My story started on a Tuesday night. My roommate Mike was off to work. He worked overnights. Mike's girlfriend, Melanie also lived with us. She was planning on going out with some friends to a local bar. It was perfect for me because I would have the whole apartment to myself. I had took the week off so I could get some of my own kind of relaxation.

After they had left I started on my fun for the night. Since I do triathalons I have a smooth hairless body and am pretty slim. I started out by getting dressed. First I start out by putting on my black silk panties and matching bra. Next come the black silk stockings complete with garter belt. Then I slither into my own little black dress and finish it off with the black heels with ankle strap. I do my face up with makeup and complete the ensemble with a black wig. To top it off I put on my black elbow length opera gloves. With my slender athletic build I could pass if I ever wanted to go out. I never do though. I am completely heterosexual.

Next comes my bondage. I lock up my penis in one of chastities where you put it through the metal tube and the handcuff arm locks around the base so you can't get it off. I lock my ankles with a pair of leg irons. Basically like handcuffs but with a longer chain so you can walk. This chain is only 6 inches long. Then I shove an inflatable penis gag in my mouth and strap deep into my throat. I pump it up until I can't mumble a sound. I then complete my bondage with a pair of handcuffs. I lock one wrist then run the other around the chain locking my ankles and around my other wrist and lock it shut. I am now in a hogtie. I have the keys to the ankle cuffs, handcuffs, and penis chastity all on one keyring. It is close enough to get to but far enough away so I can struggle.

I love to struggle for a while. Feeling the garters pull on my stockings gives me a rush. Being tied up and dressed as a slutty whore turns me on like nothing else. About an hour into my personal fun I though I heard the apartment door open. I listened real quietly. Then I heard the door shut and a pair of keys drop on one of the end tables. I could hear Melanie talking to herself. What was she doing home so soon? My bedroom door was shut and I was hoping Melanie would just go to her room. I thought to myself I have to get the keys and get loose just in case she knocked on my door. Then it happened.

"Knock, knock, coming in." Melanie said as she opened my bedroom door. "OH my God! What happened to you?"

Melanie was also dressed just as sexy as I was. She also had a dress on with stockings and heels. She knelt down beside me and pulled the penis gag out of my mouth. I tried to think of something to say.

"Someone broke in and they had a gun and they made me dress up like this and then they tied me up." I said as it was the only thing I could think of.

"Yeah but nothing is missing or out of place. And why did they leave the keys so close to you? Another thing, why are there three keys instead of two?" Melanie replied.

Lifting the front of my dress up she sees the penis chastity locked on me. I start pleading with her to release me but she just sits there pondering what the hell is going on. Then I see her smile like a light just went on in her head.

"You did all this to yourself thinking no one would be home for hours. You like being a bondage whore slut. I think I have an idea" Melanie says as she picks up the phone.

"Hi honey. You'll never guess what I just walkied in on?" Melanie says as she turns around and walks out of my bedroom still talking to her boyfriend.

I try to release myself but then I realize she has the keys. I hear her put down the phone after about ten minutes of talking. She comes back into my room with a big smile on her face.

"Alright Melanie you had your fun. Come now and let me go."

"Let you go? I don't think so. We have some fun planned for you later when Mike gets home. You want to be a woman? Then there is one more thing you must do."

"What is that Melanie?"

"You are going to suck Mike's cock and swallow all of his cum and I am going to fuck your pussy."

"No way is that going to happen." I scream

"Like you have a say bitch. You ever want that cock released ever again you'll do what I say." Melanie yells back.

"Actually I am going to take a bath and I need to get you a little more comfortable before I do." Melanie tells me.

Melanie then grabs my hair and yanks it until I open my mouth to scream. When I do she shoves the penis gag back into my mouth and inflates it until I think my mouth is about to explode. She tells me to get used to that because the real thing is coming soon. Melanie disappears for a few minutes and when she comes back she is carrying a dog collar and a bunch of rope.

"I need to release your handcuffs and ankle cuffs to get you more somewhat prepared. I have taken pictures of you in your predicament. So if you try anything your family and friends get the copies. Do you understand me?" Melanie said.

I shake my head yes as she starts to release me. She leads me to their bedroom and proceeds to put the collar on me. She takes some rope and ties my hands behind my back. Melanie takes another piece of rope and loops it around my tied wrists and pulls them up behind my back and ties it off around the collar. Now my hands are pulled way up so they leave my ass completely exposed. Melanie then places me on her bed face down. She ties one ankle to one bedpost and the other ankle to the opposite bedpost. Now my legs are spread apart leaving me really vulnerable.

"Don't go anywhere. I'm going to take a bath. Just relax and enjoy tonight. No one is going to hurt you. Well I might hurt you depending on how much lube I decide to use. HA HA HA HA." Melanie laughs as she disappears out of the room.

I lay there for the next hour or so. I can't get free nor do I try considering the pictures she has threatened to send out. After a while I hear Mike come home. He must have left work early considering the clock on their bedroom wall read just after 3 AM. He doesn't even come into the bedroom. I can hear him in the shower. Half an hour later they both come into the bedroom. He is naked and blown away by the sight of me dressed as a woman and tied down to their bed. Melanie is in all black lingerie but what I notice is the 10 inch strapon dildo attatched to her waist.

"Dude I can't believe Melanie talked you into this." Mike says

In my head I'm thinking WHAT?. I would have denied this if not for the cock gag in my mouth. As Mike climbs onto the bed Melanie whispers into my ear.

"When I take your gag out you say nothing and take his cock down your throat. You suck his dick until he blows his load down your throat. Meanwhile I am going to rape your back door. I told him you agreed to all this even the penis chastity. Deny it and that thing never comes off." Melaine whispers to me as I agree to it all.

What else could I do? I was her slutty whore. Melanie removed the gag out of my mouth and I did as I was instructed. Mike sat in front of me and I swallowed his entire cock into my mouth. I was hoping he would be quick and blow his load. Melanie informed me it usually takes half an hour. As his cock pounded my mouth I felt Melanie insert the dildo into my ass. They both pounded away at both my openings. Like she said, half an hour later of sucking Mike's dick I felt him tense up and shoot a giant load down my throat. I cleaned his entire shaft with my tongue. He got up and left telling me thanks on the way out.

He kissed Melanie on the way out of the bedroom as she continued to rape my ass. After he was gone she explained to me that this is what is going to happen every Saturday night from now on. I had no choice to agree to whatever she wanted. After another half hour of pounding my ass she released the chastity. Melanie untied my legs and had me stand up. She pulled out of my ass and took the condom off the dildo. I was informed to shoot my load on the dildo while she masterbated me. It took me no time to cover the dildo with my cum. Then Melanie shoved the dildo im my mouth making me clean my own mess off of it.

Later on she took me back to my room still tied up and still dressed en femme. She put my chastity back on and told me as long as I did what she told me she would release me once a day to relieve myself.

That was a month ago. Every Saturday night I am tied up dressed like a woman and used by both of them. I have never told Mike that I wanted to stop. I am too afraid of the evidence Melanie has on me.
