The Swim Coach

Chapter 3

"Wow. That was... nice. Is your thing hard because of me? It's so big!" she went coyly. I admitted to her that yes she was the cause and "my thing" wasn't at full size yet. She probably has only seen her kid brother naked and no other guys. This was my chance. Under the calm pool surface, I grabbed her right hand and stuffed it into my trunks.

As her slim fingers made contact with my trimmed balls, my shaft started growing to its full glory. The head poked itself out from the top of my trunks, pressing against the palm of her small hand. She seemed unsure of what to do, so I grasped her hand from the outside of my trunks and guided her up and down.

She seemed to catch the hint and continued pumping my dick a few times. "Go ahead, feel everything. Don't be shy, just be gentle," I whispered into her ear. She loosened up a bit and played around with my balls with her fingers before wrapping her hand around the shaft and giving it a few quick pumps.

It was nice, but exploration was the name of the game. She seemed fascinated with my smooth, circumcised head and ran her fingers just under the cap, feeling every inch, including the pee hole.

The sound of footsteps approaching stirred us from our fun and Serena swiftly pulled out her hand from my trunks. A mature yet attractive woman wearing a black knee-length skirt, a sleeveless top, and a navy blazer approached the pool. She was probably in her late thirties and her body was well-maintained, with the tight skirt showing off her slim hips and curvy bottom. She looked quite familiar.

"Hi Mummy! This is Didi, my swim coach," Serena said. Damn! Serena's mum was a hot MILF! Observing her expensive-looking shoes, I took the opportunity to get out of the pool, flaunt my body a bit, and shake off some of the water, carefully before extending my hand. She looked at me from top to toe and exclaimed, "Hi! I'm Linda. You look very fit. Maybe I should start taking swimming lessons too," she said seductively while shaking my hand.

I saw Serena rolling her eyes, obviously catching on to the open flirting from her mother. But I remained cool, careful not to offend either party and keep my options open. "Thank you, ma'am. Your children are fast learners. I'm sure you wouldn't have any problems," I said tactfully.

She smiled and turned her attention to Serena, reminding her of her tuition class scheduled in a short while. "Just a quick reminder on my way home from work. Do take care of my little girl. She's looking good in MY bikini and she's growing up fast," Linda said with a twinkle in her eye.

I wondered if it evoked memories of her younger self. The bikini did look good on Serena, although it was loose in certain areas, no doubt because Linda was more well-endowed. But Serena had adjusted it nicely, so no free show for me. Linda bid us farewell and we were alone again as I got into the pool.

"So, do you think my mum is hot? Will you have sex with her if you could?" Serena suddenly went. I was dumbfounded at the sudden question. "Don't worry, my dad is not around. As usual, away on business, but we know he has another girlfriend overseas. I wonder why mummy hasn't found another guy" she went, deep in thought.

I pitied the girl and her family situation. Before I could come up with a suitable reply, Serena lunged at me and wrapped her arms around my broad shoulders. Pressing her breasts against my chest, she whispered into my ear, "But today you're mine, okay?" I chuckled in agreement.

"So, how was my thing? I went eagerly, eager to continue. "Wow, it's really big, can it fit inside me down there?" she asked, her curiosity evident. I felt myself getting aroused again at the prospect. After explaining to her in detail about her vagina expanding and lubrication, she seemed more at ease.

At the same time, I noticed her bikini top had loosened a bit just under the pool surface and caught a glimpse of her hardened left nipple, so pink and small. "Looks like you're getting aroused too," I remarked and softly grazed the outside of her bikini top, feeling the hard nipple through the thin padding.

At first, she looked shocked but then seemed to be enjoying it. I decided to take my chance and boldly put my entire hand into her loose bikini cup underwater. She didn't resist as I squeezed her small left breast, softly grabbing her nipple between my fingers.

After a few squeezes, I took out my hand and concentrated on her other breast. Her breathing got heavier and she just closed her eyes, enjoying the sensation underwater. After a few times switching from one breast to another, I decided to be bolder.

I reached down and grabbed her crotch from outside her bikini bottoms, pressing my middle and ring fingers against the depression of her pubic area. She grabbed my hand in protest, but parted her legs slightly, seemingly at odds with herself and what she wanted from me.

I gave another soft squeeze and she let out a soft moan, cocking her head backward. I was careful not to push it, being discreet as we were in public. After one more squeeze, she suddenly pulled my hand off her crotch. Just as I thought it was game over, she took my hand and placed it inside her bikini bottoms.

Her pubic area was totally hairless, so smooth and soft. I traced the folds of her pussy lips with my fingers and, even though we were underwater, I could still feel the thick, sticky liquid from within. I gently dug deeper with my middle finger and found the entrance to her love hole and her sensitive button.

At that angle, I couldn't insert even a bit of my finger, so I just played with the outside of her pussy and gently caressed the sides of her clit. She was in ecstasy and her hips started moving in tandem with my stroking. Just as I thought she was about to climax, she pulled my hand away from her bikini and pushed me away.

I looked at her curiously, wondering if she had ever experienced an orgasm before. Almost knowing what I was thinking, she exclaimed, "Wow! That's the nicest feeling I've ever had. But I have to stop because I suddenly felt like I had to pee." I explained to her that it was an orgasm and she should just let it happen, as it is the best feeling ever. Moreover, we were in the pool, so she had nothing to worry about.

Just as we were about to continue, the heavens disapproved and a flash of lightning accompanied by a loud clap of thunder came upon us. We quickly got out of the pool and collected our belongings from the beach chairs nearby. She hurried off first to the handicapped restroom while I made my way slowly to the changing room. I was certain that she would be coming for a shower soon and I was in a dilemma.
