Last week for my birthday, my partner (27F) surprised me with tickets to a sauna and thermal bath. It’s basically a huge hot water pool coupled with multiple jacuzzis. My partner is usually conservative and doesn’t wear revealing swimwear but the locals are the opposite. I was getting a free show of the skimpiest of bikinis available on show especially with fine bodies. We were in the jacuzzi accompanied by another couple and I could literally see down the other girls cleavage. This gave me a serious boner in the water especially when the jets were low. When the jets were turned on, my partner got frisky and started teasing my cock more and pulled it out to but keeping under the jets. Once the jets turned off, she quickly pulled under my shorts.

Later in the night, I returned the favour by eating her out and then fucking her pussy till we both came together. It was a surreal experience and just fed more into my imagination about what’s there to offer if my partner wore more revealing clothes.
