Wanting to fuck my Flatmate

I have a long time flat mate and she is my friend, but time flies, I really wanted to peep and fuck her. I started checking her panties whenever she is out for work and I felt like wanting to fuck her more.

I am planning to peep her, she's hot and her tits are great. One time, she dressed like she wanted me to see her tits from the side her dress, It just so happened that her Bf was there and i told her, "I already saw your armpits and side tits" , and she just stared at me.

I guess, she wanted me to see it. what do you think guys?
