I was expecting Christmas like a little one, because I thought it would be the perfect occasion to surprise my crush, or, better, my future boyfriend with sexy selfies under the Christmas tree! I decorated the house and bought a very showing outfit for this, I want to look perfect in pictures, most importantly to give him the impression that I am the Perfect Girl! While I was struggling to get nice shots, with the tree and decorations, which is pretty difficult by the way, my brother came in and surprised me while I had my Big Titties out for show! We are very open with each other, so I immediately shared my plan with him. I asked him to take some pictures, it's a lot easier when I only have to concentrate on my body and facial expression. I assumed sexy positions and just let him do the rest. He's got a hand for this, the pictures looked amazing and I was looking like a sexy Goddess. Nobody can say no to that, not even my brother! I'm not in love with my crush, I just want an open relationship with him, we both agreed to that, so I had an even naughtier idea: to take a selfie with a cock in my mouth, to tease him and maybe make him a bit jealous! The unique problem is I have no boyfriend right now and I really want a hard cock in my mouth to take that picture with, it will be a Christmas surprise, I can't wait until I find someone to fuck to send him that picture. But wait a minute, my brother is right here, and he's got some cock available! It shouldn't be to difficult to convince him... So I tried! Unzipped his red jeans and touched his cock. It was big, perfect for my purpose. He kept protesting about how we shouldn't do that because we are brother and sister and so on... I kept rubbing it until he started to feel aroused and got hard, that didn't took much! I put my mouth down there, around his hard cock and began sucking. It was weirdly hot, to suck off my own brother on Christmas Eve!... He was feeling the same, aroused and disgusted in the very same time. I DeepThroated it many times and every time he acted pleasantly surprised and shoved it deeper down my throat. I guess it's the first time someone DeepThroates that cock! Of course, I got horny in the meantime and wanted to fuck. It was to good and I think neither of us would've skipped this part. He fucked me doggy-style and it felt so good, almost unreal. His cock is thick and my pussy is very narrow, so it caused a lot of wetness and pleasure. We did it missionary for a short time, and I came so hard! It was the time to make him cum now, because he started to chicken out, saying he doesn't want to cum! I jerked his cock of over my boobs and the White Reward sploshed all over my Big Natural Boobies!
