That is a hard question! A nice ass is hard to beat but nice round breast and perky nipples are absolutely incredible as well. I guess a nice ass if I had to pick one.
That is pretty much impossible to choose one or the other. Both the start and finish line are part of that course.
I love big tits! Nothing better than burying my face in a pair of big ol' titties. The feel, the smell, it is just the best.
I definitely start with the ass. I like it firm and slightly rounded. I have a strong attraction to fit women. I look at the tits next. Athletic fit women typically have small tits and that is what turns me on. C, B, A cup or smaller in a sports top/bra is a huge turn on for me.
In everyday life with their clothes on, especially if a woman's breasts are covered, it's her ass, and in particular a tiny ass, with no hips, that attracts me most (after her pretty face first). But if she's showing cleavage with C sized breasts, then that's the first thing I see and glue my eyeballs too. Being naked with my girlfriend when we were going out, who had absolutely perfect D sized breasts on a yoga teacher's body, I totally became a breast man, and now include enjoying large breasts on women when I see them on the street. But in porn, pictures or videos, it's equally A-D breasts and small asses that give me that deep cut. But after my girlfriend and I started anal, both of us giving and receiving, and my enjoying anal with guys so much, I now love the female asshole in the porn world so much too.
What completes a woman? If she has big boobs people will stare at her if she has a nice round ass people with stare at her. I would say you need both. I definitely a fan of both. Can't have one without the other.
I love Boobs. To me a nice size pair make a woman a woman. I especially love large diameter ariolas the bigger the better. I will say that I have seen small chested women that are sexy as F:-; .
I love boobs. I've always loved big boobs (D-DDD+). I love it when they're big enough to jiggle when she walks. Nothing like seeing some big fat titties in a low cut top. Makes me wanna stick my face in em and go brrrrrr! They have nipples. They make milk. And if they're big enough, you can even fuck them. Boobs are amazing. That is all.
