This story happened about five years ago. It involves family but not incest. This will sound selfish but in fact I think it helped the family.
My oldest son was in one of the military branches stationed in North Carolina. He had a new girlfriend, or should I say, fiance with a child from a previous relationship. I decided to go visit. I stayed with them and found they had a roommate to share expenses. This was not a big problem she was almost never there. They also had a friend who babysat quite often and often stayed over. I was put up in my future granddaughter's room.
Around day three we decided to take a trip to the ocean. At this time I didn't realize the babysitter wasn't live in because she had been there the whole time. My future daughter in law who was pregnant with what would be their first together, wasn't a big beach fan but Skye the babysitter was. Skye was short, about five foot one, not skinny but not fat. She was solid with thick thighs,small round soft belly and firm round tits that weren't huge but looked so on her frame.
My son's fiance spent most of the day under an umbrella while the rest of us played in the ocean and sand. When Skye laid out in the sun face down I couldn't help stare at her beautiful dark tan body. Her bikini left little to the imagination. It was a string bikini with a thong bottom. She had been very flirty with my son in the water and even asked my son to rub lotion on her at one point. I found it very odd and a bit disturbing. My future daughter in law who I really liked and thought would suit him well was obviously upset.
We had a picnic lunch on the beach and things seemed to settle a bit. I went back in the water and Skye joined me. She began splashing and jumping around me. At this point I thought that she must just be one of those flirty type girls. Once back on the beach she sprawled out on the blanket looked at my son with my fiance. She must have thought twice about asking him to lotion her again, turned to me and asked me to rub lotion on her. I obliged.Now this girl had such a deep dark tan I couldn't imagine her needing sunblock. I could tell she had more than one bathing suit because she had tan lines that didn't match her suit.
I started up at her shoulders and began rubbing the lotion into her soft skin. As I worked my way down her back I got a handful of side boob, soft but firm. I started getting a bit nervous but very turned on. I glanced over towards my son but they were face down on another blanket with heads turned in the opposite direction. As I got to her legs her thighs parted a bit. Before I knew it I was kneeding her ass cheeks and she let out a few soft moans. I briefly brushed her slit and she moaned louder.
I had a raging hard on. I quickly finished and ran to the ocean to hide and deflate my hard as a rock cock. I thought about how close to cumming I came with this twenty something girl about thirty years younger then me.
We returned home and my daughter in law cleaned up her daughter and began preparing dinner. I was in the laundry room with my son and I gently brought up his flirting with Skye. He admitted he had feelings for her as well as his fiance. I almost got a bit angry but instead used my dad tone to talk about he had to make up his mind and choose and how it wasn't fair to Sara his fiance, who I told him I thought was a sweetheart and carrying my grandchild.
Soon we were in the living room chatting. Sara had dinner cooking and came in also. Skye made room for her by joining me on the love seat I was sitting on. She told me a bit about her background growing up in Kentucky and asked a lot of questions about me occasionally touching me as we chatted. By this point my daughter in law had returned to the kitchen and my son was absorbed in a video game. Soon Skye's feet were up in my lap and I was grazing her legs with my hand when I felt her rub her foot against my crotch.
Sara called for my son and when he didn't respond she came towards the living room. Suddenly Skye shifted and sat up. My son looked at the clock and announced that he had to take Skye home and said he'd be back in an hour. I looked puzzled when Skye mentioned that she had to go home to take care of pets. Sara looked perturbed. I suggested I take her and that he stay back with his girls. I was sure it wouldn't be a problem with gps.
