So, long story short, this all started when I got bored and posted a photo of myself a while back. I found that my husbands brother had commented on it "looking good", despite the fact he was also in a relationship. I asked him about it via text, and he simply responded. "What? You looked great. I mean, I'm assuming D (that's my husband) doesn't know you posted it."
And he was right. D had no idea. We didn't mention anything about it for the next couple months, until December at a family birthday party. I was sitting on the toilet, getting some peace and quiet for 10 minutes, when I received a discreet picture from none other than D’s brother. It was a photo of him pulling his pants to the side, showing off his shaft and balls. I was shocked to say the least, but the wine id had that night led to me making a bad descision. I pointed my phone between my legs and sent him a picture of my vagina in return. Not long after there was a knock on the bathroom door. I got up and opened it, but it was him. He pushed me back into the room and just started kissing me all over. I kissed back, obviously, before he pushed me back down onto the toilet. He explained in a very hushed tone how we couldn't do anything too extreme here, otherwise people would hear us. He then started standing in front of me and stroking. It took a while, but he came all over my legs. Luckily my jeans covered it when I pulled them back up and returned to the party. A few days later, D was at work and I had a day off. Coincidentally, so did his brother, when he turned up at my place. The second I opened the door he was all over me, and a few minutes later we were both naked in bed, declaring our everlasting love for each other as he fucked the shit out of me. He came inside me and said we could just use the pill later. That was the best sex of my life. We've gotten together multiple times since then, and we're genuinely in love with each other. Call me a slut, but that man is my reason for living <3
