If I missed this opportunity, I would never be able to escape my virginity for the rest of my life. While I was wondering what to do, my sister offered to help me by... letting me practice fucking her!!! And then I was able to escape my virginity, her soft giant breasts rubbed against me, making my cock instantly erect, she sat on my cock, pushing it deep inside her, making me unable to bear it and quickly ejaculating inside her. This was supposed to be just for practice, but I couldn't stop anymore, I was addicted to the feeling of making love with her, I liked her and wanted her to be my woman...
