I sit as wife's ex kisses her right in front of me

My wife just doesn't get it! She keeps asking why I get so upset! I mean, here I sit as her ex just walks up behind my wife, kisses her neck, pulls her top down and starts caressing her breasts, right in front of me!

He touches her in that special way, and she just purrs as his lips sucks on her neck and his hands cups her fullness as his fingers pinch her nipples erect! She pushes her ass into his crotch as he starts to grind away into her!

She says it's no big deal, he's seen her naked hundreds of times, and he's just being silly! I think it's not proper that she lets him do that to her. After all, she never lets ME do it...
