This is the first time I have a girlfriend, she is in the next class and also the person I have unrequited love for a long time. I am going through a happy but extremely confusing time. She wants to have sex with me!!! I know she had a boyfriend before, although I don't know if she has had sex before, but I am not confident in myself. If I cannot satisfy her, she will criticize me and leave me. If I miss this opportunity, I will never be able to escape the life of a virgin. Not knowing what to do, my sister offered to help me by... letting me practice with her!!! And then I was able to escape the life of a virgin, her huge soft breasts rubbing against me made my penis immediately erect, she sat on top of my penis, inserted it deep inside her, making me unable to bear it and quickly ejaculated inside her. Originally, this was just for practice for me, but I couldn't stop, I am addicted to the feeling of having sex with her, I like her and want her to become my woman...
