My name is Stephanie, I'm 28 years old, blonde hair, 5' 8" and weigh about 130. My breasts are 34C, and I sometimes wish I had my sisters boobs, she is more like a 36D. I really shouldn't be concerned with such things I suppose, because I've never lacked for appreciative looks from the guys.
I've been divorced for about eight months, my ex and I have no children and after a four year marriage we both realized the spark was gone, the fire burned out. My sister and her husband have let me know I'm always welcome at their house, and I've spent numerous Saturday afternoons there.
My sister, Beth, is a bit shorter than me and weighs ten pounds or so more than me, and her husband, Mike, is a total hunk in my opinion! I've told Beth a few times that I think her hubby is just hot, and she smiled on one occasion as she said, "He is, isn't he? Sometimes I wonder if I can keep up with him!"
We laughed and I said, "Let me know if you need help with that!" It was basically a comment made in passing, but I have fantasized a time or two about being with Mike. Beth has commented favorably a time or two about the size of his penis, and the first time she used that word I interrupted her and said, "Don't you mean 'cock'? and I giggled.
She blushed a little and replied, "Ladies aren't suppose to talk like that are we?"
"Come on Beth!" I responded, "A good wife isn't always a lady in the bedroom, right?"
"Okay you're right! So he has a big dick, is that how I should say it?" she said with a smile.
"How big is it?" Holding my index fingers about six inches apart I continued, "Is it longer than this? Is it thick?"
"You're terrible Sis." She laughed and blushed again before saying, "Okay you have to keep this to yourself alright? I measured it sometime ago with my sewing tape-measure, and it's seven inches long and nearly six inches around. Satisfied?"
I laughed and said, "Pretty sure I would be with something like that to play with! My ex wasn't quite that well endowed, he only had about five inches and not very thick so our sex life wasn't the greatest!"
Several weeks later we all went to the beach of a beautiful lake nearby and I chose a pretty skimpy bikini. Beth was also in a bikini, but a somewhat more modest version. And Mike.. Mike was in something much like a Speedo, and he certainly looked good in it!
Mike's friend Rob came with us and he brought his 3 seat Jet-ski along. The guys each took a turn on it and then Mike asked me if I wanted to go for a ride with him, which I readily accepted. I sat close behind him as we accelerated away from the shore, with my arms around his chest. Soon we were cruising along at a sedate 35mph and I casually slid my right hand down his thigh and trailed my fingers up the inside of his thigh.
I repeated this several times and then he softly clenched my hand and paced it directly on his cock, which was hard already. He slowed to almost idle speed and said, "Not sure what your intentions were Steph, but you certainly have me aroused!"
I replied, "I just wanted to see if your cock is as big as it looks in your swimsuit! It is, and it feels great! Beth is a lucky woman!"
He replied, "Thank you, I'm a lucky man as well! Would you care to drive this thing back to shore?"
"Heck yes I would! How do we switch positions?"
He answered, "I'm gonna stop this thing, shut it off, and fall off the side. Then you move forward, I'll climb on behind you, and walk you thru how to drive, okay?"
Before I could respond he leaned to the left and glided into the water. Two seconds later he was pulling himself up on the rear of the ski. He leaned in close and instructed me on the mechanics of operating the craft and we got underway. I wasn't nearly as aggressive as he was piloting the jet-ski, but I was having a blast!
I had headed away from shore at an angle and when I turned to come back Mike ran his fingers down my right thigh, as I had done to him, and then trailed his fingers up the inside of my thigh all the way to the crotch of my bikini! What a pleasant distraction this was! We were within 300 feet of the beach and I turned 45 degrees right for a bit, then 45 degrees left, and then turned sharp right again and gassed it, throwing both of us from the ski!
The jet-ski automatically started circling and as we were laughing out loud he climbed aboard and then helped me up. We eased up to the beach and as we dismounted I glanced at his swimsuit and verified his erection had diminished, and the only wetness I displayed was lake water!
On the way home from the lake we were talking about the fun we had and Beth turned and looked at me and asked, "Steph did you have a fun ride on the jet-ski? You both were sure smiling when you got back!"
"Yes, I did! Those things are a blast!" I glanced at Mike in the rearview mirror for less than a second and continued, "But Beth I have a small confession to make. When I was riding behind Mike I had let go with my right hand to get my hair away from my face and we hit the wake from a boat as I reached forward to hang on to Mike again. He swerved left and my hand found his crotch instead of his chest. I accidently grabbed his penis!"
She spun in the seat and was practically laughing at me as she said, "Was it hard to hold on little sister?" Looking at Mike she asked, "Honey are you okay? Was it hard for you to maintain control?"
It was all I could do not to laugh, and Mike started coughing as if he were choking.
The following week a new Gym was scheduled to open, and they had mailed out coupons hoping to sign a plethora of new members. Beth called and invited me to go with her and check it out. We enjoyed a nice workout and hit the showers afterwards. We were the only two in the showers, and Beth noticed my lack of pubic hair and asked, "Do you shave down there or do you have it waxed?"
