Woman lying on her back in missionary position on a massage table in a cozy spa room with dim candlelight, essential oils bottles nearby, towels draped around, her nude athletic body glistening with massage oil, sweat beads forming on her skin, long dark hair spread out, eyes half-closed in ecstasy, mouth slightly open moaning softly, legs widely spread and wrapped around the man on top, knees bent for deep access, one tall muscular man with defined abs and veiny arms positioned on top of her, his thick erect penis fully inserted into her vagina, thrusting deeply and rhythmically with hips grinding against hers, his hands gripping her hips tightly, their faces close with intense eye contact and passionate kisses, another equally muscular man kneeling or positioned slightly to the side behind her raised hips, his large erect penis penetrating her tight anus from a angled position for double penetration, sliding in and out slowly at first then building intensity, all participants completely naked with oiled skin shining under the light, realistic details including visible arousal like erect nipples, swollen labia, pre-cum dripping, veins bulging on penises, muscles tensing during thrusts, bodies slapping together with wet sounds implied, expressions of overwhelming pleasure and raw passion on faces—her back arched in bliss, men grunting with desire, high resolution 4K, ultra-detailed textures on skin pores, oil sheen, and intimate connections, erotic atmosphere emphasizing sensations of fullness, stretching, and shared intimacy in a forbidden threesome scenario
