My wife's sister, Lori, works for a bank. She calls on outside clients so she doesn't work in an office, and she does not have fixed hours. I should tell you a little about Lori. She is 13 years younger than I am. She is a fox. Five foot four and a figure to die for. She has long strong dancer legs, a tight ass, slim waist, and really big full soft breasts, green eyes, and long lush reddish blonde hair. But Lori is a screwed up girl. She is in a screwy second marriage to a freak of a guy. Her situation is mostly her own doing because she is a narcissist that uses sex to get what she wants. She doesn't let her husband touch her magnificent boobs just to make him want her more. She will have sex with him only rarely, usually to get something she wants. Her first husband said she didn't participate in the activity at all. "It was like fucking an impatient blow up doll," he said. Lori told my wife that she does not have a climax unless the sex is illicit; she's had lots of affairs.
Recently her bank gave her a computer program to install on her home computer to link it to their system. Since she is not very experienced with computers she asked me to help her.
I went to help Lori one day after lunch. Her husband was at work and her son was at school. We have been alone together thousands of times and other than the fact that I appreciate her magnificent body, there has never been anything even remotely sexual in our relationship. I am, after all, her big sister's husband and because of our age difference I am more like an uncle than a brother-in-law. And I don't put up with her bullshit.
Lori was wearing a very short black skirt and a cream silk blouse. She wore stockings and high heels. She was the picture of sophisticated sexuality and I could understand why she was such a successful "Personal Banker."
As she sat at the computer I was aroused by her feminine allure. Her skirt was high on her thighs. Her blouse was open enough for me to enjoy her full cleavage and the sheer black bra trying to contain her big beautiful breasts.
We spent an hour installing and trying the program and then we began to talk about the Internet and we began to surf. We found her son's "favorite sites". She was appalled to discover all the adult oriented material being spammed to him. She wanted to see it. We looked at a few adult sites and she pretended to be shocked. When we were looking at one site she got all quiet. It was a bondage site and the pictures all showed women tied up. "That's horrible!" She said in an uncomfortable voice.
"Some people find it pretty erotic" I said.
"Sure MEN do. Isn't that what guys like, to abuse women," she said with a bit of a smirk.
"No! I was thinking of it more from the woman's perspective. She can be unfaithful and can have all kinds of sexual things done to her and never feel guilty about it because she had no control of the situation."
"Like that could ever work. A woman is ALWAYS in control and therefore guilty when it comes to sex."
"What do you mean 'ALWAYS in control', does it look like she's in control?" I asked indicating a girl tied to a chair. Her arms and legs were held with rope and a guy was reaching into her dress feeling her boob.
"She's just a model she really doesn't have to let him touch her breast."
I pulled Lori's arm behind her back and said, "Do you really think that tied like this she could control the situation?"
"Sure she could."
"OK Let's just see how much control she could have." I took off my tie and tied Lori's wrists to the back of the desk chair and the pulled her elbows together as much as I could and tied them together. Her chest was forced out straining against her blouse.
"Ron, do you really think she would be out of control? She could just stand up and shake this off."
"Wait a second." I went to the closet and found some scarves. When I came back Lori said, "Come on Ron, you can't win this."
"Watch me!"
I pulled Lori's knees back to her shoulders and tied them. Now her feet were off the floor and she had no way to stand up or grab anything.
"What say you now?" I asked.
"She could still lean over and get all this off and besides she can yell and bite and talk."
Her skirt rode up and I could see Lori's crotch covered with black pantyhose and sheer black panties.
"She has no control," I said.
I pulled Lori's head back and tied a scarf across her forehead and down. This pushed her boobs out even further and she couldn't pull her legs down.
"So much for her biting anyone!"
With her bound like this I could walk around and study her and touch her and do anything I wanted to her. I was getting aroused looking at Lori's spread legs and sexy crotch with only sheer hose and panties covering her puffy cunt lips. Some pubic hair was showing on either side of panties and some stuck through her panties and the stockings. Her blouse was gapping between buttons and her nipples were showing bulges against the shinny material of her blouse.
"Now what was that about control?" I teased her. I spun the chair and touched her feet and ran my hands up her legs to her knees and thighs. I turned her again and rubbed her arms and face. I was standing behind her and I pretended I was going to open the front of her blouse.
"Don't you do it, Ron," she warned.
I ran my fingers down her neck and said, "See, she would have no control! She should just relax and submit herself to it."
When I reached the top button at her neck she said, "Ron you better not!"
But I did.
When the button opened her blouse spread wide giving me a beautiful view down her cleavage. I opened the next few buttons and spread her blouse open. For the first time in my life I had a clear view of my sister-in-law's beautiful tits through the sheer black bra.
"OK Ron, that's enough now. Untie me and let's stop this." Lori gasped.
"I thought you said she was always in control. She obviously couldn't fight her way out of this situation. Do you think she could TALK her way out?
Look at this picture and tell me how much control she had."
I turned Lori so that she could see the picture of another tied woman. Two guys were enjoying her, one feeling her cunt and tits and one had his dick in her mouth.
I couldn't control myself I had to touch her vulnerable body. I lay the palms of my hands on her tits, "How could she avoid this?" I asked feeling her wonderful breasts. Her big nipples were hard against the palms of my hands.
"You are not allowed to touch my breasts!" She almost moaned. I was so excited I thought my heart would burst or my dick would explode.
"Lori, she would have no options in a situation like this." I was still pretending that I was just showing her that control could be taken away from our fictions subject.
I boldly slid my hand into her bra and lifted one boob out of its confining cup. Oh my god; I felt her bare breast. I massaged it and pinched her nipple. This was wonderful. I slid my other hand down and touched her crotch. I could feel the stubble of her pubic hair sticking through the stockings.
"Please Sir, you must not touch between my legs." She meekly begged.
Sir? Was she playing along now? I pressed the raging bulge in my pants against her restrained head as I pinched her bare nipple and diddled her covered crotch.
"OH please stop Sir, I can't let you do these things to me!"
"You have NO choice, Madam!" I barked in my deepest villain voice.
Then I ran my hand down inside her hose and panties and slipped my fingers deep onto the crease between her legs. She began to respond with hunching actions against my hand all the while protesting and moaning that I must not be touching her private parts.
