[ARM-916] Men also wear briefs so that the crotch & butt koki contact part of the pants looks good! Part.4

Crotch and butt koki over pants... It's good, isn't it? It is an attractive play that it becomes it as soon as it is actually rubbed... But if you look at the act in AV, I can not see well the part where the essential Chi-po and panty are in contact. I'm in trouble. Then, let's have the boy wear boxer briefs! Then, not to mention the contact surface, it looks good to the texture of the panty that the girl moves the waist and changes every time she swings her ass! It is the fourth series!!
