两个女主人让奴隶记住她们腋窝和脚的气味，并试图猜测这是谁的气味。

Two Japanese girls play a smell guessing game with a masochist. The girls make the masochist smell their feet and pussy to make him remember them. After that, they make him smell their pantyhose and panties to guess whose underwear they are. If he gets it right, he is rewarded with the girls' saliva in his mouth, if he gets it wrong he is whipped. The game continues, and the girls blindfold the masochist and make him smell their feet and armpits to guess whose smell it is. They whip him so hard that he tries desperately to smell them. The girls laugh at him as he tries desperately to smell them, and whip him to relieve stress. For the masochist, it is a game of heaven and hell.
