You came home early from college, your sister is so surprised to see you, the 2 of you have alot of catching up to do. She asks you about your new girlfriend. your sister hasnt had a boyfriend yet, she is focusing on good grades in university and feels like that would just side track her. She reminds you about how the 2 of you used to get in eachothers hair all the time, you used to bully her. You admit that you did that because you liked her more than what you actually should have. SHe finds it weird, you are brother and sister.. You find out that She is still a virgin and has only kissed a guy. You want to know if she is a good kisser, and she is.. You start asking more questions regarding her sex life, if she has ever had a guy go down on her.. you tempt her by telling her you want to show her how a guy should pleasure her one day. She is hesitant but decides that there is probably nothing wrong with only doing foreplay. you finger her and eat her out. She gives you a handjob and sucks you off. She wants your dick inside her. you fuck your virgin sister, she wants you to pull out, she can not risk falling pregnant.
