It’s summer, the weather is hot. The kind of heat you get really sweaty from which makes the body wet and shiny.
I’m in a small village on vacation. The village where my wife grows up and where my in-laws also vacation. The days are mostly spent hiking in the mountains, long and heavy hikes followed by swimming. Either on the mountain in a small lake or by the sea when we have come down again. On the farm where we live there’s a larger garage where I have made a small gym for myself. This day my wife and in-laws were going into town on various errands and were going to be away for a while. I went to the garage to exercise a little. Shortly after, my wife’s little sister came in and wondered if she could join. It was no problem for me.
Little sister Ashley is not exactly ugly to look at, especially not in a small tight hipster and bra. Since a late dinner a few days ago, a tension had built up between us. During dinner we had drunk some alcohol and at the table I felt some delicious bare feet that lay in my lap and massaged my cock. The surprise was great when my wife got up and started clearing the table while the feet continued to massage my now hard cock. I looked at Ashley and she looked at me with a devilish smile before she took her feet down. I was so hard and horny that I had to sit at the table for 30 minutes before I could walk.
Back in the garage we were done warming up, sweat dripping and I could see Ashley’s stiff nipples sticking out through the wet bra. We agreed to run a session with various exercises where the first to complete won and could decide a penalty for the loser. After about 25 minutes of sweating and pain, Ashley was done and crushed me. I had opened too hard and spat halfway.
It was a deserved victory and I was ready to take my punishment. The punishment was to give my sister-in-law a full body massage for at least 1 hour. Ashley looked at me with a teasing look, walked over to a bench, took off her shoes and socks and lay down on it. I walked over and looked at her sweaty little body lying on the table wearing only a transparent bra soaked in sweat and a tight hipster that I could see the lips of her pussy through. She stuck one foot up and it glistened with sweat running down her foot. Her feet were well groomed and she wore a red nail polish that were incredibly sexy. I grabbed her sweaty foot and started massaging it. Then she suddenly said, “yeah, and the punishment is that you must massage me only with the use of your tongue”.
Without protest, I pulled her foot up to my mouth and put my tongue on her sweaty sole. I could smell and taste the sweat but it just made me hornier. I licked her sole and sucked on her toes. First on one foot, then the other. It did not take long before she writhed in pleasure and moaned lightly.
It did not take long before I started licking her sweaty legs. Licked my way down to her pussy. She put her hand into the hipster and I could see 2 fingers starting to finger inside there. I took off her wet tights and could smell her delicious sweaty pussy. I licked my way down and started teasing around the area for a while before she could not wait any longer. She grabbed my hair and pulled me towards her pussy. I landed with my tongue first and felt her delicious pussy juice. I massaged her clit with my tongue while fingering her hole. It did not take long before she came and squirted all over my face. She got up and took off my shorts. There she found my rock hard cock and started working me. Licked the top of the head and bit a little teasing it. Just enough to hurt a little, but it was too good to stop. She took my whole cock deeper and deeper down her throat before the whole went down and she suffocated a little. She finished licking my balls and I was close to coming. I turned her around and laid her with her stomach on the table so that her ass protruded. I put my hands on her ass balls and spread them and planted my tongue right in her asshole. I licked and fingered the asshole until it was wet n ready.
I could not wait any longer and penetrated her anal with my cock. At first, the hole was a bit narrow, working to get the cock head in, but with the help of a little tongue and saliva, it started to slide better. I could feel Ashley having a new orgasm when it suddenly squirted out of her pussy. I stuck my whole cock into her anal and felt a couple of moans of pain. I did not care and increased the pace. Went harder and deeper before I exploded a large load into her asshole
