It all happened this summer! I never thought on my sister in law as a woman. She was always for me a sister, but everything changed on my holiday!
My wife and me planned to go on a beach after her sister told us that she, and her husband, were about to go to a rented house on the beach. They showed us the picture with that place and it was like in a dream. Let me tell you about my wife...she is 26 years old, a gorgeous brunette, long legs and an amazing round ass, shaped body since she use to work it on gym. Her sister is a red head, very generous big breast, same shaped body and legs you can't noticed how sexy they are. She is older than my wife, 32 years old, and married with a tall man, working on his private security business. We took my car, since it was a big 4x4 Land Rover, and sine my wife's sister was having car problems, she sat on front next to me.
She had a summer vaporous dress and you could see easy see her lingerie. By the way she sat there, I couldn't notice her sexy exposed legs and at some point she caught my eyes checking her. Like she wanted to tease me more, she raised a bit more her dress and let me see more.
We got to the house and first days we were just swimming, sat on sun and had wonderful time enjoying summer. After couple days of sun it starts to rain so we had to stay on the house, since the sea was also very whirling. It was boring first to watch TV together, eating pop-corn or playing cards. My wife was the first who bring the idea to play strip poker, since it wasn't so fun to play on chips. We all got fun when all of us start to lose, until we got to remain only on boxers and women had their top too.
My brother in law said at some point that it's not fair for ladies to have their bra on, and when my wife lost, her sister told her she have to remove her bra. I saw my brother-in-law looking at her breast but I wasn't jealous on that. I looked also at my sister-in-law's cleavage which exposed a very hot pair of breast. It was soon her turn to get rid on her bra and it start to get me hard not to stare at her beautiful breast. She had very sexy round nipples, hard and pink like raspberry, and she had that sweet perfume of peaches that start to arouse me. It was starting to get very sexual tensed situation and after we had nothing to remove, my wife's sister came with the proposal to play on punishments. It started to be very fun when again my wife lost and her sister had to give her the punishment.
She told her to write on the wall, with her ass, numbers from one to ten. The way she moved it was like she had a striping dance and I saw how my brother in law glanced lusting on her. Then my brother in law lost and my wife had to give him the punishment. She told him to have a striptease dance and she put a slow music. He first moved like a professional striper actually, and then he moved to his wife and danced like he gave her a lap dance. Soon after that he moved to my wife and gave her the same treat. I saw how turned on she was and at some point he even pushed his obvious hard bulge to my wife's bare breast. When the music stop he got back to his seat and he winked to my wife. Again my wife lost and brother in law had the biggest hand on poker.
He told my wife she has to massage his wife's tits until the music stop. She did that and we all laughed seeing her with the head between her sister's beautiful tits and massaging with her hands those round fruits. She wanted to have more and she even took a nipple on her mouth and played like she was sucking like a baby. I noticed how her sister loved that treat and the atmosphere got tensed. Then brother in law lost and his wife dare to him to give the same treat to my wife. He didn't hesitate and got on his knees in front of my wife and buried his head between her breast and his hands grab her breast and rub slowly her nipples with his palm. He got with his mouth on her nipples and sucked them very thirsty and did not hide how much he liked. His wife was laughed hard and told him to offer the same treat to the left breast too. I saw that my wife loved his attention too, but I wasn't angry for this situation, actually it turned me on. It was obviously the sexual arouse was getting us all.
When I lost next my wife gave me the dare to be folded on my eyes and to recognize only sucking the nipples I would get, which ones is hers and which one is her sister's. My mouth was drooling anticipating the flavor I want to feel from those sexy round breast of my sister in law. I noticed how sexy she was during those sunny days before and how wild is in bed, hearing her and her husband in their room having sex.
Then I got it first a sweet small nipple soft and getting very fast erect. It was my wife's one and the next was one the same. It didn't took me too much to see that was the other nipple of her. The third one was a bigger hard nipple, the perfume was for sure my sister in law's one, and the circle around it was swollen and bigger. I gave him a long loud suck and then I licked with my tongue the large circle. I took my time to do more of that and took in my mouth as much as I could her breast and sucked like a crazy. My wife said : hey...enough!
And I heard very loud laughed. Then after I got unfolded I told her the first two were hers and the last one was not sure but I guess it was her sister. She lied and said all three were hers, and I lost, and everyone was agree with her. When sister in law's lose next her husband told her to show me that I was wrong and to get from me a breast massage and a "special attention" for the next song. She got in front of me, and sat on the table letting me to offer her "punishment". I said with an innocent look it's not my punishment cause I wasn't loose, but I got right next having both hands on her breast. I gave her soft squeeze and massage, caressing her hard nipples and then I put my mouth on them and licking her nipples then I took one in my mouth and suck it. I recognize the same beautiful nipple I sucked before and I took my time to caress better her delicious breasts.
My wife said if I like them, and laughed too but I didn't stop feeling my sister in law getting pleased of that attention. She even took her tits in her hand and offered one by one to my mouth. I was really hard and I wanted so much to put my hard cock between those beautiful pairs of heaven, but I realized about that situation. I couldn't stop my moves and sucking one nipple I let my hands go down and grab her round ass. The music stop and we got back to the game. It was obvious that it was a very far gone situation and my wife said we have to have a limit, looking to me with that look: "stop that, and do not get carried away...". The cards were split and she lose with her hand. This time it was my turn to have a dare for her and she had to draw the same numbers from one to ten, but this time on her brother in law's lap.
She gave me a devilish look and got her place in his lap. He was very pleased about that and even his wife choose a song for that special draw. Having her ass in his lap she start to draw, and I saw many times she was like drawing wrong the numbers and moved again. She had a yellow pair of panty and we all could easy see the wet spot formed but no ones said a thing about that. When she finished, I saw how hard was my brother in law and for a bit I am sure I saw the head of his cock outside from his pants. He was for sure very close to cum, and moving his hard on under the table, and adjusting his voice he said...that was fun, and smiled. His wife gave him a punch in his arm like joking and looking to her hand she said with a big smile she is served. She had a full house and she already told my wife she have prepared the dare for the loser.
