Fuck Emily on all fours

You've always liked to get it from behind and you know that Emily does too. There's something primal and intimate about the act, about your whole body shaking on your hands and knees with each thrust. If you're going to be fucking Emily, that's how you want to do it.

You don't speak to Emily, instead grabbing her body with both hands-- her skin feels wonderful-- and positioning her so that she's facing away from you. She quickly realizes what you have in mind, placing her elbows on the floor of Emily and Jordan's apartment and sticking her gorgeous rear end up into the air and toward you.

"Fuck me, Hayley," your best friend says, almost begging you. Dear God, you wish this strap-on were a real dick so you could feel the sensation of it inside her. Since it's not, this will have to do, won't it?

Kiera and Jordan move to the other side of you, sitting on the floor next to each other and facing you and Emily. Kiera looks shocked and amazed, but there's a cunning smile on Jordan's face. As always, she's in full control. Having your sister and her roommate watch you and Emily together is just one more thing that's made you dripping wet between your legs.

Gingerly, you place one hand on either side of Emily's hips. Her skin is electrifying. Emily coos when you touch her, pushing her body closer to you, and you angle the phallus as best you can to the lips of her pussy. Reaching down, you activate the vibration of the strap-on, causing it to buzz at the lowest level.

Emily turns her face back to you. With one hand, you slowly guide the tip of the dildo inside her; with the other, you grab her chin, bringing it closer to you so you can kiss her. The moment you slide the strap-on into her fully, your tongues are wrestling, and you realize you never want to stop fucking your best friend. Fucking her like you've always been fucked by a man is strange, but it feels good-- the buzzing against your clit brings you pleasure even as you thrust into Emily over and over. Your hand finds its way into her hair, pulling gently and then harder.

You watch as Kiera and Jordan's bodies slowly get tangled up into one another. Both sets of eyes are locked on you and Emily as you fuck her, but Kiera finds her way into Jordan's lap. Jordan has her hands between your sister's legs and her lips on Kiera's neck. Kiera's moans mingle with Emily's as you and Jordan pleasure your respective partners.

Watching Emily get sweaty as your strap-on slides in and out of her over and over is a sight that will be burned in your memory forever. She throws her head back, her eyes closed, her mouth open. Her moans come in short, curt gasps and high-pitched squeals, as well as longer breaths. Images of her naked body had always flashed in your head, but seeing it up close, seeing her locked in pleasure thanks to you, is something else entirely.
