I’ve (24F) never looked at my bf’s twin brother in this way before, but these last few days idk why I’m so soooo horny and it’s just messing with my head lol bringing my slut side out

It all started just a few weeks ago, we were all drinking together (bf, him and some of their friends) and he started to seem a bit more comfortable around me (laughing more at my jokes, smiling, touching my arm)… and I don’t know why the question “I wonder if his dick is just like my bf’s” popped up on my brain. I couldn’t think of anything else, and soon started into a spiral of naughty thoughts. This made me incredibly horny!

Fast forward to a week or two after this, we were again drinking with some friends and I noticed that he put his hands inside his boxers (right above his dick, in his pubic area) and my pussy started tingling so bad and I immediately could feel that I was wet hahaha I tried my best to not look at it since there was people around. A few minutes later he was talking and gesticulating and accidentally touched my left boob that bounced and he look at it. My nipples were hard and I was purposely not wearing a bra that night.. he got kinda awkward (he blushed and it was so cute) and I just smiled like nothing happened. I also caught him checking me out very quickly once when I was stretching a bit (from a long time sitting down). But that just triggered my brain even more! What if his dick is just as delicious as my bf’s? If it looks the same? Is it the same size or bigger? I wonder how would feel to be spit roasted or just shared, like I’m fucking two of my boyfriends… anyways don’t even need to say more, I couldn’t held myself anymore and went straight to the bathroom to get myself off and I came so hard! Came back dripping wet and with my pussy all creamy from cumming.
