I couldn't help but to go home and fuck my wife while thinking about her. From then on I found myself getting more and more looks at her. I would peek through windows when she would visit us trying to see her naked. I was never ale to see her pussy but my fantasies grew about having her sex. It didn't help having her husband tell me all the nasty things she would do for him.
One-night things seemed to come my way. My wife and Brenda worked for the same company in different divisions. There was a company party and Brenda's husband, boys and my son were out of town on a soccer trip, so she decided to ride with us. It was the middle of the summer and when we picked Brenda up she came out wearing a short cotton sundress. I thought I was in heaven when I caught a glimpse of her panties when she got in the car. Little did I know how much better it would get.
It was a warm evening at the party and every one was having fun and the drinks really started to flow. My wife was getting pretty loose as well as Brenda. I noticed that Brenda was talking with one of here bosses and seemed to be acting a little reluctant. I saw her shaking her head saying "no" but then she seemed to give in. I saw her walk down the hall and go into a room with an older guy named Don, and they closed the door. Of course my curiosity was up. So I slipped outside into the dark and went to the window to see what was going on.
I looked through I could see Don trying to kiss her and grabbing at her ass through her dress. She was resisting and pushing him away. I finally heard him say "You know what the deal is Bitch if you don't want me to tell." At that point he put his mouth to hers and she relented. I saw his hands move to her bottom and raise her dress exposing her small bikini panties. I couldn't believe my eyes and knew I had an opportunity.
I saw that he had Brenda bent over the arm of a couch and had pulled her panties down. Her sex was exposed to me and Don was roughly kneading her ass and pussy. She was grimacing as he roughly manipulated her and pulled at her lips. I guess due to summer swim season she had shaved her pussy. She had huge lips and the way her legs were spread you could see all of her sex and her puckered little anus. He suddenly raised his hand and slapped it down on her ass; she squirmed and pleaded for him to stop. You could tell Don liked being rough with her and had something on her. He slapped her ass several more times with stinging blows and said " are you going to mind me now?" All Brenda could do was whimper and plead She finally said " Yes, but please don't tell and don't hurt me".
By now I was extremely excited about seeing my sister in law's naked shaven pussy in front of me and being disciplined by another man. Don made Brenda get to her feet and face him, he looked at her and said " you know what I want now take care of it." Brenda looked at hem and said " No please Don, don't make me do that again." Don put pressure on Brenda's shoulders and she sank to her knees. Don reached down and unzipped his pants. He pulled out his very large dick and you could see the reluctance in Brenda's eye's. Slowly, Brenda reached up and held the dick in her hands. She leaned forward and started to suck him. I thought I was going to fall over seeing my own sister in law sucking some strange mans cock. He put his hand on the back of her head and started making her fuck him with her mouth. With each stroke it went deeper into her mouth and throat. Several times she gagged and pulled away, but Don wouldn't relent and kept shoving his dick down her throat.
Suddenly, I could see that Don couldn't take much more and was ready to cum. He held her head with two hands now and pumped at her mouth. He moaned and stared pumping thick squirts of his semen in Brenda's mouth. All she could do was swallow and hope she didn't get any on her. When he was finished he picked Brenda up, kissed her and said he would talk to her at their next meeting at work. Apparently this had gone on for some time. Don disappeared from the room leaving Brenda to straighten herself up.
I returned to the party almost everybody was drunk especially my wife. Brenda was acting as though nothing had happened but she was pounding a lot of wine. The party became more rowdy and drinking games were going on. By the time it was time to leave I had to pour my wife and Brenda into the car. My wife wanted to lay down in the back seat because she wasn't feeling well. I put Brenda in the front seat. As I was putting Brenda in the car my hand brushed against her ass and I could feel her small panties. When she was in the car her dress had ridden up a little allowing me a beautiful look at her thighs. All I could think of was what I had seen earlier.
On the way home both girls went to sleep, when we got close to home my wife said that she was going to be sick. We went to our house so that I could get her in bed then I would take Brenda home. After putting my wife to bed, I returned to the car to find Brenda in a deep sleep. I tried to wake her but got no response. I reached up and touched her face and pretty hair. I touched her soft lips that had earlier been sucking a large dick. She didn't move and I headed to her house.
When we pulled into the driveway I found her keys and went and unlocked the door. I got in the car and sat beside her trying to wake her up. She was out. I looked at her and realized that her legs were apart. Cautiously I reached out and rubbed the side of her breasts through the dress, remembering her long puffy nipples. When she did not move I laid my hand on her leg and gently rubbed it. Now I was feeling very bold and undid a couple of the front buttons on her dress and opened it up exposing her small breasts and low cut bra. I gently cupped her tits and started massaging them. When she didn't move I quietly pulled the bra over her tits and exposed her nipples. I just sat there and stared at them feeling my hardness beginning to grow. I thought at first that if I got caught I was dead meat.
I leaned forward and lowered my mouth to her nipple and began to suck. I slid my hand under her dress and began to rub her pantied pussy. I could tell that she was wet and soon I slipped my hand under the crotch of her panties. I rubbed her fat lips and pulled them apart. After teasing her lips I stroked my finger across her wetness and over her clit. It felt so good and I had always wanted to touch her. I slowly entered my finger into my sister in laws pussy. I was excited and started to fuck it in and out of her, I pushed her legs further apart and pushed two fingers in to the hilt while sucking her nipples roughly. She started to move her hips a little and get wetter.
The next thing I knew Brenda was awake and said, " What the hell are you doing!" She was squirming to get away. I was scared at first, but then I looked at her and shoved my fingers deep into her. " I'm doing something I've wanted to do for a long time, I'm fucking your pussy with my fingers."
Brenda. "Oh my God, STOP!!. You're not supposed to do that."
With that I just told her, " Listen Brenda, you weren't supposed to be sucking Don's dick tonight either, do you want anyone to hear about that?" "I've wanted you for along time and you're going to cooperate whether you like it or not. I'm going to take you inside and taste that sweet little pussy of yours. Or would you like me to tell on you?" I got out of the car and walked around to her side. I opened the door and told her to get out and we walked inside. She looked at me and asked me "How could you do this?" by now I was too excited. I told her the different times I had looked down her blouse and seen her nipples and how I had masturbated with her panties in the bathroom and now I was going to have what I wanted.
