My first experience...Part 1

A number of years ago my then-wife and I had dinner at a bar/restaurant and ran into a couple we knew. My then-wife was a petite brunette with large tits and enjoyed all aspects of sex and the occasional cocktail. His wife was a stunning blonde, taller than my ex, with an incredible figure and green eyes. He was a super nice guy, older than all of us, and a bit on the heavy side, but very funny and fun to be around. After we finished our dinner, we agreed to meet them for a drink in the bar. Well, as occasionally happens, we all started chatting and one drink led to another and it was nearly closing time. We were all having a good time so he suggested we come to their place and continue to party. It was a cold January day and he mentioned we should all have a cocktail in their hot tub. He said there was only one rule; no clothing allowed in the tub...as his wife shook her head in agreement. I looked at my wife and she just smiled. I'm guessing the drinks helped diminish our inhibitions and I, personally, have never been shy about getting naked. We arrived at their place, just minutes away, and before I can get my jacket off, his wife has stripped and walks right by me heading to the tub outside. I couldn't help but notice how hot her gorgeous ass was. I hadn't even taken my jeans off and I could already feel myself getting hard. I remember specifically trying to think my erection away, as I didn't want to piss off my wife before we even got to the tub...it didn't work...but surprisingly, either she didn't see or didn't mind my semi-erect cock. His wife, my wife and I were naked, in the warm water in seconds as he prepared our drinks to order. As he brought them out, I couldn't help but notice he was indeed kind of heavy and had a relatively small cock. I'm not swinging a bat by any means, but since I got involved in this lifestyle, other wives and girlfriends have mentioned how much they enjoy the thickness and shape of the head of my cock. I'd call my length average to just slightly above average. He finally jumps in and immediately we're back to laughing and having a good time. My wife would occasionally run her hand up my thigh, under the water and rub my balls, leading to the occasional stroke...getting me harder as I look at his wife's green eyes, bright smile and perfect tits with the most perfect, erect, pink nipples. I would run my hand up my wife's thigh, pausing to tickle her clit now and then. His wife, starts talking about my wife's huge tits and how she's feeling self conscious. I immediately tell her that hers are perfect, as I watch her grab both of hers then pause with one hand to slightly play with one nipple. My wife is ***** by this time, but not drunk. He jumps out to refill our drinks and when he returns, his wife, rather than sit hers on the ledge like the rest of us, stands and turns to place hers on the deck below, bending over and putting that gorgeous ass directly in my face. At that very instant my wife abruptly reaches for and feels my rock hard cock. I look at my wife's face to see her reaction and she just smiled and laughed. Believing I've got a green light, I test my theory by mentioning how warm I'm getting, when her husband says, "Yeah, that happens to us too. Just sit on the ledge for a moment and cool down, then get back in the water." So I stand, exposing to everybody my rock hard dick. His wife sees it, glances at me, then immediately returns her gaze to my obvious erection. (continued in Part 2)
