My SIL showed up unannounced at my house and got an eyeful of my hard cock

I was cooking in the kitchen while wearing a robe when my sister in law showed up unannounced at my door. I let her in and she went to sit on the couch in our living room while we talked. Not going to lie, as soon as she showed up, I was instantly horny. The reality of us being alone together while I was naked under my loose fitting robe had my cock getting hard real quick.

From where she was sitting on the couch, she could see all of me too. My cock was pitching a huge tent in my robe and I knew she would be able to see it. So at first I tried to angle my body away from her so she wouldn’t see it, but after a couple minutes I decided I’d let her see the show.

I stopped turning my body away from her as much and gave her a view of my side profile instead. My cock was lifting my robe up, begging to be uncovered. I could see her eyes locked on my bulge while I cooked, nonchalantly. My cock, being bigger than average, would have been impossible for her to miss.

She didn’t mention it though. We just continued talking normally, like I wasn’t fully hard for her, wishing she’d come pull my cock out from under my robe and suck me off.

After a little while more of us chatting, she took off her jacket and revealed a small white crop top without a bra. Her nipples poked through the fabric and I could even see the dark outline of her nipples. It was almost too much for me to handle.

But it seemed like we were both sending each other a hidden message. You show me yours and I’ll show you mine. I was game.

While I was facing away from her, I pulled my robe to the side a small bit and my hard cock slipped out from underneath. Then I continued cooking like nothing was amiss.

She was in the middle of talking when I turned toward her. As soon as I did, she stuttered and stopped talking. My heart rate spiked and I suddenly got really nervous, but I calmly continued with what I was doing. After a moment, she kept going on with what she was talking about.

I commented occasionally on the story she was telling me. She seemed to have a lot of trouble telling it, taking long moments to think before going on. In reality, I knew she was just having trouble talking while my cock stood on proud display for her.

After a couple minutes of showing off, I hid my cock away under my robe again. It was starting to get softer anyway since it wasn’t being stimulated and my wife was going to be getting home soon. I’d need to put some real clothes on before she got home.

I left my SIL on the couch to go change and put on gym shorts and a t-shirt. I decided to forego the underwear though.

Back in the kitchen, I talked more with my SIL and finished the cooking. My wife got home a while later and we all ate. We had decided we were going to watch a movie that night so eventually the three of us all found our seats for the movie.

I was sitting on the couch with my SIL while my wife sat in our recliner chair off to the side. We were only about 15 minutes into the movie before I started to get really horny again.

We each had our own blankets so I was all covered up, but I could get around that. I brought my right knee up towards my chest so it would block my wife’s view into my lap if she turned around. Then I pulled the blanket tight over my leg, so it essentially formed a cave over my crotch with the mouth of the cave facing my SIL. She would have the perfect view to see right under my blanket and into my crotch.

My SIL glanced over at me while I was adjusting, no doubt spotting her new vantage. Her small glance instantly got the blood flowing to my cock and I found myself reaching down towards it. I grabbed my gym shorts and pulled them to the side, letting my cock and balls fall free.

And that’s how I left them. With the blanket open to my SIL and my cock out, she could glance over at any time to see it. The whole situation was so hot and risky, my cock was slowly getting harder without me needing to touch it… and my SIL noticed.

Her head turned towards me and her eyes looked down at my lap. I kept my eyes on the movie but internally, I was focused on getting hard for my SIL. It wasn’t long before my cock was standing up straight, rock solid.

My SIL hadn’t turned her head away from me at all. She would have seen me go all the way from soft to hard. I could tell where her focus was. I confirmed by stealing a quick glance at her out of the corner of my vision. She was looking under my blanket and I even thought I saw movement under her blanket, right between her legs. Was she touching herself?

I couldn’t be sure, but the thought of it turned me on even more than I thought was possible. Maybe I could touch myself a little bit too.

I let my hand slowly and quietly find its way to my cock. I wrapped my fingers around it and slyly started to stroke it, all under the watchful eye of my SIL. It felt fucking amazing.

I couldn’t help myself. After around 30 seconds or so, I finally looked at her and she was looking at me too. My head turned slowly and we made eye contact. Both our faces were lost in pleasure. She was definitely touching herself too. We stared at each other for what was the longest ten seconds of my life.

Not wanting to get caught, I broke the eye contact and turned back to the movie, but kept stroking myself. For maybe another 15 minutes, we both masturbated silently on the couch next to each other. It only stopped when my wife started moving around and snapped us both back to reality.

We ended up watching the rest of the movie without any risky antics but I know we were both thinking about it the entire time. After the movie ended, my SIL went home and my wife and I got into bed. I fucked the hell out of my wife from all the pent up horniness. Hopefully my SIL gave herself some much needed relief too as soon as she got home.
