Mike and I have been happily married and enjoying great sex for over ten years.
One night we were out in our hot tub. It's out in the backyard and very private. Sam, an old friend of Mike's who lives out of town now, phoned to say he was dropping over. We said we were out back and told him to come on over. In a short time we heard him let himself in and he came out to the back deck and to his surprise found us naked in the hot tub.
No one had ever come back there while we were naked in the hot tub. It was pretty exciting, and we hadn't even planned this. The jets were on and so was the underwater blue light. It was very obvious that we were fooling around under the water, right in front of Sam. My large breasts really float in the water, and he really couldn't help but see them. The tub was new and he had never been in it. We invited him to join us. At first he didn't want to, but since we were going to light up a doobie, he stuck around as we always get high together. I think he was very turned on just to be invited to be naked with both of us. He left his clothes in the house and grabbed a towel. We told him we wouldn't look as he got in, but I did take a quick, discreet peek. So here the three of us were, under the water, in the dark, sharing a joint, all together. I wasn't sure if Sam brushed his hand on my tits purposely when he passed the joint, but I didn't care. Mike was playing with my clit under the bubbles the whole time. I wasn't sure if Sam could tell that Mike was touching me down there or not. I was really getting hot knowing Mike was fingering me about 2' from Sam. I just let my tits float. I guess I wanted Sam to see them. He might have caught on when I closed my eyes and let out a loud moan.
Suddenly the jets shut off, and there was Mike with his finger in me. We should have been embarrassed, but we were enjoying teasing our horny buddy. We kept on playing and talking, getting hotter and hotter. Mike moved closer to me and was touching me all over, and Sam was stroking his dick.
I'm at the boiling point (in more ways than one) and got out of the hot tub. I put on a robe and got everybody drinks. The guys got out and put on towels, and we finished the joint out on the deck. It was pretty dark out there except for a candle. Mike was behind me, checking for my wet spot. Mike took his finger out of my pussy when I passed him the joint, and Mike passed it to Sam with my fresh juices on it, which Sam tasted when he sucked on the joint. It was getting pretty hot out there so we went inside. Since we had already made ourselves horny, the mood carried on inside. The three of us always stay up late talking, listening to music, and messing around. Mike and I were on the couch and Sam was in a chair across the room. I was careless with my robe, subconsciously on purpose. I know Sam was looking at my tits, and Mike and I were both enjoying it.
