My wife Dee and I were spending time at a small RV resort. It was not the height of the season, so the park was not very busy. There was a very nice, cozy (i.e. rather small) hot tub, which we soon discovered was not used at all, it seemed, late in the evening. It was tucked in the corner of the swimming pool area, with the gate on the opposite side of the pool. We started going there later and later and never saw anybody after 9pm. So we began going about ten o'clock and slipping our suits off once we were in the hot tub. After a couple nights we went there with just our robes on, but carrying our suits just in case.
Let me tell you about my wife again. Dee is five-six with a chest that makes men drool. Not huge, just large (natural) and well-shaped, with sensitive nipples that seem to be rock hard all the time. Long toned legs and a tight ass from lots of walking, her second favorite exercise. She wears her hair short and somewhat spiky, and it is a rich red color. Me, I'm just an ordinary guy. We are in our 40's, but are told we don't look it.
One night we had been out late at the movies and didn't get to the hot tub until just about 11pm. We were in the water only a few minutes when we heard the gate close and saw a man heading around the pool towards us. Not much we could do as our robes, and suits, were on a chair twenty feet away. He didn't notice us until he was almost to the hot tub.
"Sorry," he said, "Didn't expect anyone to be here. I usually have this all to myself at this hour."
He looked about our age, tall with his brown hair cut short. He was in a robe and carrying a towel.
I told him that we were usually there an hour earlier, but were running late that evening. He noticed that we were not wearing suits and smiled.
"I use these late hours for skinny-dipping myself." He said.
"We don't mind sharing if you don't." I told him.
He shrugged, took off his robe, tossed it on the chair next to our robes and climbed into the hot tub. He had an average build and a slightly above average, uncircumcised, cock. I saw Dee taking particular notice of that.
Once in the water we all introduced ourselves, his name being Danny. He was married, but his wife never came to the pool or hot tub. He indicated that she was a very large woman and felt uncomfortable about that, so she rarely socialized with folks at all.
Dee was sitting on my right and he was sitting directly across from us. As we sat and chatted Danny did little to hide the fact that he was checking out Dee. There was an underwater light in the tub and the water was crystal clear, so he had a good view of her entire body. We, in turn, had no difficulty seeing his growing arousal, which he made no attempt to hide.
I began running my right hand up and down Dee's thigh and she parted her legs slightly, giving Danny a great look at her pussy. Her nipples were hard, giving away the fact that this was starting to get her worked up.
The talking had stopped as Danny looked at Dee, she looked at his now erect cock, and I watched them both looking at each other. I reached across and began playing with her nipple with my left hand as my right made its way up between her legs. I leaned in and started kissing her neck and ear, and her hand found my growing dick. She moved her fist up and down my shaft while still looking at Danny's, as he slowly stroked himself.
Dee moaned as my fingers ran up and down her slit and applied slight pressure on her clit. A slight gasp escaped her as I slid two fingers into her hot pussy.
I looked at Danny and when he glanced at me I gave a little head nod, indicating he should join us on our side of the tub. He raised an eyebrow, smiled and moved to sit on the other side of Dee. She watched him move next to her and immediately took hold of his long, hard, thick cock.
As her hand moved up and down the length of it she said, "Very nice, very nice indeed."
Danny reached across with his right hand to cup Dee's right tit. She leaned toward him and soon their tongues were darting in and out of each other's mouths.
