I find a gas mask at my step-sister's place and wonder what it is for. When I ask her about it she tells me that she is really a secret agent that uses her sexy body to seduce men and extract information from them. The gas mask is part of her secret weapon. Men always want her body, but they don't always want to talk and give up information. To help with that, her secret weapon is a special liquid potion that she uses to put them under her control. The gas mask is her protection from inhaling the fumes of the potion herself. She puts on the gas mask and the men usually think it's kinky. Then she puts a small amount of the potion on a rag and holds the rag against the man's nose and mouth. As he breathes in the potion he will become drowsy, horny and completely under her control. She can find out anything she needs, play with him as she pleases and then put him to rest. Once he wakes up he won't remember anything. She tells me it's a lot of fun being a secret agent and in total control of men. I don't believe her, so my step-sister insists on proving it to me. She puts on her gas mask and starts caressing her body. I find it very intimidating but yet very sexy. I am surprised at how turned on I am getting by my own step-sister. Then she insists that I try it. She pulls out another gas mask and helps me put it on. Then she puts my hand on her body and I grab her large breasts. Then she puts my hand over her mouth and shows me how to gag someone. This is all very new to me and very exciting. While we are doing this my boyfriend walks in on us and looks very confused. My step-sister gets behind him and puts her hand over his mouth. She holds his arms back, keeps a hand gag on his mouth and tells me it's my turn to play. So, I begin to seduce my boyfriend with the gas mask on. My step-sister then hands me a rag dipped in her magic potion and removes her hand gag. I then put the rag to my boyfriend's face and watch his eyes roll back as he breathes in the tired fumes. He is now under our control. My step-sister then takes him starts caressing his body and seducing him with her beautiful large breasts and amazing cleavage. I get jealous and lift up my gas mask. Uh oh, big mistake! When I remove my gas mask I am exposed to the fumes. I get drowsy and horny and fall under the control of my step-sister. I am mesmerized by her large breasts and sexy body. I caress her body and do as she commands. Once my step-sister has had enough fun with me and my boyfriend she puts us to rest. She holds the rag to our faces, our eyes roll and we go nighty night!
