PRED-457 The newly met girlfriend

My girlfriend and I have known each other for three months, today is the first time I have been to her house, I heard that her sister is also at home, so I thought I should greet her well to get a good impression. As she walked downstairs, I was almost paralyzed when I saw her braless breasts!! She was wearing only a flimsy shirt and I could almost see her nipples, it couldn't 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 with me at all, she accepted me, she allowed me to squeeze her big breasts, soothe my stiff cock, and even allowed me to have sex with her!! I couldn't keep my mind at all anymore and frantically fucked her even though my girlfriend was by my side...
