My wife invited her sister over for dinner and drinks last weekend. We had a great time talking about all sorts of things and we were feeling no pain. After a few more drinks the conversation started to open up. My S-I-L (who's single at the moment) brought up the subject of monogamy and how she feels it really doesn't make any sense, while smiling and looking me right in the eye. She's very playful and often flirts with me when we're together.

My S-I-L is a good looking girl as is my wife. You can totally see the family resemblance. This is not the first time I've wondered what it would be like to have sex with her but something that night really got me thinking about it, made me horny as hell. I can't help but wonder if she's ever thought about fucking me too.

I can't stop thinking what her BJ would be like, how she tastes, what positions she likes etc. I know I'd never go through with it but...

Anyone else have similar thoughts about their S-I-L? Maybe you've gone further than just thinking about it. And to all the lovely ladies on TERB, ever thought about doing your B-I-L?
take your wife on a hiking trip, and push her off a cliff.

I just so happen to have a great sex life with my wife which on many occasions has included threesomes with some of our female friends. If I have sex with another girl it's with my wife watching/participating.
Is your wife's sister aware of these threesomes? If so, and she's curious about being with you - why not ask your wife if it's okay for a one-time fling? Your wife knows the sex with other females is purely recreational.

of put a pork chop in her pack and leave her for the bears
Why would I do that? I love my wife. :confused:

I would say she's unaware of our sexual escapades. I think it's best left a fantasy.

A few random points maybe will help you get things clear

1. do you have other options of how women, or women that gorgeous
2. has she put the moves on you, or dress seductively , or shown any interest? or shot you down conditionally, in something that you can fix
3. If the family found out, how bad would this be? What would the consequences be?
4. Do you have any other fuck buddies, or alternatives for sexual fulfillment, such as massage parlours/escorts, or friends with benefits?
5.Suppose, she got attached, and you look like you want just the sex, wouldn't that be awkward
6. Would your "wife" be okay with this, if she knew about it? How about if you did it behind her back...
there is the typical "oh sure" a woman could give, but deep down inside I imagine it would hurt, which is why women hate porn, and rather they be your porn collection.

You should be happy that you only have a sister-in-law to deal with.

I have my sister and my sister-in-law to deal with...

Invite her to a hotel, call her up for a few drinks and see how things go, make some shit up and tell her a massage would feel nice right now.

If she grabs your cock Bingo!!!

1. Yes, I have other options of hot women. The first one being my wife.
2. She hasn't put the moves on me, just some innocent flirting.
3. Family isn't going to find out because it's not going to happen. It's just a fantasy as I have stated many times in previous threads.
4. Yes, we have a few female friends who we play with from time to time.
5. Not applicable.
6. See number 3.

My wife loves porn, we watch it together all the time. I came home after work last week and she said she wants to try this: http://www.pornoxo.com/videos/166587/these-sluts-have-ht-threeway-sex.html

You seem like you already know what you're going to do, or not going to do. So go with your gut.

It could be a test, or it couldn't be. Either way, you seem like you love your wife enough that you're not willing to risk it for a fling with her own sister.

For what it's worth, I actually did fuck my SIL once, and my wife was there while it happened. We were all sloppy drunk and it almost happened again many recurring nights but we kept getting interrupted. It was super hot, but the problems didn't come up until later. That was 8yrs ago and I tell ya, sometimes I close my eyes when I'm wanking it and just go back to that night. Oh the things I would have done differently if I hadn't been so drunk and excited as a frat boy!

Anyway, only do it of the wife agrees, is there and you are 100% sure it's not a trap! Then be prepared for the questions of who was better....that shit is not fun!
If the SIL's ever rides him, he should say to his wife, 'honey, it feels good but nowhere as good as you'.

I've already thought of that. lol
Shake your head too while you say it. I bet both of them would laugh.

Seriously though, your S-I-L tempted you by flirting or looking directly into your eyes with this 'I dare you to fuck me' look, right? Well, it's more than just a personal fantasy of yours. You have been tempted sir!

However, you need assurance that it's not a test. Sorry I can't recall the opening post, but you said that your wife brought it up? In what context? Do you think she was serious too? Ask your wife if she has done a threesome with her sister before you were married, etc. (she might not answer that if it happened while you two were dating prior to the marriage, so don't ask WHEN, just if it happened). Did your wife bring it up after your S-I-L talked about monogamy?

Never expect or seek it. If it happens, be surprised and don't show any enthusiasm until they both are down on your cock. Act shy. Your wife will say, 'oh cum now, be the stud that you are'. Then fuck them like a demon!

No, my wife didn't bring up, it's strictly my fantasy. Although my wife likes threesomes, I highly doubt she'd be into one with her sister. In fact my fantasy doesn't involve the two of them, just her sister.

Your wife sees sex as recreational, she doesn't worry about you falling in love. Try bringing up the subject with her, she knows her sister is hot and that you must have thought about this at least once in the past.
The worst that would happen is she says no, she wouldn't go mental on you for thinking about fucking her sister.

This reminds me of an old joke.

I was a very happy person. My wonderful girlfriend and I had been dating for over a year, and so we decided to get married. There was only one little thing bothering me...It was her beautiful younger sister.

One day her "little" sister called and asked me to come over to check the wedding invitations. She was alone when I arrived, and she whispered to me that she had feelings and desires for me that she couldn't overcome. She told me that she wanted me just once before I got married and committed my life to her sister.

Well, I was in total shock, and couldn't say a word . She said, I'm going upstairs to my bedroom, and if you want one last wild fling, just come up and get me." I was stunned and frozen in shock as I watched her go up the stairs. I stood there for a moment, then turned and made a beeline straight to the front door. I opened the door, and headed straight towards my car.

Lo and behold, my entire future family was standing outside all clapping!
With tears in his eyes, my father-in-law hugged me and said, "We are very happy that you have passed our little test. We couldn't ask for better man for our daughter. Welcome to the family!"

And the moral of this story is:

Always keep condoms in your car.

In the spirit on transparency, tell your wife what your SIL was up to when the discussion focused on monogamous relationships and see how she reacts...

Then go see an SP...It’ll turn out a lot better than screwing your SIL...
