I had previously met my BF’s Graduated Frat Bro when I started dating my BF and he took me to parties hosted by him. In fact, he was (is?) my BF’s Big. I always thought he was cool. He was nice. Seemed to care about my BF and me. Just overall gave off nice older brother vibes.
Needless to say, I tend to show off my 36D/34DD tits whenever I go to college parties. So it isn’t uncommon to me to receive compliments on them from my BF’s tipsy/drunk frat bros. And even before I dated my BF’s I would get these compliments and I never minded them. In fact, I like the attention my tits get me. So when my BF’s Big (his name is Marty), would casually tell me my tits looked nice (always in front of my BF, he never made any inappropriate comments when my BF wasn’t around, nor did he do so anywhere that wasn’t a party), it didn’t seem odd or weird. I was used to getting that type of attention, specially at parties. And as I said, I actively enjoy the attention. The fact that it was coming from Marty was a little plus. I mean, he had similar features to my BF and a nice beard.
