For her it was with my younger brother who has never been married. It happened about two years ago at his house. I gave my consent but was not present since that would have been really weird.

For me it was about six years ago, her younger sister had gone through her second divorce and we were up in Illinois helping her move out of the condo she and her last husband had shared. Her ex husband had already taken his stuff and was gone so it was just me and the two sisters loading stuff up to take to a house she had rented roughly 80 miles away. Over the course of the day her sister was a huge flirt, it must run in the family since my wife is also a huge flirt when she wants to be. As we loaded the truck she kept getting really close to me and telling me how impressed she was with my "muscles."

Once we got to her new house we got the truck unloaded and got the basics set up.It was late evening and I was going to take the truck back for her the next day so we stayed at her new place overnight. We all got a shower and had pizza delivered and tried to sit down for the evening in the midst of the boxes and clutter. The cable or internet was not connected yet so it was a quiet night. My sister in-law was on one side of me with my wife on the other and my SIL began to rub my shoulders and told my wife if it was ok with her that she would give me a massage. She worked in a salon that did hair, nails, facials and massages and she was a licensed therapist. Without ever saying a word to me my wife agrees and they are off to locate and find her massage table which they set up in the living room and find sheets and her oils. My wife tells me to get undressed and I strip to my boxers and walk over to the table and and as the girls are talking together my wife says "you want his boxers off too, right?" and my SIL says "absolutely." My wife pulls my boxers down and I lay on my stomach on the table as my SIL begins to rub some oil into my shoulders saying "I usually begin with the front side but this works too." She rubs me very deep as she and my wife stand and continue their conversation before she moves down and compliments my ass to my wife. She is really working my ass and my balls are also getting some action as I get hard. My wife and her sister continue talking about my body and the conversation moves to happy endings. My SIL tells my wife she needs a happy ending and confesses that she and her ex had stopped having sex when the problems began over a year ago. My wife responds just as matter of factly as if offering to let her use our car "You should fuck, XXX, I know you would enjoy him."

I cannot believe my wife just offered me up for sex to her sister. Her sister replies asking if my wife is sure she wouldn't care and then begins to get undressed. Now, for the first time I am sitting up looking at my sister-in-law naked. Her body was similar to my wife's but her hips were wider and she had a bigger ass. She also still had a bush like my wife used to have.

We end up on the unmade mattress in the bedroom as my wife is in the room telling me I should eat her sisters pussy and that she will probably like that since she does so much. Her sister turns out to be a total freak once we get started and goes wild. Once we were both done we get up and my wife tells me, "Where are you going? You need to do me after me watching that." My wife stands at the bed and undresses now as her sister stands still naked and says she wants to watch this. It took my wife about 20 minutes to get me hard again but the sex was amazing once we got started with our audience observing closely. Afterward both my wife and sister-in-law are on the bed talking about, men, oral sex, and how much my wife enjoys anal. I am watching them and they both have my cum leaking from their pussy. My SIL says she has never tried anal before and they talk before my wife tells me that before we leave tomorrow I had to give her anal.

I tried to talk them into doing a FMF that morning but I got called a pervert. I did get to fuck her sister in the ass the next morning and that was really hot. She had a hard time taking me inside her but I spent a lot of time and finally she was wanting more and harder. She was like my wife and also was able to orgasm from straight anal.

It has never happened again or come close. We see her a few times a year and she dates on and off but I guess it was a one time thing. I still sometimes can't believe it happened. It was not ever anything I worked for or thought of.

You are my hero!
