What is your preference for body type?

My wife’s body type is exactly what I like. So much that I look for her body type in porn because it turns me on. I can not believe how great my wife’s tit’s are after having and breastfeeding 2 kids. One word, Amazing! Bouncing tits is my biggest sex fetish. Especially when I can watch them bounce when she’s on her back getting fucked by another guy while I jerk off.
Perfect!!
 
It's really hard to tell. My wife is a bit curvy with big round butt and boobies. Hovewer, her friend is very skinny but boy I like her so much. She's got something that turns me on, maybe its her eyes? Personality? I can't tell. I think it's something beyond body shape, something else makes them hot, e.g. thirst for sex.
 
Wile I know this question was geared towards the guys I personally like big guys meaning physically not really fit I like guys who would not have a chance with me on the dating scene which I guess makes me a bitch.
