other. She taps Audrey's ass with the cleansing wand and sets it aside; then she spreads lube on her fingers and starts teasing apart Audrey's rosebud. 

Audrey is tense, but as Lily's fingers massage her backdoor she manages to relax a bit. Before long she's taking two of Lily's fingers easily.

"It's time to try and fit this in," says Lily. "Ready?"

"Mhm!"

Lily presses in her synthetic cock, and moans softly as it slips inside Audrey's well-lubed hole. She tries a few shallow thrusts, adding yet more lube from the squeeze-bottle in her hand.

Audrey shifts a little bit, adjusting the angle so that the strapon's grooved head presses into her prostate. She's done this before with her dildo enough to know what feels good.

Lily starts thrusting deeper, now, the grooved head of her dildo popping back and forth across Audrey's prostate, and its sensory feedback giving her the experience of fucking a tight, willing hole. Truly the best of both worlds.

Audrey mmmms appreciatively, and runs a hand through her pink hair to get it out of her face.

Lily reaches out and takes a close fistful of Audrey's hair. "Let's get serious," she says.

Her hips start bucking hard against Audrey's, her thrusts slapping against Audrey's ass.

Audrey lets out a moan and starts to drip on the bedsheets. The hand in her hair is hot as hell and the living presence of Lily's body behind and over her just makes her even more aroused. To say nothing of the pounding her prostate is getting right now. 

Lily means business. She redoubles her pace, tugging hard at Audrey's hair as her other hand steadies her side, fucking her down into the bedsheets.

It doesn't take long for Audrey to come.

And Lily isn't far behind.

"Hahhh, haaah, fuck, that was an experience."

"Glad you, mmm, liked it.~" Lily withdraws and pets Audrey's hair gently. "You were a very good girl."

Audrey flushes. "I, um, ah, thank you?"

"It's nothing." She steps out of bed and flicks the cleansing wand at the various messes. "See you around?"

Could you stay a while to chat?, she doesn't say. If she wanted to hang around she would be doing it.

"See you. Can I call you again?"

She discards the strapon and shrugs back into her dress. "Certainly," she says. And then she's out the door.
