In the heat of the moment, Monica climbs onto Dylan's lap, her dress hiked up, revealing her soaking wet panties. She grinds her hips, rubbing her clit against his throbbing cock, moaning softly. Dylan, unable to resist, reaches around and pulls her panties aside, exposing her glistening pussy. He slips a finger inside, feeling her tight warmth. Monica gasps, 'Fuck me, Dylan. Make this our dirty little Valentine's secret.' She guides his cock to her entrance, and with one swift thrust, he's inside her, filling her completely. They fuck passionately, their bodies slick with sweat, until they both climax, their moans drowned out by the sound of their racing hearts.
