Sister Strap Sandwich

Casey Calvert and Keira Croft learn they're both fucking Zoe Sparx. Sisters share a look that turns bad fast. They don't break up with her though. Instead they hatch a trap. Keira phones Zoe. No mention of Casey on the line. Just sweet words, easy invitation. Zoe answers, all bright and ignorant. She drives over expecting a quiet fuck and walks straight into both sisters waiting. Surprise hits her like a slap. Mouth open. Eyes darting. She scrambles to say she didn't mean it, claims she loves them both, swears she got carried away. The step-sisters aren't buying soft talk. They strip off their pants, step into thick strap-ons, and order Zoe down on all fours. The first round is all bite. Keira slams into her from behind while Casey pushes the second silicone cock between her lips. Spit spills down Zoe's chin onto the floor. No more teasing. Hard thrusts from both ends bruise her knees red. Wet sounds slap and echo while the girls hiss that she belongs to them now, that she'll take every inch until she learns her lesson. Zoe moans around rubber cock. Her thighs shake but she pushes back for more. They rotate positions. Casey lies beneath her, pounding upward into a stretched cunt while Keira works in the back door. Two thick lengths crowd inside Zoe, sliding only a thin wall apart, splitting her open until her whole frame trembles. Sweat runs down her spine. The sisters slap her ass raw, call her greedy little slut, keep the pace mean. Hours later the room reeks of sex. Zoe can barely stand, cum dripping down her leg. She stares at them, sore, marked, unsure if trust can grow again but desperate to prove she means it. The sisters exchange one quiet glance, their faces unreadable.
