"You lost a bet for me."
"Well, I certainly didn't mean to," I said. "What was the bet?"
"I bet Janet that you wouldn't look as big when you got out of the pool as you did when you got in. You know," she blushed even more, "down there."
"Oh. Well, I'm sorry to disappoint you."
"You didn't disappoint. Quite the opposite, in fact. But I still lost. So here."
And with that she slipped off her bikini top and pulled off her bikini bottoms and gave them to me.
"Thank you," I said. "What I am I supposed to do with this?" She was sitting to my left, so I put the bikini on the edge of the Jacuzzi near my right hand.
"Well that's up to you. The bet was that I had to give you my swim suit if I lost." If it was possible, she blushed even more.
"I see. And now you need to know if I'm going to give you the suit back or if you're going to have to walk naked back to the locker room, right?" My prick was starting to stiffen in my swim suit as I stared at this beautiful, naked woman next to me.
She was under water almost to her shoulders, so I couldn't see much besides the tops of her breasts, but just knowing that she was naked here with me was getting me pretty fired up down below. I looked up over my shoulder at the bar, and every single women in it was watching what was going on in the Jaccuzi.
"That's about right. Just to satisfy my curiosity, though, do you mind telling me exactly how big you are, uh, down there? You don't have to tell me, but since I lost the bet, I have to admit that my curiosity is getting the better of me."
"Well, I'm not going to tell you," I said.
"You must think I'm a total slut. But honestly, I've never done anything like this before. If you want me to leave, just say so."
"I said I'm not going to tell you, but I'm not exactly in a hurry to tell a beautiful naked woman to go away, either. How about this - if you tell me your name, I'll show you."
"Oh. I forgot I never told you. It's Michelle."
"Well hi, Michelle, I'm Dan. Pleased to meet you." I reached out my hand to her.
She reached hers out to shake mine and one of her nipples floated above the water line for just an instant. My prick was hard as a rock now, and I slid my suit down to my feet, so that she could touch it. "Here, you can feel my size for yourself."
I guided her hand down to my dick and I could feel her arm jerk just a little when she touched me. Then she got a little bolder and wrapped her hand around the shaft. Under the water and out of sight of anyone else, she ran her hand up and down my shaft from the root to the tip and back again.
It felt heavenly. I hadn't had anyone's hand on my dick besides mine in months.
"Holy cow, it's huge!" She continued to stroke my dick up and down and even cupped my balls in her palm.
"You'd better stop that soon, or I'm going to come." I said.
"Sorry. I got carried away." She said and pulled her hand away.
"No, that's okay. I just wanted to warn you that your hand feels very nice. Too nice, in fact. You don't have to stop touching it, if you don't want to."
Michelle put her hand back on me. "I've never felt one this big before. It's incredible."
"Thanks. You have a fantastic body yourself. You must work out a lot.
"Every day. I love keeping myself in shape. You look great too. Have you been coming here long?"
"No, I just started coming here a month ago. I worked out at home before that, but I needed the machines to tone my muscles the right way."
All the time we were talking she had her hand wrapped around my dick.
"I see. Well, Dan, what do you think I'm going to have to do to get my suit back? I'd really rather not walk out of here naked, if I can help it."
"At the same time, I'd rather not walk out of here with a hard-on. It's rather obvious in my suit, you know."
"Yes, I know. That's why I lost my bet. I was sure you were already hard when you dove into the pool. I had no idea that you would get even bigger."
"So that's the deal, then. You help me get rid of my hard-on and I'll give you your suit back. Fair?"
"Fair," she said, grinning mischievously. Then she swung around to face me in the Jacuzzi, her legs straddling mine, and put the head of my dick at the entrance to her pussy lips.
"Are you sure you want to do this? It's not exactly going to be lost on your friends what we're doing."
"There's no way I'm letting this thing get away without seeing what it feels like from the inside. If my friends want to watch, they can.
They can't see anything from there anyway." And with that she started to slide down my dick. Inch by inch she slid it into her pussy, pulling back up occasionally so that she could slide down a little more.
It took her almost a full minute to get it all in, but she managed it.
"Oh my God, I'm so full. You feel wonderful." She started to sway back and forth on my dick, keeping it buried in her cunt.
At the same time, I was busy enjoying the stretched-tight walls of her cunt. I'd never felt anyone as tight as her before. She felt custom-fit for my dick.
After she got used to my size, she started to lift up off my dick and then slide back down.
When she did, her beautiful little tits came into view and I started playing with her nipples as she rode me, pinching and pulling them.
"Oh God, oh God. You're so big. I'm so full. Oh God, I'm cumming already." Michelle gave a delightful little squeal and shook all over, inside and outside as she came.
She rested a minute and then stared at me and said, "Okay, your turn. Time for you to come." And she lifted up almost to the tip of my dick and slammed herself down over and over.
I'd never had sex with a dick like this and it felt great. She was going to make me cum pretty quickly like that and from the look on her face, that was exactly what she wanted. In no time at all, I was telling her, "I'm gonna cum, I'm gonna cum."
"Do it. Cum in me. Fill me up with that monster prick of yours."
"Here it comes..." I cut loose with the biggest orgasm of my life my dick twitched and shook inside her as torrents of come flooded out of my dick.
"Ahhhhh," she shouted as she came again right through my orgasm. She stopped riding me and just sat there in my lap facing me with my softening dick still inside her. She looked at me and then kissed me for the first time.
"Thank you. That was the best orgasm I ever had. Janet is going to be so jealous that she didn't lose the bet."
"It was great for me too. I haven't cum that hard in years. I think you've earned this," I said as I tossed her suit back to her.
"Thanks," she said as she pulled up her bikini bottoms. "Do you want to get a drink at the bar?"
"I'd love to," I said as I pulled up my Speedo and she tied her bikini top back on. "Let me get dressed and I'll join you in ten minutes."
"Great. I'll go dry off and meet you there." She stood up to get out and was greeted with a standing ovation from her friends at the bar. She blushed again and ran off to the locker room to dry off.
I gave the spectators a mock bow and headed off to the men's locker room to the sounds of hoots and catcalls from Michelle's friends.
So far, my plan had exceeded expectations. I could hardly wait to see what round two would bring.
