My sister in-constabulary, Susan, has been staying with usa for around a month and half now while her house is getting renovated.

My wife and I have a great relationship with her, so it hadn't been an issue when she asked if she could come stay with us. She's a few years younger than the states — my wife and I are both in our late twenties.

Generally, it was fun having her effectually as she made united states of america practise the things we don't usually do. Such as staying upwards late, having some drinks and talking, and going out together. Merely basically stuff we don't bother doing when it was just me and my wife.

One dark, we were up late talking equally usual. At some indicate, my wife left us and went to bed, leaving the two of usa alone. We kept talking and soon, the topic drifted to sex.

My sister-in-law started request the things we enjoyed during sexual practice and if my wife and I had any kinks.

My wife isn't the kinky type so there was nothing much to say about her.

She asked me what kinks I have and, feeling brave and tipsy, I told her one I've had bottled up since forever: Ass play.

I've always wanted it done to me and have never had a partner willing to.

She was surprised and asked if I ever told my married woman well-nigh it.

I told her no. My wife and I take never discussed it.

I felt a little odd the next morning, having told my undercover to my sister in-constabulary. I was worried she might endeavor and talk to my married woman nigh information technology.

A solar day or and so passed and nothing happened, so I started to relax simply decided not to indulge in whatsoever tardily nighttime chats alone with her again.

Last Tuesday morning, while in the shower getting fix for work, someone came into the bathroom, grabbed something and on their way out pinched my butt.

I assumed information technology was my married woman as she's washed things like that before.

I didn't notice out till I was virtually to leave and discovered my wife had already gone out since a long time and information technology could take only been my sis in-law.

I tried to brush information technology off as a harmless joke.

Next morning, while in the shower again, I heard the door open. I managed to peep this time and it was Susan.

Embarrassed, I asked if she needed anything.

She said she merely needed to catch her brush and she'd be on her way.

I went back to having my bathroom and tried not to make something out of aught.

But so again, every bit she was leaving, I felt a paw on my butt again, a quick clasp. I turned in time to encounter her hand withdrawing and heard the door close quickly behind her.

I rushed my bath, trying to catch her before she leaves simply by the time I was done she was gone.

My mind racing all day, I did not know what to do.

I decided I'd face her in the dark and tell her to finish and exist washed with it.

I waited till later dinner to get Susan alone after my wife had retired to bed. I told her she can't proceed doing that and that it is not right.

She apologized and said she wanted to give me some attention after the chat we had and thought this would exist a pocket-sized cheers for letting her stay with us.

The 3 of us accept always had a playful human relationship so this didn't seem too strange to hear. A picayune inappropriate simply forgivable, so I felt very relieved going to bed that dark and feeling glad I talked to her.

Thursday morning, I was in the shower again. I heard the door open and information technology was Susan again.

I'm sure my face showed some concern. She apologized and grabbed a brush and slid back out the door.

I relaxed and went dorsum to washing up.

Nix happened for the adjacent 2 days, so I figured she had given up.

The fourth day, however, while washing my hair in the bathroom, I heard the door open again.

I tried to rinse my eyes quickly enough to look, but by then she drew the shower drapery aside and I quickly turned and covered my naked self.

I asked her what she was doing.

She pushed me around and pressed her manus on my back. "Bend over," she whispered.

I hesitated, feeling confused.

She pushed me over again towards the wall and grabbed my body wash from the rack.

I asked her what she was trying to practise and she hushful me and told me to stop talking.

I heard a click as she lifted the cap of the body wash. And then I felt the liquid being poured into my butt crack.

I tried to stand upright, but she added some pressure level to my back and whispered that I should stay that way.

The adjacent thing I felt was her fingers within my ass crack.

She rubbed effectually a little and I started shaking.

I felt some pain when she slipped a finger into me. She and then started moving it in and out of me and the hurting soon turned to pleasure.

The feeling was incredible. I've done it to myself earlier but it was nothing like this when being done by some other person.

I put my easily on the wall to brace myself as she worked in and out of me with her finger.

She continued for at least five minutes and then whispered that I should start jerking off and cum.

It took no time at all for me to cum and I could experience myself contracting effectually her fingers.

When I finally stopped, she pulled her fingers out, airtight the mantle and left. All without a discussion.

I stayed aptitude over like that for another minute or so, before I came back to reality and finished my bath.

All twenty-four hour period at work that day, I was a mess.

I felt guilty and ashamed. More than a little emasculated and a niggling sore. Worst of it, I had no idea how to handle seeing her that night. I was scared that I was going to act really bad-mannered that my wife would find out.

Luckily, Susan came home that nighttime after we had settled in bed and I was glad. I had no intention of another confrontation similar the night before.

I tossed and turned all night on the bed, only finally falling asleep early in the morning. I woke upwards to a seemingly empty house and was more relieved to have some fourth dimension to think. I took my time eating, non certain who I should talk to showtime or at all.

I shouldn't keep this from my wife simply then letting this quietly go away felt like the all-time option. Susan would get out soon anyway so I could just let it get away.

I cleaned upwards after breakfast and made for the bathroom. While brushing my teeth, Susan entered.

I well-nigh dropped my toothbrush. I told her to exit, that I don't want to talk and I don't want her around.

"I'chiliad not going to say annihilation or apologize," she said to me. "Yous wanted it and the idea turned me on."

She aptitude toward my ears. "Get into the shower now and I will do it to you once again for the very last time and so go out y'all in peace."

I was more ashamed to say I did get into the shower.

She left while I started washing and soon came back into the bathroom and told me to curve over.

At that place was no hesitation this time. I turned effectually and pushed the shower nozzle away as she had done the morning before.

She had lube this time and the difference from the trunk wash was noticeable. She worked in ii fingers correct away, starting starting time at a slow pace.

I was shaking again. Weird and alien emotions ran through me — the thought of allowing this to happen again and the great pleasure I was getting from the human activity.

I don't know how long she did it for but she told me to wiggle off again and I started stroking.

Information technology took just seconds this time and I burst.

She held her fingers inside me till I was done and she pulled out and left.

I stood up and slowly done up.

Guilty and ashamed again, I came out of the shower with my mind racing.

I didn't know how I was going to stay the weekend without acting a picayune strange to my wife. Telling her about it floated in and out of my mind, but I couldn't attain a decision.

I felt guilty and fifty-fifty more terrible that I however get aroused each fourth dimension I call back about the incident.

I know this has to stop and information technology'southward lilliputian of me to potentially ruin relationships, multiple relationships in a family for some kink I've wanted.

I had to somehow get this off my chest and that'due south why I started typing this.

Because I'm writing this while my wife is out shopping and Susan will be home from work in similar half an hr, I've been thinking very deeply and feeling actually confused and scared.
