My sister had a condom she got in a health and physical education class and said "Let me practice with you, big brother," so I couldn't refuse and just helped her out. Just when I thought I had successfully put it on, my sister's behavior suddenly changed! She straddled me and said, "I used birth control properly, so it's okay to have sex, right?" But it broke in the middle and we were raw! And my sister felt even more, so I came right out. My sister and I did it raw again... this is unavoidable, right? My sister wanted to do it!
