Sinning With My Sister: Chapter Four

Abella and Sara spent years trading orgasms between dorm sheets back in school. Sara texts—let's hang out tonight—and Abella's already housebound, waiting to smile through dinner for her parents' new foster kid. Then the car door opens and Tyler steps out: tall, brooding, six feet of pure trouble. Abella's throat goes dry. She fires off one message: New house rule—I'm fucking him before midnight. Sara types back one word: Same. Abella meets Tyler at the door. He offers the sad story, voice cracking, but she's staring at the outline in his jeans. Sara arrives, all smiles, offering drinks, blankets, whatever Tyler needs. Every brush of skin is deliberate, every compliment a dare. Tyler retreats to the bathroom to breathe; the girls steal glances through the crack and watch his cock bounce as he washes his hands. They seal the pact with tongues and spit. When he opens the door they’re locked in a filthy kiss. He bolts to his room, shuts the light, but the door handle still turns. Two silhouettes slide in naked. Abella peels his briefs down; Sara’s mouth is already on him, sucking loud, getting the shaft shiny for her friend. Tyler protests once, weak, while Abella climbs on and sinks slow, squeezing every inch until her clit kisses his pelvis. Sara settles on his face, grinding her shaved lips over his tongue until both girls shudder and come at once. Tyler's hips jerk despite himself. When Abella slides off, Sara takes her turn, smirking. "Your turn to fuck your sister's best friend." He stops fighting. Three bodies knot and sweat until Tyler pumps Sara full while Abella licks the spill off both of them.
