I wanted my brother's first time to be mine. Ever since I was little, I couldn't help but think that my little brother was so cute when he would run after me and say, "Onee-chan! Onee-chan!" She is a big sister who likes her younger brother so much that she gets jealous of her younger brother's favorite AV actress and interrupts his masturbation many times. During the summer vacation of college, I had a fight with my boyfriend and had nothing to do, so I went back to my parents' house and... Oh, my brother has a girlfriend! ? However, when I asked him about his troubles, he discovered that his younger brother was still a virgin. Apparently they haven't even kissed. I don't know how to create an atmosphere. If that's the case, I want to take that virginity away... ``Sister, why don't you use me as a practice table?'' I said as if it was for my younger brother, but I wanted his younger brother's virginity. ``If you use a rubber band, it will be difficult to cum, so it's okay to cum raw.'' I wanted to give her a first experience she'll never forget. And even though they were siblings, they even had to cum...but it felt great. My brother is reaching his climax inside my sister's vagina... She looks like she's feeling great... I've become a 'woman' that my brother will never forget.
