My First Swallow: The Forbidden Night with My Sister-in-Law
It was 10 PM, Sunday night in our Nantes living room. Elisabeth had crashed early for her 5 AM shift. Laure, her sister fresh from La Baule, showered and slipped into that satin blue nightie. She plopped on the couch, legs up like a queen, thighs gleaming, spooning yogurt. I was in the armchair, half-watching 99 Francs, emails done. Heart already thumping from her flirty history—those poolside slips, towel teases, wedding night string flash. She’d spilled her secrets: doggy, anal now and then, bi-curious, that ‘dragon’ cum-nose story. Swallowing? Her thing. My fantasy. Never had it.
She laughed at the TV teen jerking to lingerie, then dog pics mid-spurt. ‘Ew, yogurt!’ I teased back, dropping her blowjob tale. Tension spiked. Cold stare. ‘Spit it out.’ I did. She defended: ‘That’s reward after he earned it.’ My cock twitched. ‘Lucky guy.’ ‘Not all girls do it.’ ‘Elisabeth won’t—even spit.’ Boom. Her shock. ‘Never? Poor you.’ Mock pity, eyes gleaming. ‘Drop your jeans; your lucky day.’ Joke? My frustration poured out: edging, tap shoulder, handjob finish. She countered vivid: jets hitting throat, swallow quick or dragon. Her wink. ‘If I’d met you first…’
The Approach
Frustration peaked. ‘You’re turning me on.’ ‘Door locked?’ Her leg caress. ‘Why wait?’ Challenge: ‘Fidèle? Coward?’ I stood, belt unbuckle bluff. She beckoned. Closer. Heart slamming ribs. ‘Show me.’ Pants down. Boxer bulge. Her eyes widen. ‘Elisabeth won’t like.’ ‘You started it.’ Tie. Her hand stops me. ‘Curious how much I turn you on.’ Boxer drops. Cock springs, semi-hard, 18cm throbbing under her gaze. Inches from her face. Pulse roaring. ‘Make it harder.’ Hand wraps my shaft. Stroke. No turning back. Nerves electric, desire drowning fear.
The Instant
Fist pumps slow. Eyes locked. Hard as steel in a minute. Her hand grazes tits, nipples poking satin. ‘Risking it all. Your turn.’ Grab her hand, guide strokes. Tight grip. Hips buck. ‘Gonna cum.’ ‘Already?’ Mock, but eyes wild. She leans, tongue flicks glans. Wet heat engulfs. Suction pulls, cheeks hollow, tongue swirls vein. New world—warm, slick, forbidden mouth owning me. Hands on her face. Thrusts build. Deeper. Gags soft. Eyes water. Can’t stop. Final brutal pumps. First jet blasts deep. She moans muffled. Hands grip mine, slow me. But I pump, unload rope after rope. Endless bliss. Throat works, swallowing.
Froze, cock pulsing in her mouth. She stares up, dazed joy. Caresses my hands, ass. Pulls off, hand catches drip, swallows. Pushes me gentle. Fixes hair. Whispers hot in ear: ‘You’re welcome.’ Sashays away. Door clicks. I stand shaky, spent. Hour to bed. Heart still races in memory. Innocence gone—first full suck, swallow by her. Wife’s sister. Line crossed. Man now, hooked on that rush. But tomorrow morning? That loomed darker.
