A few years ago, a couple we knew from a couple's bowling league
invited us and two other couples to go swimming in their pool one
evening. When we got there, they announced that their pool was
clothing optional, so we could skinny dip if we wanted to. 

Our host and hostess both undressed by the diving board and when
they were bare-ass naked, they each went off the diving board
into the nice warm water. One of the other couples were European
and they quickly stripped and dove in also. When our next door
neighbors and us hesitated, they began urging us as they splashed
in the water. 

The neighbors began to slowly undress, so it looked like they
would swim naked also. I got excited and slipped off my shorts,
shirt, and underwear. I saw the English gal eyeing me as she was
treading water a few feet away from us. My wife had not made a
move...she was just standing beside the pool watching everybody
get naked! 

I don't think she realized that I was standing behind her nude at
the time. It didn't look like she was going to join in without
some encouragement from me, so I began to pull up her shirt. She
lifted her arms as I pulled on her shirt and allowed me to pull
it over her head. Next, I unzipped her shorts and pulled them
down her legs. She cooperated and stepped out of them. She hadn't
said a word so far, so I unsnapped her white bra and drew it down
her arms. Now, all could see her perky tits. Even though it was
nighttime, the pool light was enough to illuminate the scene. 

Stripping her in front of our neighbors and friends was an
instant turn-on and I felt my cock begin to rise. I knew the gals
could see my erection as I moved around. Finally, I put my
fingers in both sides of my wife's panties and hesitated just a
few seconds. She continued to stand transfixed in the glow of the
pool lights with her lovely tits exposed. I slowly pulled her
panties down her legs and her sparse, light brown bush began to
appear. In a matter of seconds, all could clearly see her pussy
lips, because her hair isn't dense enough to cover much and you
can see her slit through it. Again, when I reached her ankles,
she lifted each leg so that I could remove her panties

. My effort, slowly stripping her as everyone watched, was highly
arousing to say the least. The guy next door had not yet entered
the water and his stiff cock was bobbing as he watched me reveal
the wife to the group. Once she was naked, I turned her to me and
gave her a long, deep kiss. She returned it passionately, so I
knew that she was aroused like never before. I touched her pussy
and it was soaking wet with her juices. 

Our hostess had been watching nearby, and she splashed us with
water and laughed. She said, "You two better get in the pool
before you burn up!" She splashed us again and two others joined
in on the fun. Finally, my wife laughed and did a cannonball into
the pool. I went to the diving board and stood there for a minute
surveying the scene below. I noticed the gals checking out my
stiff cock as I stood on the board, then I jumped in and joined
the fun. 

We didn't swap mates, or anything of that sort, but I will always
remember how arousing it was to undress my wife while twelve eyes
watched us.
