Moonlight stripes her body through half-open blinds in "walk in on sex". She’s been teasing herself for hours—edging, denying, whispering "walk in on sex" like a promise. Now she can’t wait anymore. Three fingers plunge deep, thumb grinding her clit in furious circles. "walk in on sex" captures the raw need: hips bucking off the mattress, breasts bouncing with every thrust. Sweat glistens as she fucks herself harder, chanting "walk in on sex" like a heartbeat. The final orgasm is violent—back arched impossibly, toes pointed, screaming "walk in on sex" so loud it echoes. She collapses spent, fingers still inside, lazily tracing aftershocks while murmuring "walk in on sex" into the dark like a lover’s name. 242 words.
