My timid stepsister, a virgin, requests me to initiate sexual intercourse and deposit my semen on her buttocks

I've been harboring a secret desire for my alluring stepsister, a Colombian goddess blessed with voluptuous curves and natural beauty. Her luscious assets and tantalizing derriere have always been irresistible to me. When we finally found ourselves alone, she surprised me by requesting to experience the pleasure of my manhood. While she's a virgin, her appetite for carnal knowledge was apparent. We began our intimate journey on the couch, her eagerly exploring my arousal, and me reciprocating by fondling her firm breasts. The climax saw me releasing my essence onto her round buttocks, marking her first taste of my seed. This amateur, homemade, interracial encounter was a testament to her insatiable sexual curiosity, leaving us both yearning for more.
