Slyyy walks into her living room & notices a strange medical mask on her couch with a very long tube leading somewhere. Curious, she sits down & picks it up to examine it. She holds it close to her face & notices that there's a strange gas coming out of it. She inhales a little bit of it, and gives a slight giggle. Surely the gas didn't make her do that... or, did it? She places the mask over her nose & mouth, and immediately begins to laugh. The more she breathes in, the better she feels & the more she laughs. Soon, she laughing uncontrollably & rolling around on the couch, flailing her pantyhose covered legs in the air. Her eyes glaze over & she pulls her huge tits out of her dress & begins to grope herself. A few more hits of the laughing gas, and Slyyy is reduced to a giggling fool.
