Fuck her pussy

You rub your strap-on dick up against the lips of her pussy, running your hands along the sides of her legs. "I'm going to give you what you deserve," you promise.

Jordan grins. "Alright," she says. "You know, I've never gotten fucked by this thing before."

"I hope you have a good first time," you say as you slide it into her pussy.

She groans, and you see her hand clench on your sister's ass, waking her suddenly. "Hayley!" your sister exclaims.

"It's okay, Kiera," you say. Your right hand leaves Jordan's thigh to rub your sister's knee tenderly. "I'm right here. Everything is okay."

Jordan is groaning, her head rolling back into the pillow. She's muttering to herself, too quiet for you to hear.

"Kiss her," you suggest to your sister. "Her neck."

Kiera does, moving over in the bed to leave little red marks on her roommate's neck.

"Fuck," Jordan says. "God, the Becks know how to make them."

You reach under Jordan to grab her by the ass, holding her hips slightly in the air as you thrust into her. The motion is foreign to you, and a little bit strange; the signals in your head are telling you that your body wasn't meant to move this way. But you've been fucked by guys before, you've watched plenty of porn. You've watched how their hips move. It might be a little amateur, but you can mimic it well enough.

"The vibration," Jordan gasps. She stretches her long body, pressing the palms of her hands against yours to keep them in place. "Turn on the vibration."

You fumble around the strap-on with one hand until you find the button at the bottom. You shift through the settings until you reach the fifth, the one you remember being most comfortable. Any higher than that would be too intense, you think.

Your sister is rubbing Jordan's clit with one hand and running her hand through her roommate's long hair with the other. She isn't giving Jordan the chance to groan, smothering her sounds by making out with her. Before this week, you might never have thought that seeing your sister and her roommate together would make you so wet, but it does.

Thankfully Jordan isn't the only one receiving pleasure from the vibrating strap-on. The back end of the phallus, the flat side, is pressing against your own clit. The buzzing is less intense on your end, but it's pleasurable, and when it's combined with the image of Kiera and Jordan together, you find yourself more than satisfied.

Together, you and Kiera overwhelm Jordan. The tall woman can barely move with you holding her hips tight and with your sister's body almost entirely on top of hers. By the looks of it, though, it seems that she doesn't mind being trapped. Her muscles tense up and relax at different intervals, some groans escape her mouth even with Kiera kissing her.

You feel the spasms begin slowly, Jordan grinding her hips against your dildo at first. Then her hips start to shake, and her hands tremble against yours. Her whole body heaves, and Kiera is almost bucked off. Your sister jumps back, keeping her hand on Jordan's clit, looking her in the eye as her roommate is overwhelmed by orgasm.

The orgasm finally subsides and Jordan lies back on her pillow, sweaty, drained, and exhausted. "Wow," she says, voice cracking. "So... is this going to be a regular thing...?"
