I am dating a girl who is not very beautiful but is a very good person. Today is the first time I visited my girlfriend's house, and she introduced me to her sister, Irita. Irita is extremely beautiful, with a perfect figure, and an H-cup breasts that I can't take my eyes off! This time my girlfriend went on a trip with friends, and I suddenly remembered that I had forgotten something, so I went to meet her sister. To my surprise, she attacked me with her braless H-cup breasts! I couldn't resist this deadly charm, and from then on we secretly had sex continuously, even when my girlfriend was right beside us...
