My jaw hung open in shock as I watched the video. Bluntly, it felt like someone kicked me in the balls. On the TV was a tape of my wife and brother-in-law. They were fucking. I couldn't believe it! Not only was my wife Sally cheating on me, but also she was doing it with her sister's husband Bob to boot!
My sister-in-law Jane was standing next to me watching my reaction to the tape. She was obviously hurt and angry. She found it hidden in her husband's den only a couple of hours before. As the tape continued, I walked to the bar in the corner of the room and poured two drinks. Jane took one without a word. We watched in silence.
It was obvious Bob worked out a lot, but I was happy to see that all those muscles didn't make his cock any bigger. At least I was better built in that department. Of course, Sally seemed to be enjoying what Bob was doing to her regardless of the size of his equipment.
My wife was athletically built. She went to the gym daily and was always on my case to go to with her, but I never was into that kind of stuff. As I watched, I wondered if it would have made a difference.
Jane went and got herself another drink. I watched her as she went. Jane was ten years younger than Sally and had far more curves than her sister. Her tits were bigger too. I'd watched her mature into a beautiful young woman over the last few years.
She and Bob married two years ago. Sally and I were married far longer and we had three children. Our twentieth anniversary was coming up soon.
"Do you know how long this has been going on?" I asked once the video ended. Sally shook her head.
"It could be years!" she snapped. I shook my head.
"No, this is something recent. Sally has been acting weird for the last month or so and now I know why," I replied.
"My own sister!" Jane said venomously. I shrugged. There was really nothing I could say that was going to make that fact any better.
"What are we going to do?" she asked, visibly shaking with anger.
"I don't know," I sighed. I was still too shocked to think clearly.
"You don't know?" she asked incredulously. I shrugged again.
"Your sister and the kids are down at the shore house this week. They won't be back for a couple of days. Your parents are staying with them. I guess I'm going to give it twenty-four hours before I make any drastic decisions."
"Well, I know what I'm going to do!" Jane snapped. I placed my hand on her shoulder, trying to calm her down.
"Isn't Bob out of town on business this week?"
"Yes," she replied, but added angrily before I could continue, "He's probably fucking someone else right now!"
"I don't think so," I said with a shake of my head.
"What?"
"Look, I know Bob pretty well and he's not the type to fuck around," I said, knowing how silly my words sounded.
"You've got to be kidding," Jane snorted. I shrugged.
"I don't know what happened, but I can't believe Sally and Bob intended what happened."
"It certainly looked intentional on that tape!" Jane cried.
"Has anything been wrong with Bob lately? I know Sally is feeling her age. She just turned thirty-nine and the thought of turning forty next year is really bothering her."
"That's some excuse!"
"I'm not saying it an excuse, but I do think it's part of the reason," I said. Jane looked at me and shook her head, but then she sighed and seemed to calm down a bit.
"We've been trying to have a baby for over a year now with no luck. I know it's bothering Bob," she replied rubbing her temples, but then the momentary calm disappeared and her eyes flashed angrily as she added, "It's bothering me too, but I didn't run off and fuck one of his brothers!"
"You're right," I said, trying to placate her. "But I still think that we should take a day to think before we do anything drastic."
"Fine! You're probably right, but I don't think it will help," she snapped. Her pain and anger were almost too much to bear.
"Why don't you come back tomorrow night and we'll talk," I offered. "By then we'll both have had time to calm down."
Jane didn't look happy, but she nodded in agreement. She pulled the tape out of the VCR and left without another word. I hoped she wouldn't do anything stupid until she calmed down.
I decided to take a shower. I felt somehow dirty. I went into the bathroom, turned on the hot water and looked at myself in the mirror. The room started to fill with steam as I continued to stare into my own eyes. It was going to be a long night and I doubted I would be going to work in the morning.

Jane was at my house early the next evening. She looked like she hadn't slept any better than I, but at least she seemed a little calmer.
"So, what did you decide?" she asked without preamble. I shrugged.
"Doesn't it bother you?" she asked incredulously.
"Sure it bothers me, but there's not a lot I can do about the past." The truth was that I was more bothered by the feeling of betrayal then by the actual action.
"Do about it? I'm going to leave Bob! You should leave Sally too!" Jane snapped. I shook my head, realizing I had actually made a decision.
"That's not going to happen. Your sister Sally and I have three children. We've spent all of our adult lives together," I sighed, and then added, "I love your sister very much and her fucking Bob isn't going to make that love go away. I'm hurt and I would like to know why she felt the need to cheat on me, but I'm not leaving her." Jane stared at me.
"You're going to forgive her," she said in amazement. I nodded. Jane shook her head as the tears started falling. I pulled her to me in a hug and she sobbed. This went on for quite a while before she could gain control of herself.
"I don't think I can forgive Bob," she finally said.
"Jane, do you really want to leave Bob?" I asked. She hesitated before shaking her head.
"But I can't just let him get away with it," she said forlornly.
"Let's have a drink," I offered. She nodded in agreement.
The first drink was more of a shot than an actual drink. The next one took longer. I excused myself to the bathroom while Jane poured the third round. I came out of the bathroom to find her watching the tape again. I sighed, walked over and turned it off.
"You know, that's not helping," I said. She shrugged. We drank the third round in silence. This time Jane excused herself to the bathroom while I poured the next round. I wasn't drunk yet, but the pain was beginning to recede a little.
Jane came out of the bathroom and walked over to me. I noticed almost immediately that something was different. First, Jane looked liked she'd made a decision. Second, it was impossible not to notice that the first few buttons of her shirt was undone and that she was no longer wearing a bra. I could see her nipples clearly through her blouse.
"Jane, what are you doing?" I asked in confusion.
"I'm going to do the one thing that might make my marriage survive Bob's cheating. I going to fuck you silly," she replied. I thought to argue, but she was already kissing me. Besides, the truth be known, even though I decided to forgive Sally, I was hurting just as bad as Jane. Fucking Jane, wrong or right, would probably help. I doubted it could hurt.
We were out of our clothes in a flash and I was surprised to see that Jane's chest was even bigger than I imagined. My wife Sally's breasts barely filled a B cup. Of course, I always thought that her nice long nipples more than made up for the size.
Yet Jane's rather large chest was a sight to see. She was probably a C cup, but it would definitely be a full C cup. Her nipples weren't as long as her sisters, but they were bigger around. She caught me looking and smiled.
"There all yours," Jane said as she lifted her breasts and squeezed them together. I finished my drink as a shot once again and buried my face between them. Jane reached down and grabbed hold of my dick.
"My, you have a big one!" she said, her desire thick in her voice. I worked my way down to her body, past her stomach and began lashing her pussy lips with my tongue.
She leaned against the nearby wall and held my head with her hands as she moaned. Jane began trembling as soon as I concentrated on her clit. She came suddenly and I had to catch her before she fell. I carried her upstairs to my bedroom.
Jane climbed in, lay down and held her arms out to me. I crawled on top of her and kissed her deeply. The head of my dick found the entrance to her pussy and she gasped.
"Are you sure you want to do this?" I asked. She shrugged.
"My sister, your wife, fucked my husband. I think it's only fair that I get to fuck you in her bed. This way I get even with both Bob and Sally at the same time," she replied angrily, but then she smiled and added, "Besides, I can't pass this up after seeing the size of your cock." She then gasped as she used her legs to pull me into her.
"I feel so full!"
I only had three quarters of my dick in her. I pushed again, but she cried out in pain. I tried to stop, but she wouldn't let me. She was gasping in pain and pleasure as she continued to use her legs. Her hands grabbed my ass and pulled hard to help get the last couple of inches in.
"Oh my God!" she screamed once I was fully in her. I held still until she got used to the size.
"Do it! Fuck me!" she finally said and that's exactly what I did. I pushed in and out of her slowly at first, but at her urging I was soon slamming into her. She started cumming and didn't stop. I thought she was going to pass out as she screamed out in ecstasy.
"Jane, I'm going to cum!" I cried. She rolled us over and began bouncing on my dick.
"Do it! Fill me with your cum!" she yelled.
"But, you're not on the pill!" I cried back. If anything, that made her bounce harder and I came deep inside her. I filled her pussy with so much of my cum that it dripped down her legs.
We lay still for quite a while with her still on top of me. Finally, she lifted her head and looked at me silently.
