Love in the Time of COVID, or my affair with my sister in law [MF]

Okay, confession time: several months ago, I started having an affair with my Sister in law.

My wife’s older sister, Lisa, has been having marital problems for as long as I’ve known her. Her husband is rich as hell (family money, doesn’t do shit), and he acts like a perpetual adolescent in many ways. They have a five year old boy that he didn’t really want, and doesn’t really care about. Lisa met him when she was 18, (she’s 33 now) and my wife’s family was pretty poor, so I think all the money and overseas trips dazzled her. But he always jokes that he “got her on sale.”

My wife and her sister are both very attractive, but since this is about Lisa I’ll focus on her. Lisa is about 5’7” and fit. She has dark hair, green eyes, a great smile, B cup tits, and a perfect round ass – definitely her best feature. It’s hard not to stare, especially at the beach. Seeing Lisa in a bikini is always a treat. She has amazing hipbones. She doesn’t work, so all she does is stay in shape and take care of their son. She has a runners body. She’s more athletic than my wife, who is very petite.

My wife and her sister are really close. We hang out with Lisa and her husband at least several times a month, and I get along with Lisa really well. (I’m nice to her husband but I don’t really give a shit about him – it’s clear he feels the same way about me. We tolerate each other.) I’m attentive and loving to my wife so Lisa always looked at me a little wistfully. She’s got money, but emotionally her husband is nonexistent. She’s mentioned several times that if her husband died, she’d move in with us and I’d get both sisters. It’s a joke but I always sensed a bit of truth to it. My wife always teased that Lisa has a crush on me. I always liked Lisa and for a long time thought of her as a sister. I was there when their son was born and I always like hanging out with her. She’s smart and funny but a bit insecure about herself – my wife is too. They’re both amazing women but have no idea. Lisa and I will text sometimes, and there’s been some sly flirting along with her sister-wives talk, but mostly we’ve kept everything above board.

My wife and Lisa are both very sexual. They’ve mentioned several times that they “experimented” a lot with each other when they were younger, but I never really pressed for details. They still shower together whenever they have overnights somewhere. Also, I know my wife has shown Lisa our sexting pics. (In the past they’ve actually exchanged sex tapes, but this was before my wife and I met, so I haven’t seen either of them.)

So this happened just before Christmas. Lisa was coming over a lot after my wife got out of work, and they’d sit on the couch and drink wine, and I’d go off somewhere to give them ‘sister time.’ Lisa was crying a lot, and my wife has been urging her to leave her husband. (My wife absolutely loathes him.) Around then Lisa was texting me more, but nothing really notable. She would just make random conversation, or she’d say things like, “I’m so happy you married my sister.” “I’m so lucky to have you as my BIL.” She never asked me to show her my dick or anything, and she never “accidentally” sent me nudes. I just thought maybe she was more lonely than usual, and I pursued my extra-curricular sex elsewhere.

One day I got a text from my wife. It was before noon and she was at work (I work from home due to COVID). Basically, my wife said Lisa was upset and she wanted to come over to crash and would it be okay. She knew I was working and that Lisa wouldn’t get in my way, she just needed a place to decompress. I said okay, and a few minutes later Lisa showed up. She looked like she’d been crying. I didn’t have much going on at work at the time, so I made coffee and we sat in the kitchen and I let her talk.

It was the usual stuff. Her husband didn’t care about her, she felt unloved. She was thinking about leaving him but didn’t think anyone would want her. I was very complimentary, just trying to cheer her up. I told her how fantastic she was, and how any guy would be lucky to have her, stuff like that. After a while she kind of mellowed out and could laugh a little. I remember she was wearing mom jeans and a big white sweater, nothing special.

But let’s be honest. My wife’s sister is over when my wife is not home. The situation did not escape me. I’m being a kind, warm, sensitive brother in law, but really all I’m thinking about is unbuttoning her jeans and bending her over the table.

Eventually we started flirting a little, just testing each other out. She said my wife was always talking about how good our sex life is. I said, “I’m a giver.” And she said, “Oh god I need a giver. I’m always giving but never getting. I’m always left feeling empty. And horny as fuck!”

There was this like, deep pause, where we were both thinking the same thing, but not looking at each other. My heart was pounding and I said, “Are you sure you’d want that?”

She understood what I was asking and smiled hesitantly. She said, “I wouldn’t want to hurt my sister.”

“Neither would I.”

She was nervous and she said, “I don’t know… What would you do?”

“I have always wanted to spread your legs and devour your pussy.”

She closed her eyes and smiled. “That’s funny because I’ve always wondered what it was like to fuck you,” she said.

After that I went around the table and we kissed for the first time. It was a little awkward at first, to be honest, because I’ve known her for so long. But after a few seconds we both sort of let go and attacked each other.

We made out standing in the kitchen for a bit, letting our hands explore each other. I remember it well, feeling her body for the first time. I reached under her sweater and felt her stomach, her ribs, the top of her bra. She kissed me fiercely. She is a very hard kisser. Very needful. As we were making out my heart was racing. I think we were both terrified but thrilled.

I unbuttoned her jeans and she leaned back on the table as I reached my hand inside and felt the outside of her panties. I could feel her soft mound under the cotton fabric. She leaned back on the table and I ran my fingers over the pussy. She’d pull away and gasp as I brushed her clit.

The kitchen was a little uncomfortable so we went to the living room. I sat on the sofa and she took off her clothes. She said she’d been wanting this for so long. I did too, and it was amazing to finally see her naked.

Her tits aren’t big but they look good with nice small nipples. When she pulled off her panties, I saw that she had a shaved pussy with just a strip of hair above. Right then I couldn’t take it anymore. I grabbed her, spun her around and laid her on the sofa. I opened her legs and I just devoured her pussy. She was gushing wet. I licked her up and down and she threw her head back and cried out and moaned. I love love love to go down on her. My wife doesn’t really care about getting her pussy eaten, but I love to do it. So with Lisa I really get to indulge. One of my favorite things to do is just push her legs back and fuck her with my tongue, as deep as I can get to her warm center. Her pussy is absolutely perfect. Thinking about it now just makes me salivate.

I don’t know how long I was at it but it was definitely a while. She let me lick those soft petals for as long as I wanted. She must’ve came five times before she was done. There was a big wet spot on the sofa, and her pussy and thighs were glistening.

I tore off my clothes and she told me to sit on the sofa. She wanted to ride me. I sat back and she straddled me and then slowly lowered herself onto my cock. Oh my god her pussy just slid around me, firm and warm. That feeling of a pussy around your cock is the greatest in the world. Not only that, but the taboo of my wife’s sister was incredible. I just kept thinking, holy shit, this is Lisa. This is your wife’s sister. You are fucking your wife’s sister!

She just went crazy. She put her hands on the sofa and just rode me like she hadn’t fucked in forever. I grabbed that perfect ass of hers and thrusted up as she slammed down over and over. She was crying out, eyes closed. I was kissing her neck, her chest, her tits, sucking her small nipples. I spanked her ass and she’d cry out in pleasure. I spanked her harder as she fucked me and every time she cried out and I could feel her pussy tighten around my cock. Pretty soon she was sweating and I could feel the slickness on her skin. I love that feeling, of a woman’s sweat from pure animal fucking.

Soon she asked me if I was going to cum and I told her I was close. She asked me how I wanted to cum and I said from behind. I wanted her on her knees and I wanted to see that perfect ass of hers. She said okay and jumped off and got on all fours on the sofa, bracing herself with her hands. I moved behind her and held her amazing bubbly ass. She just kept urging, fuck me, fucking cum inside me. I didn’t want to cum right away, so I behind her I fingered her slit a little. And spanked her some more. I pulled her back, reached around and played with her clit. Her body was slick and sweaty against mine and she felt so good I couldn’t really hold off any longer. All I needed was to cum. So I pushed her head down, inched her legs apart and slid my cock back inside her. She pushed back against me, moaning, and I grabbed her hips and fucked her as hard as I could. She cried out as I just used her wet little pussy. It was less than a minute before I was about to cum. I told her I was cumming and she hissed, cum in me, just fill me up with your cum. So I just slammed into her ass until I exploded as deep inside. I could feel it rush through me in waves. It was one of the greatest orgasms of my life. After that I collapsed on her. We were both just a sweaty mess. I slid out of her and we laid together on the sofa for a few minutes, catching our breath.

Then we cleaned up and got dressed. We both assured each other that it would be just between us. Now she comes over every few weeks or so, and we just fuck like mad in the afternoon. I’ve learned a lot more about her sexually. She really likes cum. Like, her favorite thing is to have me cum on her face and tits, which I’d never done before her. She also loves to ride, mostly from reverse cowgirl. I get to just lay back and watch her fuck me with that perfect ass of hers. A few times I’ve even fucked Lisa, and then my wife on the same day, which is really fucking hot.

I don’t know how long it’ll go on. We’re both extremely careful about our spouses. We don’t overly text or anything like that, so as not to rouse suspicions. But so far it’s pretty fucking great, but we’ll see how it goes…
