Swipe the keycard at the roadside motel. Beep. Door clicks open. Dump my suitcase on the lumpy bed. Layover in this podunk rural town blows, but flight’s tomorrow. Spot the gym downstairs—town hall sports club hooked it up. Tight running shorts on, string underneath. Head down. Fluorescent buzz. Group of ten dudes lifting iron, pounding bags. Rivals banter, but chill. Youngest brings his sister. Cathy, 18. Stunning. Tanned fine face, emerald eyes, boyish short hair, wild gaze. Tight jeans hug insane bubble butt on her slim frame. Guys freeze. Awkward silence. She shakes hands mute. Dips into co-ed locker, we yield the john reluctantly. Emerges last. Red headband. White tank teases perky tits. Black cotton micro-shorts ride up, cheeks spilling out. Position center. Ten stares lock. I’m three-quarters back on treadmill. Eyes glue to that ass overhang. Instant hard-on. Cock throbs in tight shorts. Awkward jog. Mirror ahead, pray it fades. Nope. Rock hard, string no help. She eyes machines, heads my way. Spots bulge. Smirks, amused. Guys wink at her rear from behind. I stiffen more. She lingers. ‘Run long?’ Soft voice. ‘Nah, want it?’ Slow to walk, avoid nutting. ‘Keep going, I watch.’ Cock tents sideways. ‘Treadmill works wonders, huh? Supposed to slim ya.’ Bites lip, eyes dick. ‘Lose some, show me how?’ Stunned. ‘Show?’ ‘How to run, dummy! Need to drop weight.’ ‘Your ass? Perfect. Guys ogle since you walked in. You’re gorgeous.’ Blush. ‘You ogled?’ ‘Caused the storm in my shorts. Not gay.’ Laughs loud. All stare. I’m 27, flying high. ‘Calmed?’ Still bulging. ‘Fix in john if you wanna lift.’ ‘Hop on!’ She sways ass passing. Grabs my hand. ‘Stay, please. New to this.’ Total boner city. Guys envy-glare. Walk tandem. Frisk her shorts. Accelerates. Yips, I bump cock on ass top. Giggles. Runs cambered slow. Shorts wedge to thong. Pals pass: ‘Tandem or kiddie patrol, Pat?’ Laugh. She glares. ‘Guys right, I’m cramping.’ ‘Fuck it, I’m legal. Bang who I want!’ Softens. Smiles. ‘Stay, teach ass-slim run.’ ‘Keep ’em juicy.’ Smirk. Adjusts posture. Hand on cheek, tilts pelvis. Stays put. Power cuts. Dark. Crash into controls. Tumble. I cushion. Belly-down on belt. Cock jams her crotch. No move. Legs part. Grind harder. ‘OK, babe?’ ‘Yeah.’ Hand squeezes mine. Push dick on pussy. Fingers shift shorts, wet mound grinds cuissard. Tugs my waistband—lights flood. Scramble up. Pals awkward. ‘Bro fetched tools. Session dead.’ ‘Pat drives me home.’ Nods at me. ‘Yeah.’ Shorts fully wedged. Rental car. Heater blasts, she’s gym-clad. ‘Straight home?’ ‘Nah. Gurémy quarry? 20 mins.’ Tense drive. Directions only. Narrow dark lane. Kill engine. Dome light on. Stare windshield. ‘Now what?’ ‘What you want?’ ‘Suck you off?’ Laugh. ‘Direct!’ ‘Want?’ Cock surges. Camber hips. Shorts down. Dick springs. Gapes, laughs. Tongue laps shaft slow. Balls next. Minute tease. Reclines smiling, I’m steel. ‘Backseat? Gearshift digs.’ Giggle. Hop out, pants ankles. Rear seat sprawl. She four-paws, ass high. Licks balls. ‘Hard now, real fun.’ Gulp. Gland hits throat. Bobs deep. Ten strokes near edge. Clamp head, hold. Eyes up. Pace shifts: sloppy fast, slurpy slow. Caress neck, thrust mouth-dom. Quiet but wet sucks. Eye ass. Yank shorts deep wedgie. Giggles, twerks. Slap cheeks red. Fingers plunge soppy pussy. Finger-fuck as throat-fuck. Cum explodes. Bites light first spurt. Hold firm, churn hole. Gulps load. Lifts, sperm-smeared grin. ‘Fuck, massive! Like?’ Pose. Instant love. ‘French?’ ‘Nah.’ Scoops cum, swallows. ‘More gone. Tomorrow?’ Watch check. ‘Shit, 8! Parents kill. Drive!’ Drop block away. Kiss lips. ‘Wait.’ Shorts down, licks spent cock clean. ‘Goodbye style. Won’t forget.’ Dashes, jeans over shorts. Back to motel. Keycard swipe. Bag zip. Her taste lingers. Flight dawn. Perfect anonymous fuck.
