I wrote this 3 years ago.
I am a terrible person. I realize that. I have been screwing my wife's (Beth) sister (Amy) for the past few days and here I am writing out the explicit details rather seeking advice. But I already know what advice I'd get, and I can't help myself. This must be what it feels like to be addicted to coke or other high level drug.
Amy is divorced after being married for less than 2 years. She was renting a place on the west coast of Florida, but lost her job back in December and has not been able to find anything else. She decided to move closer to Beth and I in Miami, where she'd have a better chance at finding a job. She has been staying with us for over a month now. It was supposed to be for a week or two until she found her own apartment, but now with everyone in lockdown, she is stuck with us. We have a small 2 bedroom, 2 bath apartment and it is hard not to be in each other's way sometimes.
Amy is tall - around 6 foot - thin and a blonde bombshell. She exudes sexy and always wears provocative clothing. It's hard to keep your eyes off of her. Beth says she loves the attention. There has been a nice routine every day. I wake up first and cook breakfast. Amy is usually up next, sits at the table and chats with me. She wears super sexy nighties - not the kind of bland things my wife wears, but more like what you'd expect a wife to wear on a honeymoon. One is a flower print satin and the top fully shows off her cleavage and her nipples are visible behind the fabric. But this top is short and exposes her belly button. The bottoms are short too and cut high up the side of her legs. She has a few others that are similar but in solid colors. The others are more like negligees and come down to just above her crotch or just above her knees, but the ones that cover more actually have less material as they have lots of lacy parts. She wears sexy g-string panties with them. Maybe you find it odd a guy notices all the little details, but she only has a few with her and has to keep wearing them over and over. And they all make her look incredible and I look forward to seeing her in them every morning and at night. Beth is up last and we all eat breakfast. Before, Beth and I would go into work, but now we are working from home. Now, after breakfast, I sit at the table with my laptop and work. Beth works on the computer in our bedroom. And Amy usually gives me a show. She does yoga in the living room because the guest bedroom is too small. She wears a sports bra and yoga pants that are so tight she has a huge camel toe. The way I sit at the table, I can see her from the corner of my eye, and I have to sneak looks when I know she can't see me. I have a hard on the entire time she's doing her various poses and I'm thinking of fucking her in every one. She has to know how erotic she looks doing some of those poses in those pants.
After Yoga, she takes a shower and I can clearly see the bathroom door from the table. She comes out of the bathroom with a towel wrapped around her but does not fully cover her crotch. I sometimes get a nice view. Finally, she usually comes out dressed in shorts or a short skirt and tube top or whatever it is called that just covers her breasts but leaves the midriff open. Or she has some low cut blouse on. Regardless. You get the picture. She is showing lots of skin and it has been driving me crazy.
Over the last 2 weeks, her flirting had gone up a notch. She bumped her hip into mine when I was standing in the kitchen and said good morning. Then she started leaving the bedroom door open a crack when she'd change or take a nap - trust me, it had been closed the weeks before. Several days ago, she sniffed my neck and commented on my cologne. All this was done when Beth was not in the room. Once last week when Beth was in the shower, Amy made a point to tell me she was doing some laundry because she didn't have any underwear left. It's not just what she said, but how she said it - with a naughty kind of smile. She was wearing a very short skirt and I wondered if she had any panties on - of course, that was her point. It was driving me mad. It didn't take long for her to show me she was not wearing any. She walked into the bathroom and bent down to pick up some dirty laundry on the floor and I had a perfect view of her clean shaven pussy. During the day, I had other opportunities to see her naked pussy - when she squatted to clean up spilled coffe on the floor and when she sat down in a chair facing me.
