In the underground hot spring cave, my best friend's horny sounds echoed off the walls.

The man next to me leaned in close, his hand creating ripples beneath the water.

He whispered in my ear: "Hear that? Your friend's having fun. Want to experience it yourself?"

……………………………………

I'd been sleeping in separate rooms from my husband Tyler lately. Without intimacy in my life, everything felt dull and lifeless.

Hannah dragged me into an outdoor adventure group, claiming some excitement would help me rediscover my zest for life.

Trusting Hannah, I agreed to join a cave exploration that weekend.

But when I saw the outfit Hannah brought me, I hesitated. "Hannah, are you sure this is appropriate for outdoor activities?"

Hannah stripped off her jacket, revealing a black and red lace bikini underneath. "Lisa, I heard there's a natural hot spring in the cave. Usually, you'd pay a fortune at a spa for this - today it's free!"

After some convincing, I changed into the sexy swimsuit. Hannah playfully pinched my breast, making me gasp softly - it had been so long since anyone touched me.

Hannah teased that I was like a cat in heat.

I looked down at myself - my soft skin, full breasts, and slim waist.

Hannah sighed, "It's such a waste for someone like you to stay loyal to just one man."

I laughed awkwardly, sensing a hidden meaning in her words.

A Jeep approached us, kicking up dust as it came to a stop.

Two men and a woman stepped out.

"That's Roy, the group leader, Tristan, his deputy, and Vicky, Tristan's girlfriend," Hannah explained.

Following Hannah's gesture, I watched as one of the handsome guys changed clothes, completely comfortable with us watching.

As he pulled off his shirt, his tight abs were on full display. The perfect V-line disappeared into his waistband, drawing my gaze.

God, what a body! If Tyler looked like that, I wouldn't be giving him the cold shoulder - I'd be all over him every night.

Thinking of Tyler made me sigh. He never lasted long anymore, often finishing before I felt anything. No romance, no foreplay - just straight to business. I couldn't feel any love in it.

"Penny for your thoughts?"

A gentle voice startled me. I looked up to find Roy studying me intently.

His gaze traveled over my body, as if trying to see right through me.

I turned away, wishing my husband could be more like him.

He asked me to bend forward, then pulled out some rope to secure around my waist. "This is for cave safety."

His voice was so gentle.
