My lady friend, Sara, and I had been seeing each other for over a year.
Not often enough, mind you, but as often as we could, as she was still
married. I am a 50+ male and she is a 30 year old female, very pretty,
small but very sensitive breasts, and extremely erotic and sensual. A
dream too good to be true for an old war-horse like me.
We had been talking about inviting a man in for a three-way as it has
been a lifelong obsession of mine to see my lover with another man. Or,
for that matter, another woman. She is fascinated with the idea of going
down on a female. But, that is a story for another time. There are very
few women I have met who would go for it. But, as time went on, Sara got
into the idea. This night we started out in a gentleman's club. We have
done this before, but little did we know how the evening would turn out.
Sara likes it when I buy her lap dances and fantasy room dances. She
tells me the feel of another woman's soft skin is like no other, and it
really is a sight to see her face reflecting the dream state she gets in
when one of the dancers rubs her breasts along the side of her face.
This particular night the featured dancer was a very erotic blond,
Tricia, who was very tall and very well proportioned. She was also a
very good dancer. And, she turned Sara and I both on.

After several lap dances with various dancers, we settled on Tricia.
Shortly, we ended up in the fantasy room. Tricia put on an extraordinary
show and Sara and I both were enjoying things immensely. At one point,
Tricia even asked that I leave the room so she could put on a private
dance for Sara. Of course, Sara was agreeable. So, I went out and had a
drink while they stayed in the room. I get a lot of enjoyment our of
knowing that Sara is enjoying herself. That night was no exception.
After my drink, I went back to the room and we talked with Tricia for
awhile and invited her back to our table for a drink. Try as we might,
we could not talk Tricia into going back to the hotel with us. At
closing time we left, both of us feeling very frustrated.

As we were driving back to the hotel we passed an adult bookstore and
novelty shop. I swung the car around and we went back. Sara had
expressed a desire to get some ben-wa balls and a silicone penis extension.  I thought it was as good
a time as any. After looking at the novelties, Sara picked out a set of
the brass balls and I paid for them. I also purchased a handful of
tokens so we could go back to a booth and watch a flick or two. Settling
into the booth, Sara sat on a stool and I stood behind her. By the way,
I failed to mention that Sara was wearing knee high black leather boots,
a black leather vest, and a black leather skirt. She had on sheer black
stockings, a black garter belt, and black panties underneath. No bra.
She looked fabulous, and earlier many of the dancers had commented on
how much they liked how she looked.

I neglected to hook the door when we entered the booth, and sure enough,
SURPRISE! Someone opened the door, saw us, and immediately shut the door
and went into the booth next door.

Almost immediately, I hatched a plot in my sexually frustrated brain. I
slipped out and knocked on the booth into which the man had gone. The
guy opened the door and I could see he was a man in his thirties, clean
cut, and nice looking. I questioned him about whether he could
"behave" himself if I invited him next door. He answered that
he would only do what he was allowed to do, or prompted to do. I liked
the answer, so I told him to come on.

The first thing I did when we got back to our booth, besides hooking the
door, was to slide Sara's vest down to expose her breasts. We could hear
her suck in a deep breath. Her nipples are always hard, and the coolness
of the booth, and the fact there was a strange man standing next to her,
made them stand out like strawberries on a sundae. I asked his name and
he told me it was Bob. I asked him if he liked Sara's breasts, and he
said, "indeed he did." And, I said they are nice to touch and
that was his cue to go for it. As he massaged her breasts, and lightly
pinched and pulled on her nipples, I could see the bulge grow in his
pants. I said something to S
