Your cousin Sophie

You look outside and see it's your cousin Sophie. She is two years older than you and have always been kind of a bitch to you. She is from the richer side of the family and learned early that money and beauty could get her almost anything she wanted. You took a look at her and she was indeed hot: blond hair done in a ponytail, slim waist, perky tits poking from under her shirt (Was she not wearing a bra?). And that lovely ass that inspired your dirty imagination for years was barely counseled under a miniskirt.

Sophie found you staring at her from the door. "Hey, John! Glad I found you home, mind if I come inside?"

Before you manage to answer she is already inside your house. Sophie asks your mother for a cup of water and when she leaves for the kitchen leaving you two alone, Sophie gush out:

"Hey, little cousin. You sure know why I'm here. I couldn't forget about all your perverted looks at my ass, you have been wanting to fuck me for years. Now is your chance!"

You smile at her. You indeed wanted to tap that ass for years, but should you go along with her pace or do something to take back control here?
