She has been getting REALLY horny after the past few days and we were kind of screwing around talking back and forth and i asked her if she would dance with me. And she's like yeah. But then she asked me something that completely caught me off guard. She goes. Be honest. Do you look at my ass? And it completely caught me off guard. And so i said yea. All the time. I almost fell off the stairs once tryna turn around so i can see your ass. Long story short we really really get into it and she's like we should have sex. And im like woooooaaaahhhhh. Honestly im not a virgin but i havent had a lot of experience and i dont know how to "do" her if you will. And i dont have a car at the moment neither does she. I have like a 2 hr window before my parents get home. I really like this girl and i dont want to fuck it up. Please give some advice.
