Absolutely crazy morning with my wife’s sister

Every summer we visit my wife’s sister, she lives in Portugal by herself. She’s 2 years older than my wife and I and she’s not had a boyfriend in all the years that I know her.

This may we visit again with my son, my wife and her (sisters) mom (we live in Belgium). One evening, we had planned to go on an excursion with my wife, her mother and our son the next day. We didn’t sleep much and I decided to call it off but my wife, her mother, our son still decided they still wanted to go, so I stayed behind to catch up on some sleep. I had done most of the heavy lifting that night with our son waking up a lot. Her sister also didn’t want to last minute, so we knew both me and my wifes sister were gonna be alone for the day. Nothing we didn’t do before. We’ve spent loads of time together before.

So the morning came and my wife, her mother and son left for the day. I caught up on some sleep and decided to go for a shower a little later in the morning. To reach the bathroom, I needed to pass through the sisters bedroom (it’s a weird construction that is common in Portugal and spain). We’ve always had the rule to knock first, so I did. But i didn’t hear any response so I decided to open the door and go in slowly. She was asleep but woke up, we said hi, nothing weird or odd in the air yet. Until something caught my eye. On her nightstand were two sex toys, a silver dildo like vibrator and a satisfier. I recognized the satisfier first because my wife has one too. I hinted her sister (lets call her Elena from this point – not her real name) that she might want to put those away, with a smile on my face. She was super embarrassed and grabbed them away and apologised loads of times.

It wasn’t until I jumped in the shower that I figured we now share a pretty erotic but odd secret. And it got me super aroused actually. In the shower I had a crazy boner that I hadn’t had in a long time. And of course, Elena wanted to talk and clear the air right away and didn’t hesitate to open the shower door (still unable to see me though, couldn’t see her either) and start a chat. She felt really embarrased and I stressed that it was fine. It was quite a long conversation about how she lives by herself and didn’t focus on putting her toys away too much. But I was still extremely aroused and also wanted to be honest about that. So I mentioned it. She was very understanding but then suddenly moved away the shower curtain. There she was, in just a dark grey thong, and covering her boobs with her arm. She got to witness me bare naked at that point, with a raging boner. I don’t think I ever felt my heart beat faster than that moment and asked her what the hell she is doing. But she said: just shut up and jumped in the shower with me, still only wearing her thong. She started touching my dick and after a quick thought I just decided to let her do whatever. I’ve often wondered what her sex life would be like but never asked obviously. I could now also see her tits as she was using her arm and hand to jack me off.

This didn’t last long until she hinted to get out of the shower. She directed me into her bed and started sucking me off. It didn’t take long or we were in 69 position and I moved her wet thong to the side. It was not just wet from the shower but i could clearly see she was crazy aroused too or just had some fun before I entered her room, as a large string of grool stuck to her thong while I moved it to the side. I started licking and sucking her pussy and it tasted fucking phenomemal. I was so horny a this point and hinted her to go onto her back so I could fuck her. And I did. Long and hard strokes and it felt so good but so wrong at the same time. She then grabbed her silver vibrator and pushed it onto her clit.

Just a couple minutes later she had the wildest orgasm with loads of squirting and it made me even more aroused. I wasn’t done with her yet and she felt that. She asked if there was anything I liked and I told her to give me her dildo. I spat on it and very gently pushed it into her ass. She didn’t know what to think of it at first but decided to go with it. Next minute I was fucking her pussy while also using the dildo on her ass and she visibly loved it. Not much later she came again.

I then came inside her and it ended quickly. We laid side by side for a minute thinking what the hell just happened. We decided and promised not to ever mention it again and keep it secret.

This was a real experience. But I have to say, this happened 2 weeks ago and I still can’t comprehend what the hell happened that day. While it was a crazy and enjoyable experience, I cheated massively on my wife and feel really bad about it. I don’t think her sister and I can ever come clean about this though so I’ll have to live with it.

I just had to share this story to write things off my chest. I hope everyone finds it enjoyable!
