Want to sleep with her

Hii I m 22(M) and there is a girl in my college who is 19(F). She is my junior. We r friends. She gives me to come close to her , to touch her waist , to touch her hand and whenever I ask her what we r see always say she we r just friend.

Now I want to go one step ahead with her , I want to sleep with her.

Can anybody tell me how can I make her sleep with me
