ダブルチェック!中出しの義理の妹

We both kneel on the table and behind us there are about 20 men in line to fuck us hot. The men had to decide beforehand which hole they would rather fuck. Those who want to fuck the asshole have to line up on the left, behind my stepsister. Those who want to fuck the pussy have to line up on the right behind me. We just wanted to test which hole is hotter for the cock. Which group cums faster?
