Is it normal that i fantasize about my boyfriend's (younger) brother?
I noticed that lately Ive been fantasizing about all the stuff my and my boyfriend do/ would like to do and then think about adding his younger brother into the mix. Kinda like a threesome but with things like bondage. I haven't really told my boyfriend for the obvious but the thoughts have become more persistent and when I do think about it, I uncontrollably smile and blush. IIN?
