I wanted my younger brother's first time to be mine.<br /> Ever since I was little, I couldn't help but find my adorable little brother chasing after me, calling out, "Big sister! Big sister!"<br /> This older sister is so jealous of her younger brother's favorite AV actress that she interrupts him masturbating many times.<br /> During summer vacation in college, I had a fight with my boyfriend and I had nothing to do, so I went back to my parents' house...<br /> Oh, my younger brother has a girlfriend?! However, when I listened to his troubles, I found out that my brother was still a virgin. Apparently they haven't even kissed. I don't know how to create the right atmosphere.<br /> If so, I want to take your virginity... "I'll let you practice with me, Big Sister." Although I said it was for my brother's sake, I actually wanted his virginity.<br /> "It's hard to cum if I use a condom, so I'd rather do it raw." I wanted to give her a first experience that she would never forget. And even though they were brother and sister, he even came inside her...but it felt great.<br /> My little brother is climaxing inside my sister's vagina... He looks so comfortable... I became a woman that my younger brother would never forget.
