My 18-year-old stepsister's first anal experience with me while her mother is showering

It was a scorching summer afternoon when I found myself alone with my 18-year-old stepsister, Adoro. Her mother was in the shower, so we decided to make the most of our private moment. Adoro had always been a stunning girl, and I couldn't resist the allure of her shapely derriere. I took the opportunity to indulge in her luscious backside, exploring every inch of it with my mouth. She responded with a moan of pleasure, fueling my desire even further. I then turned my attention to her tight, inviting rear, eager to give her a taste of anal pleasure. Adoro was a bit apprehensive at first, but soon she was moaning in ecstasy as I filled her up with my throbbing member. As we reached our climax, I released my seed deep inside her, leaving her wanting more of my hot, tasty cum. It was a day of pure passion and unforgettable anal sex with my stepsister.
