My adult childhood friend Saki suddenly calls me over, and I hope she is about to confess her love. Instead, she happily announces that she has a boyfriend, crushing me after years of secretly loving her. Then she asks for a once-in-a-lifetime favor: she wants to practice sex with me so her boyfriend will not think she is bad in bed. She insists this is only practice and orders me not to take liberties, but I see my chance to kiss her, make her suck me, and fuck her untouched body before her boyfriend can. I plan to steal her away with my cock and make her unable to live without me.
