When a college teacher invites her student for extra classes at her place that means she wants something more than just to teach him math or something....
Imagine you come home and see your girlfriend making out with her female friend, would it make you angry or hot? Well, anyway if they invite you to join them, you better agree, cause theres probably not going to be a second chance
You meet a girl at the party and you dont know her at all but you can feel the desire overtaking you, you wanna be with her, you want her pussy, her flesh and theres nothing you can do about it!
