A Double Ended Strap On

Moaning in delight Mars inserted the double-ended strap on into her. Pausing for a moment to adjust to the feel of the alien toy she now wore before moving Crystal out of the way.

Cherish was so absorbed in trying to milk cum from Tristan she hardly paid any heed to the switch of a tongue lapping at her, a hand blindly reaching to bring Mars’s head back into place pausing as she felt the tip of the toy teasing her slit.

“Mmm.. Yes...” Cherish mindlessly moaned barely sparing a glance at who, or what was penetrating into her.

Flexing her hips as she tried to sync with her sister’s maiden use of the strap on, Cherish was oblivious to the sensations and pleasure bombarding her twin. Mars delighting at the new perverse experience and toy, Crystal pressed up behind her, grinding her body against Mars.

“Do you know what I love most about this ****?” Crystal’s husky voice asked rhetorically as her tongue and lips teased Mars’s ear, hands squeezing and tweaking the flat-chested girl's nipples. “The way it cuts away the veneer of what we purport to be, freeing us to just pursue wild, animalistic, pleasures.”

Relishing the sensation of the toy as it shifted within her with each thrust, Mars loved the look of her sister’s body shifting and squirming, Mars's pale flat chest flush with blushing. Crystal’s words resonated in Mars, as Crystal's lips nibbled down along Mars’s neck between added whispered words of how hot she was finding the sister’s taboo corrupt sex acts.

“I’m getting off just watching you play with her. Surprised you haven’t already laid yourself across her, competing for when Tristan cums next.” Crystal suggested a hand groping one of Mars’s ass cheeks as Crystal moaned at the idea of her next perverse act. “All the while, I can shift that strap on's thong over and eat your ass. Preparing you for Tristan to fuck her, through you.”

The words drove Mars into an excited frenzy, Cherish sister spasming in pleasure releasing the cock from her mouth as the toy shifted its angle of penetration.

“OH FUCK…” Cherish cried out in pleasure as she glimpsed what she already knew to be true, the revelation that her sister had already helped push her to new sexual heights of pleasure, and new depths of perverse depravity imprinting heavily on her broken will.

Mars fondled and teased Cherish’s nipples, her lips engaging in a sloppy **** of wet kisses across Cherish’s chin and face before their tongues tangled for a moment.

“Cum on us both.” Mars lewdly asserted staring up at Tristan as his cock reflexively spurted ropes of cum onto the twins faces to which they responded with a ballet of tongues while Mars continued gently fucking Cherish, moaning softly in response to the tongue at her ass and the finger delicately trying to worm its way in.

“We are going to get so fucked.” Mars declared to her sister lewdly, exchanging an intense sexually charged stare before mouthing the miraculously still rigid cock hanging by both her and Cherish’s faces.

“I need more…” Cherish moaned softly, pleadingly between mouthing parts of the exposed cock, somehow innately knowing Mars already understood this fact.

Understood it, and embraced it better than Cherish had been prepared for.

As the cock pulled away Mars chuckled at Cherish. “The whole reason I started fucking you with this toy is…” The proclamation was cut short with a wide-eyed gasp. A long drawn out uneven moan following as Mars remembered why she didn’t do anal.

The overly intense pain somehow euphoric under the **** influence, allowing Mars to finally understand what some girls preferred about the sensation.

“He has to fuck me before he can fuck you!” Mars’s completed the sentence, driving another climactic spike in the ridged toy she was sawing in and out of Cherish, as the pace, angle and pressure of the toys shifted once again as Tristan’s slowly increasing thrust made room for more cock in Mars’s ass.

Cherish pulled Mars into an intense tongue tangling kiss, holding her identical twins mirror visage close to her face as they each breathed heavily upon one another.

“You bitch… Anything… To be… first…” Cherish moaned up into her sister’s face.

“Fuck ‘em harder Tristan.” Crystal moaned, legs spread fingering herself off to the side. “CUM IN HER!” Crystal demanded, fingering herself closer to squirting in orgasmic bliss as she thought of what other positions they could all try. “Cum in there so I can lick it out!” Crystal cried out, the perverse new depraved idea conjuring the final nudge in pushing her over into another climax.

Screaming out in pleasure Crystal soon found her voice joined by three others. A long pause in movement as the still suspense of heavy breaths slowly dispersed as the bodies pulled apart. Tristan staggering over to sit in the chair where he had first been blown by Crystal.

Mars pulling the toy out of Cherish before rolling over to lay on the couch next to her. Crystal breathing heavily gazing around wondering, if any of them were truly done yet.
