Is time sharing my wife.

We had such fun, wife and I, telling each other about our adventures and finding out we didn't shock each other, that we were accepting of each others desires.  Wonderful to experience non-judgement in and area of life there is so much societal judgement.  I  My wife preferred older guys.  I was 10 years older than her.  But our favorite lover turned out to be 10 years younger than her.  He was in graduate school, medical school actually, and an amateur masseuse.  He turned out to be our breakthrough guy.  He and I were talking online and, with her ok, I first invited him over for drinks.  He showed up and was very good-looking and well spoken.  We enjoyed conversation and drinks and he left.  After he was gone my wife said she felt good about him but was I comfortable with him being so attractive, would I be jealous.  I assured her I was fine and we called later and arranged to meet him a week later and would he bring his massage table to massage my wife, M.  We meet him at a hotel room and it started out as a normal massage, but as she warmed and got more comfortable his hands began to explore a bit and she began to move her hips against his hands and fingers.  Little moans came from her and I leaned down and kissed her back and shoulder.  He was clothed at that point, but I began to take my clothes off and soon he was the only one with clothes on.  Didn't seem right.  My wife saw I was hard and smiled and I whispered to her asking if he should take his clothes off.  She said yes and soon we were all naked.  She was so enjoying his massage, so relaxed.  As his fingers found her pussy I saw his cock was rock hard and a bit longer than me, perhaps 8 inches.  I was so turned on by what was happening I started to help him caress my wife and soon, as he continued to caress and work her muscles I got behind him and began to stroke his cock.  He moved his hips against me as I stroked him and before long my wife was off the table, both she and I on our knees sucking his gorgeous cock and kissing each other as our mouth explored and enjoyed him.  It was so freeing to share him in that way with the person I loved most and she was not only supportive but genuinely turned on by it.  That was all that happened that night as we were feeling things out.  But the next weekend, after we had talked about it all week, how wonderful it was, she and I were in bed, middle of the day, masturbating side by side as we talked about him.  It was so erotic at one point she turned to me and suggested we call him right then and see if he was free.  She looked me in the eye and said she needed to have him inside of her and was that what I wanted.  I told her I wanted that more than anything.  He was soon on the phone and we told him the door would be open and to come in and find us in the bedroom.  We heard him come in the house 20 minuted later and he was soon by the bed watching us pleasure ourselves as he removed his clothes,  When he got on the bed he was soon between her legs, I was holding her and kissing her as she moaned and between our kisses told him how good his lips and tongue felt and how much she wanted to fuck him.  Oh, is there anything more erotic than holding the woman you love while she, for the first time, cums on the tongue and mouth of another man.  And then to lay beside her as he rises and you take his cock in your hand and rub it up and down the lips of your wife's pussy followed by the wonder of it sinking deep inside of her as he takes her completely while you stroke and whisper to the two of them.  It was the most erotic experience of my life, to share her, the two of us enjoying her and each other back and forth.  The most natural thing in the world really. I had shared the wife of quite a few couples over the years before meeting my wife, always curious about what the husband was feeling and the often intensity of his reactions. I now understood.
