My girlfriend's brother spent the night with me one night when we were drinking and watching porn movies. We both got super turned on and he said, "Man, I wish someone would get me off tonight." I said, kind of joking, "There's no one here but me and you, so that would have to be me." He grinned and said, "Okay." I was drunk enough to take him up on it. We had a great time and I really enjoyed it. He spends the night with me once or twice a week now and we've graduated from me giving him oral sex to him using me like a girl in every way. So now I'm my girlfriend's brother's bi-sexual boy-toy.
