I convinced my step-sister to give me oral sex and had anal intercourse with her

I've been harboring a secret desire for my girlfriend's sister. A few days ago, I finally mustered up the courage to act on it. I lured her into my room with the promise of a movie night, and when she was alone, I unleashed my lustful intentions. She initially reacted with shock, but soon succumbed to my seduction. I lavished her with sensual kisses, exploring her body with my hands. She eagerly reciprocated, unzipping my pants and taking me in her mouth. The intensity escalated as we moved to the bedroom, where she assumed the doggy style position, ready for a wild ride. I plunged into her, savoring the passionate encounter. Our fervor only intensified as we transitioned to anal sex, cementing our taboo tryst. The climax was explosive, leaving us both breathless and satisfied.
