In a cramped bedroom, an amateur couple explores their boundaries. She's never taken a cock so big, but she's eager to try. He guides her head, teaching her to relax her throat, to take him deeper. She gags, chokes, but learns quickly, her eyes watering, mascara running. His cock swells, ready to burst. She looks up, ready, and he fucks her mouth hard, filling it with his load. She struggles, but swallows every drop, her chin glistening with excess cum.
