New story



My wife’s older sister is an aggressive slut. She seems always have a different boy friend and is so pushy and sexual. I have to admit she is gorgeous. My wife is quite different than her. She is very attractive but does not have the confidence that her sister has. Her sister knows this and is always trying to push my wife to be more aggressive, especially with me.

The sister in-law came to visit and as usually showed up wearing a short skirt and low cut top. I know she does this to make me feel uncomfortable. When I was first dating my wife, I was attracted to her sister but realized quickly that I was no match for her and she knew it.

She will sit across from me and leave her legs parted just enough so I can see her panties but not enough to make it obvious. My eyes will always seek out the white triangle and as I look up she will be looking right at me, knowing that I was sneaking a peek.

Many an afternoon I will masturbate with images of my sister in-laws panties in my head. I fantasized about her often. I know that she views me as not manly enough for her sister and tries to get my wife to cheat on me. Unfortunately I have a cuckold nature and if my wife had any interest in cheating, it would be easy for her to do. I also believe that my sister in-law is aware that I am a cuckold wannabe.

One evening the three of us were sitting having wine and talking. Of course I was across from my sister in-law and she was on the couch. As usual she was giving me numerous shots of her lace panties. Her skirt had ridden up her legs and she had them slightly parted. Her panties were white lace and see thru above the crotch piece. I could see the dark of her pussy hair thru the lace.

“I am surprised you are not playing with yourself”, she suddenly said. “What?”, I answered. My wife looked at me and smiled. “You’ve been staring at my panties for half an hour”. I turned red and feebly tried denying it. My wife laughed and said that I played with myself all the time. My wife knows that I am a chronic masturbator. We pretty much don’t have sex and I think its because of that. I always wondered if she said anything to her sisters.

I was just caught peeking and outed to her sister about being a masturbator. The effect was strong and made me feel like a little boy sitting with women. I swallowed and looked down. They both were silent for a moment looking at me. Then my wife and her sister started giggling.

“I’ve told her you are a wanker”, my wife said. “You might as well play with yourself”. I looked at my wife with sheepish eyes and asked “Really?”. “Go for it”. I started unbuckling my pants and my wife commented that I should run and get my Vaseline.

When I returned they both had the heels on the couch with their legs parted, giving my a view of both of their panties. I went to town on my penis. My sister in-law just gasped and said “Oh my God!” My mind was consumed visually with their panties and the thoughts of the future. I just completely humiliated myself in front of my wife and her sister. Would I ever have any chance of dignity?

“We are going out tonight”, my wife said. I just kept stroking and staring between their legs. “I think your wife needs to have a little fun of her own tonight. We are going dancing while you stay home and play away with yourself.”. I came all over myself.

They stood up, my sister in-law shaking her head at me. My wife leaned over to kiss me. I puckered my lips but she just giggled and kissed my forehead. “I don’t think so”, she said. “I think you should be in the bedroom when we get home. We may have some company”.

“Yes dear”.
