I got a big-breasted sex friend for the first time, so I tried playing with a perverted boob that I can't do with a girlfriend with small breasts

I love big boobs. But now she's a small titty girl. I actually want to play breastfeeding, lick her condensed breasts and rub her tied up big breasts all the time! That's how I got my first big-breasted sex friend. I'll do everything I've been embarrassed to ask her to do, or that my breasts are so small that I couldn't do it! Without worrying about rationality or appearance, we exposed our true nature just to satisfy each other's sexual preferences and sexual desires, and had a whole lot of fucking hard!
