I have passionate sex with my timid sister and prove my heterosexuality by ejaculating in her anus.

In my humble abode, I've been harboring a burning desire for my sister. Her tantalizing curves and alluring physique have been a constant source of temptation. The thought of her luscious breasts and ample derriere has been playing on my mind, fueling my primal urges. As a young man exploring his sexuality, I've been labeled as a homosexual by my peers. But I'm here to prove them wrong. I'm a proud heterosexual, and I'm going to show it. I'm going to take my sister, the one I've been craving, and make love to her in the most intimate way possible. I'm going to penetrate her tight, inviting anus, filling it with my throbbing desire. And as I reach my climax, I'll release my hot load deep into her welcoming rear. This is my coming out, my declaration of heterosexuality. This is my passion, my love, and my desire. This is my sister, my muse, and my everything.
