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