Fond memories of masturbating in public with my future wife.
Linda's (name changed) parents belonged to a private recreation club that had several small lakes for swimming, fishing and camping. We would all drive down there for a long day of laying on the sandy beach, swimming and barbaqueing. We were both 18 at the time of this fun day.
It was hot and sunny this Sunday in July and Linda and I were both standing in the water, which came up all the way to my neck. Her parents and hundreds more people were on the beach sunning themselves and talking. Lots more kids were in the shallow area having fun and splashing around. There weren't many people out in the deep end where we were. Her older sister and boyfriend were over near the diving board, 50 or so yards away and her younger brother and sister were on the beach playing in the sand.
We were both standing side by side facing the beach area talking. Now, I would get pretty horny in the water since both of us were half naked in our bathing suits and there was lots of bare skin to feel. I moved behind Linda and put my right hand on her right breast and felt a nice rock hard nipple under her bikini top. I knew she must have been pretty turned on too based on her erect nipple. So, I gave her a little nibble of a kiss on her neck and took my hand from outside her suit and went in for some direct hand on breast action under her bikini top. She smiled and let out a soft pleasing sigh. Then I moved my hand from her breast and went under her bikini bottom directly to her clit. I began to rub her, slowly at first, but then increasing the pace and pressure.
We had been masturbating each other regularly for about the last four months or so, so I knew she wouldn't object! She let out a low quiet moan and pressed her body back into mine with her ass crack lined up perfectly with my stiff dick. She said she couldn't believe how exciting it was that everybody could see us, but they couldn't see what were were doing. I continued to rub her clit and I was whispering in her ear to pretend that everyone on the beach, including her parents and siblings, could see what we were doing. I don't remember how long I continued to rub her but I knew when she was ready to cum. Her breathing would change to short inhaling breaths and her legs would stiffen and shake. I said to her 'Look at your Mom and Dad watching you cum, you bad little girl!' And with that, sure enough, she came and came hard, still facing the beach. She would always have at least two orgasms when we masturbated, so a few minutes later I put my hand in her bikini from behind and rubbed her clit in what I called a 'reach around'. She always liked the sensation of my hand and wrist against her ass while I rubbed her crotch. Within one or two minutes she exploded with another orgasm.
Now it was my turn. I pulled down my trunks to my thighs and began to stroke myself, still facing the beach and all those people. She turned around, faced me, and she moved slightly to my right but not fully behind me, facing the beach. Her right hand caressed my hard dick and she began slowly stroking. It didn't take long and I told her that I was going to cum. She slowed down a bit and told me to try to wait and make it last as long as I could. I couldn't do it and I let go with a forceful cum that just knocked my socks off! As she's stroking me while I come she says 'I wish I could see all of that cum squirting out of you!' Then to my surprise she says 'Just look at what Daddy's little girl is doing now!' At that point I began to realize that she liked the 'naughtiness' of what we were doing. She then moved around and thrust her tongue deep inside my mouth for a great kiss.
I always thought going down to the Beach Club with her family was a boring way to spend the day, but not since that day. After that day we would masturbate each other every time we went. Sometimes it would be too busy on Beach Lake and we would drive back into the rear of the property and find a secluded fishing lake and do it there.
Either way Beach days were never boring again and her parents didn't have a clue to what we were enjoying.
