My brother bought an apartment, so I came here to celebrate his moving. My sister-in-law welcomed me with a smile along with my brother. It's been a while since I last met her, but she's a beautiful woman who looks great in glasses. However, I suddenly found out the secret. Cheers with a souvenir of sake. While the conversation was getting heated, my brother left his seat, so I started talking. ``The other day, I found an interesting video. I thought I'd like to watch it with you.'' ``What?'' What I showed on my smartphone was a video of my sister-in-law moaning and having sex. Yes, I discovered that my sister-in-law had appeared in an AV before getting married. "Please, don't tell me. I won't be able to live if you tell me we're breaking up..." Just then, the older brother comes back and the good drinks are flowing smoothly. I was completely crushed. "Sister-in-law, you can just keep quiet. Do you know what I should do instead? I want to do what you did in the video." She caressed her thighs and grabbed her breasts through her knit. With a sad expression on her face, she seemed to have made up her mind and took off her clothes, revealing only her underwear. ``Don't make a sound,'' she threatens, rubbing her breasts from behind and hitting her in the ear. When I rubbed her nipples, her body trembled, "Ugh..." ``I want to see my sister-in-law masturbating.'' ``I can't do that.'' Still, she timidly spreads her legs in an M-shape on the sofa and traces her panties. Then, a faint stain appeared. While worrying about my brother who was falling asleep, I ran my fingers further down. ``Next, take off your panties.'' I stand up and pull down my panties. ``Let's kiss.'' He snatches her lips. ``Sister-in-law, let me lick you.'' ``I can't...'' I don't care and start sucking on her already damp pussy. "Haa, haa, mmm," my sister-in-law said in a stifled voice as her breathing became increasingly labored. This time, try inserting your finger and moving it. "I'm going to cum" It seemed like he felt it. I stick out my penis, which has become big, in front of me and ask her to touch it. ``I want my sister-in-law to suck it in my mouth.'' With a puzzled look on her face, she begins to suck his dick. I'm also getting more and more horny. "Come here." We got into a position where we were licking each other on the sofa. My sister-in-law's pussy is being attacked while holding a dick in her mouth, and she's feeling trembled, saying, "No!" I was mean to him and made him put his hand on the front of his collapsed brother, and as he licked him from behind, the love juice began to seep out. ``Can I insert it?'' ``No, please stop.'' ``I've already inserted it.'' As I slowly begin to move my hips, ``Please, stop it already.'' As I say that, my body is honest. When I put a noise and hit my waist, I felt like raising my voice while worrying about my brother, "Uuh, oh, oh,". He held her from behind on the sofa and pushed her up to show his brother the joints. "Please, I'm going to wake up, so please stop." Her breathing became even heavier. I made her squat down in front of her and make her suck the dick that had been inserted into her pussy until now. "It feels better than your brother, doesn't it?" He shook his head while sucking it in his mouth. This time, I hold her in front of me and thrust into her even more in the ekiben style. She hugged me tightly and said, ``I'm going to cum,'' and I reached it. I pushed her onto the sofa and made her kneel on the floor and spread her ass. I could see her pussy and anus completely, and I made her say, ``Please insert it.'' Penetrate straight through. I knew I was raising my voice, so I covered my mouth. Looking at him like that, I'm almost at my limit. I laid her down on the floor and moved my hips while looking at my sister-in-law's expression. ``Sister-in-law, do you like me?'' She desperately shakes her head and denies it, but when we kiss her, she entwines our tongues firmly. "I can't do it anymore, aaaaaaaaaaaaa" "Sister-in-law, I'm cumming too. I'm cumming" I shot a thick drop of semen onto my glasses. ``Sister-in-law, I'll come visit you again.'' I left the room, leaving my sister-in-law breathless. I have to embrace my weaknesses and continue to enjoy myself even more.
