I showed up at my wife's family reunion already half-hard from the texts. Her younger sister, Megan, had been sending me pictures all week—her tits pushed together in a low-cut top, her ass bent over in the mirror with the caption "Can't wait to see you, big brother." We had been sneaking around for months, ever since that drunken night after their parents' anniversary when she grabbed my cock under the table and whispered that she wanted it raw.
The house was packed. My wife, Lisa, was busy with her mom in the kitchen. Megan caught my eye from across the living room and licked her lips. She wore a tiny sundress that barely covered her ass. No bra. Her nipples poked hard through the fabric. I excused myself to the basement "to grab more beer" and she followed two minutes later.
The second the door clicked shut she dropped to her knees. "I've been wet all fucking day thinking about this," she said, yanking my zipper down. My cock sprang out and she swallowed it in one greedy gulp. No teasing. She sucked like she was starving, spit running down her chin, gagging herself on purpose so the wet sounds echoed off the concrete walls. I grabbed her hair and fucked her throat hard, balls slapping her chin.
"Get up," I growled. I spun her around, bent her over the old pool table, and flipped that dress up. No panties. Her pussy was shaved smooth and already dripping. I slammed into her in one thrust. She moaned loud enough that someone upstairs might hear, but neither of us cared. I pounded her cunt like I owned it, the table creaking under us. Her tits spilled out the top of the dress and I reached around to pinch her nipples while I railed her.
"Fuck your sister-in-law," she panted. "Fill that married pussy with your cum." I slapped her ass red and drove deeper, bottoming out on every stroke. She came first, legs shaking, cunt squeezing my cock like a fist.
I didn't stop. I kept fucking her through it until I felt my balls tighten. I pulled out at the last second and painted her ass and lower back with thick ropes of cum.
We cleaned up fast but the risk only made us hornier. Later that night, after everyone passed out from drinking, she texted me from the guest room. I slipped in and found her naked on the bed, legs spread, two fingers buried in her pussy.
"Get over here and fuck me properly," she ordered. This time I took my time. I ate her out first, tongue fucking her hole while she ground on my face and whispered filthy shit about how much better I was than her sister's husband. When she came on my tongue I flipped her onto her stomach and mounted her again. I fucked her slow and deep at first, then hard and fast, the headboard knocking the wall. She reached back and spread her ass cheeks so I could watch my cock disappear into her.
"Want it in my ass?" she asked. I didn't answer with words. I spat on her hole, worked two fingers in, then lined my cock up and pushed inside. She hissed and pushed back until I was balls-deep in her tight ass. I fucked her ass raw while she rubbed her clit, both of us grunting like animals. When I came I stayed buried, pumping load after load into her guts.
We kept it going all weekend. Quickies in the laundry room, her sucking me off behind the garage while the family barbecued, me fingering her under the dinner table. By Sunday night we were both sore and marked up with hickeys and bite marks.
Before I left she cornered me in the hallway. "Next time Lisa goes out of town, you're coming over and we're not leaving the bed. I want you to fuck every hole until I can't walk." I kissed her hard, grabbed her ass, and told her to keep that pussy ready.
She always does.
