Tan lines fading into wetness where the bikini bottoms should be. That’s all you catch through the doorway—her ass hovering over his cock, thighs trembling like she’s pretending not to notice someone peeking. Fingers tangled in sheets, nails digging in when he thrusts up too hard. Mouth open but silent, eyes half-lidded like she knows this isn’t right but can’t stop. Cum drips down her inner thigh and she wipes it slow, deliberate—like marking territory.
