It starts with my SIL and her husband are saving to get a mortgage, it’s been a while but they are in the home stretch. So recently my wife and her sister were talking about it, she asked us if we can lent her €8000. They will pay us back over time, they have in the past so I have no problem lending the money. My wife talked to me about it seeing as it is mostly my funds going to them. My wife thanked me for helping them out, I told her we all help each other out when in need.

The next day I took out the funds, to drop off at my SIL’s place. When I got there she invited me in like normal, asking if I wanna stay for some tea and biscuits. I accepted as I walk in, I see she’s just in a robe maybe just out of the shower or something. She’s got quite the body so I watch her ass as she walks in front of me. Talking to her as we walk in, I see the place is quiet. She tells me the husband brought the kids to their friends down in the country side for the weekend.

I joke with her that it must be nice having a quiet house all to herself, she smiled while telling me I can’t imagine how good it is. We joke like normal till I get up to place my cup in the washer, she’s tells me to sit down as I’m the guest so she will clean. As she leaned down to pick up the cup, I could see her breasts in full view. She looked up into my eyes, as my eyes are fixated on her breasts. She asked me “would you like some more?” Yes please I say as I remember stuttering a little.

A few minutes later as she comes back with a fresh tea for me, she asked me about the money so I give it to her. With a smile she thanks me but I see tears forming, I asked her what’s wrong. She tells me I have no idea how much this means to them, I tell her I do know and she is family. She knows it’s mostly my money, so after talking and consoling her for a few moments. She asks me can I keep a secret, I tell her of course. She tells me that she knows paying back the money isn’t worth anything.

Then with a slight smile and pause she asks me can she thank me in a different way, I say okay so she stood there in front of me. Undoing her robe letting it fall to the ground, exposing her whole body to me. She tells me she has always known I liked her it flattered her how I would look at her. With lust but also restraint. As I take in all of her body, I take off my pants to show her how hard I was looking at her. Then slowly walking and lowering herself down to my lap she looks at my hard cock, knowing she is about to suck on it. While looking into my eyes she slowly took every inch of my cock in her mouth, after moments she was wet from drooling on my cock. I was in heaven the whole time watching her, then I asked her if I can fuck her.

Then she stood up climbing onto the couch, straddling on my cock, as she slowly took my cock inside her. Her pussy felt incredible. Being so wet already my cock just slid right in to the hilt, she moaned so much as she began to ride my cock. So I told her this is be a secret, she agreed. Then she began to say how no idea her sister has a happy sex life, then I told her how her husband is a lucky man to be fucking a pussy like hers and having a woman like her. This type of teasing went on for a few minutes, but as I got close I told her.

Knowing that she then begged me to cum inside her, I agreed. As she then tells me how she is gonna make me cum inside her, I tell her make me then. As she clenched for muscles while refusing to stop or get up off me. She bounced on my cock to hard and fast she made sure I came. While making sure she got every drop from me. As I say there exhausted while my cock in still inside her cum filled pussy, she looked at me smiled then proceeded to French kiss me. We kissed for a good while as cock went from hard to soft to getting hard again, as we kissed she began to slowly grind on my cock till it slipped out. After that we both got up and cleaned ourselves. Then after getting dressed, we agreed that will be our secret.

As I was leaving she gave me a big long hug, I had my hands on my waist and ass. Then I slapped her as being naughty, then she started to kiss me before pushing me a little saying that’s enough for now. While a cheeky smile. As I left I was in awe of what had just happened.
