PRED-457 new girlfriend

My girlfriend and I have been dating for three months, today is the first time I went to her house, I heard that her sister was also home so I thought I had to greet her well to make a good impression. When she came down from upstairs, I was almost shocked when I saw her braless chest!!! She was only wearing a thin shirt and I could almost see her nipples, it could not hide her charm at all!!! I couldn't resist such big breasts so I subconsciously approached and touched her. But she didn't get angry at me, she accepted me, she let me squeeze her big breasts, soothed my stiff cock, and even let me make love to her!!! I completely lost my mind and madly made love to her despite my girlfriend being right next to me...
