Vittoria Devine and Lu Roque, siblings with a secret passion, find themselves alone and horny. Vittoria, the seductress, lights a cigarette and takes a long, sensual drag. She watches Lu, her stepbrother, struggle with his erection, knowing she's the cause. She blows smoke rings, beckoning him closer. Lu, unable to resist, approaches. Vittoria guides his throbbing cock into her mouth, sucking him off while continuing to smoke. She teases him, pulling back to ash her cigarette, then resuming her blowjob. Lu fucks her face, his thrusts becoming more urgent. Vittoria moans around his cock, her pleasure evident. She pushes him back, climbs onto him, and rides him hard, their bodies slick with sweat and smoke.
