Sue was on a temporary assignment in San Diego and I flew out for a visit. A couple of days after I arrived we decided to spend the afternoon at the beach. When we arrived at the beach we found a place well away from other sun-lovers and put up a small windbreak to ensure our privacy and to protect us from the slight breeze. Sue stripped down to her traditional turquoise bikini and stretched out to take in the rays. I stripped down to my swimming trunks and got out a book to read. We both applied some sun tan lotion and settled down for the day.
After about half an hour Sue turned over from her back onto her stomach and asked me to rub lotion on her back. I applied a few drops to her back and started gently massage it into her skin. I was straddling her bum and leaning forward to reach her shoulders, which caused my penis to rub against her. Sue asked me to undo her bikini top so that she wouldn't have any tan lines across her back. I was happy to oblige as it meant that her bikini top fell away from the sides of her breasts and, after more than fifteen years together, I still enjoy looking at Sue's uncovered body.
I started to get an erection so I decided to move to Sue's left side, positioning myself so that I could see if anyone approached us. I concentrated on the her back but every now and then I would rub lotion over the sides of Sue's breasts. After five minutes of this I took the opportunity to tease my hand under her to cup her right breast and gently tweak her nipple. This elicited a soft moan from Sue so I did the same to her left breast. Sue refused to lift her body and without her help tweaking her nipples wasn't particularly easy so eventually I decided to switch my attention. I put more lotion on my hands and gently applied it from her shoulders to the base of her spine where her bikini bottoms started.
I dribbled some more lotion just above her bikini bottoms then, lifting her bikini with my left hand, rubbed the lotion into her bum cheeks. When I did that her legs parted slightly, which I took as an invitation to slide my middle finger down the crease of her bum to her labia. This elicited another moan and further spreading of her legs and that allowed me to insert my finger into her vagina. I inserted a second finger then withdrew them both and spread the moisture around her lips. I then reached slightly further until my fingers came into contact with her clitoris. At that, Sue moaned again and spread her legs further.
I decided to change my approach and took my hands out of her bikini. Sue whimpered at the loss of stimulation but then I attacked from another direction, moving her bikini bottoms aside so that I could use both hands on her vagina. With my left hand I reached down and spread her outer lips then I ran the fingers of my right hand through the moisture and onto her clitoris. I gently rubbed her clit and before long she was moving her hips and lifting her bottom to press against my fingers. I slipped two fingers of my left hand inside her vagina and that sent her over the edge. She can be quite noisy when she orgasms but somehow Sue had enough presence of mind to remember that we were on a beach and just moaned into the sand.
