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