I never meant for it to happen, but once my husband walked in on me riding his best friend, everything cracked open. The slap of skin, the wet sounds of my cunt gripping that thick cock, my moans echoing off the walls—he froze in the doorway, eyes wide, and I came harder than I ever had with him. Shame flooded me the second it was over. I sobbed, begged, promised I'd do anything to fix it. He didn't leave, but he didn't touch me either. That silence pushed me straight into the arms of the one person who shouldn't have been there: my younger sister.
She'd always been the wild one, the one who fucked around and never got caught. When she showed up at the house a week later, I was a wreck—puffy-eyed, horny from neglect, dripping with guilt. We drank too much wine and I spilled everything. How I'd cheated, how I'd been caught, how the remorse made my pussy ache for something forbidden to punish me. She listened, then slid closer on the couch, her hand on my thigh. "Show me," she whispered. "Let me see what he saw."
Her fingers pushed under my skirt before I could stop her. I was soaked, clit swollen from days of denial. She rubbed me slow at first, dirty talk spilling out in that low voice of hers. "You dirty cheating slut. You let him fuck this married cunt raw and now you're dripping for your own sister." I should have shoved her away. Instead I spread my legs wider, hips bucking as two fingers sank into me. The guilt twisted into heat. I came fast, clenching around her, crying out apologies to a husband who wasn't there.
That night turned into weeks. Every time the remorse hit—when my husband looked at me with that hollow stare—I called her. We'd meet in the guest room, door locked, and fuck like animals.
She'd pin me down, tongue my asshole while I babbled about how sorry I was, how I deserved this filthy incest because I'd betrayed my vows. She'd laugh, spit on my hole, and work three fingers in while she ground her wet pussy against my thigh. "Tell me again," she'd demand. "Tell me how you got caught with cum leaking down your legs."
I did. Over and over. The words made me clench and squirt every time. She started bringing toys—thick straps she fucked me with from behind, making me watch in the mirror so I could see my remorseful face twisted in pleasure. "This is what happens to cheating wives," she'd grunt, pounding deep. "They end up taking their sister's cock because they can't stop being whores." I'd sob and come, promising I'd never cheat again, even as I begged for more.
One afternoon my husband came home early again. This time he didn't stop us. He stood there while my sister had me on all fours, strap buried to the hilt, my tits swinging as she railed me. The look in his eyes wasn't anger anymore. It was dark hunger. He unzipped, fed his cock into my mouth while she kept fucking me, and for the first time since the affair I felt whole. Remorse still burned, but it fueled the heat now. I sucked him sloppy, tears mixing with spit, while my sister whispered filthy praise about what a caught, remorseful, incestuous wife I'd become.
We didn't stop that day or the next. The three of us fell into a rhythm of punishment and pleasure—me on my knees apologizing with my mouth and cunt, them using me until the guilt blurred into raw, dripping need. I still feel the shame when I'm alone, but the second either of them touches me, it flips into the dirtiest satisfaction. Caught, remorseful, and deeper into forbidden sex than I ever imagined. And I wouldn't change a single filthy second.
