My older brother is visiting from college while our parents are out of town for the weekend.. He had much more in mind for his weekend with me than just spending time together. He takes it upon himself to teach me all about sex, and boys, because he is ashamed that I am 18 years old and still a virgin. I completely trust my older brother, and know he wants what's best for me, but I still feel like the whole weekend was wrong. First he shows me porn, and how to masturbate... Then tries to feel me up during a massage.. Then we play truth or dare and he keeps daring me to take clothes off and touch him.. Eventually he dares me to put my mouth on his dick, and actually dares me to let him fuck me. I'm really glad that he told me having sex with him doesn't count as losing my virginity... I really want to save myself for the right guy. I do hope him eating his cum out of me keeps me from getting pregnant though.... I am kind of worried.
