I've been dating my boyfriend for 2 years, and we've moved in with his older brother, his girlfriend, and his younger sister. I am a very quiet guy, and my boyfriend is very talkative. When we first arrived, he instantly became close with his brother's girlfriend, Anna. He is a very talkative guy, and willing to try anything. He is very personable, so in most situations, I fall into the background. This is the same boyfriend with the large penis I talked about in my other threads; well, it was hinted that his brother shares the same gift, by Anna. My boyfriend chimes in "Must be a family thing." Letting Anna know he is well-endowed too, if indirect. Since then, I've noticed her glances towards his private area if he's wearing anything like pajamas... or tight jeans. He says she isn't doing it, but I know what I'm seeing. What do I do? I don't think my boyfriend is going to cheat on me with Anna (even if he recently admitting to experimenting with girls when he was younger, after denying it for the first year...) but it's uncomfortable for me to witness this. I've started to grow an animosity towards Anna for this... It's weird because she's dating his older brother... I can't confront her, because I am living with her... and I can't discuss it with him (I tried) because he will likelt bring it up to her. Any suggestions???
