I was staying at ski resort, in the off-season, on a business trip. There is an outdoor heated pool, with a large jacuzzi adjacent. I gave it a try in the evening, noticing that the bubbles & stimulation were quite vigorous,and I quickly got very hard. Especially exciting was the fact that there were plenty of people around, but no one could see how stimulated I was. I made a mental note for the next day!
I planned on going in as soon as it opened, 7:00 a.m, figuring I'd be alone. But it was popular; there were already a few families playing in the pool. I had removed the liner to my rather loose trunks, so the strongly churning water entered the leg, buffeted and bobbled my erection randomly & deliciously. A lovely experience: to be so secretly stimulated, while apparently behaving myself with hands above water!
A lady entered the opposite corner of the tub. She was very serious & dignified maybe about 30. Now, I'm of the opinion that MANY people are sexually stimulated by jacuzzis, but few, especially women, will admit it. It's one of those 'polite fictions': plenty of people do it, but nobody talks about it. We all just act dignified, and secretly cum underwater! I acted casual, minded my business,but kept a keen eye on the lady, as I enjoyed my own pleasure, looking for any unusual sign. She held onto the edge of the pool, stretched out, and floated on her back, eyes closed, in her own relaxed world. I thought, 'if this tub is so stimulating to a 7' penis, what must it do to a clitoris? Would she? The slightest sign from her would have sent me over the edge. But then Hubby came over to her from the pool, and she got out. Damn!
I have, however, had many orgasms in hot tubs. I strongly recommend them for masturbation-anyone is bound to find a 'good spot'.
