So a chick asked me out

I've been dating 2 of my cousins for a year now without each other knowing. I fuck both of them all the time. But, a girl asked me out today at school. I've been going to university for 3 years now. There's a cute chick that's been eyeballing me for a while. Now, I love fucking my cousins but realistically, I know I have to settle down with someone that actually isn't related to me(gasp)
The type of girl I want has blonde hair, thick body, decent sized tits, great, meaty ass, etc. the chick that asked me out only has the ass. She has brown hair but she's so adorable. Her name is Veda. She is a bit of a goofball but she's so hot too. She asked if we could go out to the movies or something. I told her yes. I don't want to screw this up, since she's actually a good girl for me. She doesn't drink, or fuck for no reason, she doesn't do drugs, she's actually a good chick. I've had my eyes on her since she is a cheerleader. I want her. I'm going have to break up with both of my cousins
