"We need to talk. I know what you did last night."
I sent this text off to my twin sister; you see, sis has been married for a few years now and her husband is a total pussy. I've witnessed my sister walk all over him in front of family, friends, and even in public; I know for a fact that she doesn't respect him and I know something she thought no one would ever find out.
Last night, I was having dinner at a local restaurant just around the block from my house; it's quite a nice place, especially for a date. It's dimly lit, candles on the tables, very romantic and has a nice selection of wine. I guess my Sis was also a fan of this spot because she was also there last night.. But she wasn't with her husband.
Instead, rather she was there with a friend of her husbands; his name was Marcus. I'd hung out with the guy in a group setting on a few occasions but I personally didn't know much about him. But I do know he's a six foot five, two hundred and forty pound physical specimen; the guy is in tip top shape and he's as black as the night.. Which if stereotypes have taught me anything means he's got a huge black cock.
Sis was clearly blasted on wine as she was all over Marcus before they could even get to his car; his tongue was down her throat and she already had one hand on his semi-erect cock which I could perfectly make out the outline of through his slacks. He slapped her on the ass before grabbing an entire handful of her ass and resting his hand in the crease of her ass crack as he escorted her into the car. I, of course saw that as an opportunity..
With my phone in hand I snapped photos and videos left and right documenting everything I was seeing; I even followed them back to Marcus' place to really get some good stuff on film and boy did I ever. Marcus beat the ever loving shit out of my Sister, choking, slapping, spitting, jamming his cock as far down her throat as she could take it and making her gag all over it. Clearly something that was missing from her marriage as her husband lacked the instinct of being a complete alpha male.
Sis was down on her knees with both hands behind her back and Marcus' 10 inch cock lodged between her teeth; her jaw stretched wide and tears began to stream down her face as he body jerked every time she gagged on his cock. She maintained eye contact and kept his cock in her mouth so long as he pleased. I was shocked with what came next..
Marcus laid my sister down and proceeded to slowly and sensually fill her tight white cunt with his long black rod; he pushed himself all the way inside of her making her take all ten inches of his cock.. But that was that. He didn't fuck her hard or fast, no; this was different. Marcus made love to my sister. Unbelievably so; I certainly have never made a woman moan the way he made moan and I've definitely never had a woman shake and convulse the way my sister did on his cock as he made her cum.
They never switched positions once; Marcus made complete love to my sister in missionary position before filling her up with his black semen. Luckily I was right there in the window filming the entire thing.
That's where this story takes a turn; you've been warned. You're probably thinking this is the part where I'm going to blackmail my sister into having sex with me; you're wrong.
Remember how I said my sister's husband was a pussy? Well, he was more than just a pussy; in fact he was mostly a sissy. Aside from his feminine personality, his body was completely feminine. I'd shared a locker room with him many times and I couldn't keep my eyes off of his smooth body; the way his ass was wider than his hips and bounced with each step he took. His cock although it was always soft, was only a few inches; if I had to guess I'd say he was only putting up 4 or 5 inches rock hard. No wonder Karen was never satisfied with him.
I met with Karen that afternoon to discuss the terms; I sent her one of the pictures I'd taken the night before and hinted at what our little meeting was going to be about.
"I have pictures and videos of you with Marcus last night, Karen." I told her. "This is what I want from you."
I could tell by the look on her face she was thinking exactly what you were all thinking.
"Look if this is some weird black mail you're trying to do to get me to sleep with you.." Karen said, jumping to conclusions.
She and I have always been very close, open, and honest with the other especially about out sex lives; we share a sort of mental bond as most twins do. I'd be lying if I said there wasn't some kind of underlying sexual tension between the two of us and maybe there was.. But that's not what I'm interested in,
"You're sick, Karen. I don't want to fuck you." I told her.
"Then what do you want?" She asked.
"I want to fuck Tom." I answered.
She was silent; at a loss for words.
"Umm.. Excuse me? What?" She was struggling to understand.
I explained to her how I'd noticed his body at the gym and how he's a total bitch; I explained how I've recently started getting into the fetish of tranny's, cross dressers, sissy's, and femboi's. How I wanted nothing more than to fuck a little sissy bitch in the ass and make him completely submit to me and my cock; use him for my own pleasure, as if he was a sex toy built to make me cum.
"How? How do you think I'm going to make that happen? Tom will never do that." She told me.
"I know Tom has always wanted to fuck you in the ass, right?" I asked.
"Yeah, you know I've told you that. I never let him." She replied.
"Exactly." I began, "Exactly. That's how you do it."
"I don't get it." Karen responded.
That's when I broke down my master plan.
"This is what we're gonna do.." I started to explain, "But it's going to take some time."
I explained to her she was going to tease Tom; absolutely drive him insane. Dress like a complete slut in the bedroom, fancy lingerie, rubbing her ass against his cock in bed, etc. Even sucking his cock every now and again but not letting him cum; really get him sex crazed.
"Then one night, I want you to tell him 'I want you to fuck my ass.' Got it?" I asked.
"Got it.. But then what?" Karen asked.
I told her that she was to tease him even further after offering her ass; I wanted Tom to come home to Karen on the bed on her hands and knees like a dog, ass spread wide with a glass plug in her ass. Tom was to come over and remove the plug and put his tongue in her ass; he wasn't allowed to fuck her just yet.. Only with his tongue.
"I really don't see where you're going with this." Karen interrupted.
"Now we're getting to the good part." I told her, "Just when Tom can't handle the teasing anymore, you tell him he can fuck your ass ONLY if you can fuck his ass." I explained.
I went further into detail telling her that she needed to buy a strap-on to fully convince Tom she wanted to fuck him in the ass; next I told her we were going to buy him some nice lingerie and a wig that he would be forced to wear.
