Bondage and Punishment For All
Two girls are chained to a wall with their tits squished together, kissing through their masks. Their dominatrix arrives to separate them, moving them to the floor masked with their hands bound behind their back. She places a breathing apparatus around one of their mouths, teasing them to share air in order to breath, then closes them inside a rubber bag. Inside the bag they have to kiss and share the oxygen that one girl is getting, they begin to enjoy the intimacy of the bag. When the mistress returns she is disappointed that they enjoyed their punishment.
