I live with my older brother, because saving on the rent helps, but there's another reason, a hidden reason. I fuck him and we have a relationship! We find it sexy, the fact that we are so closely related. So I came up with the idea to lure our younger brother into this, like a good-kept family secret! My older brother not only allowed it, but encouraged me and expressed his desire to do a threesome, as a fantasy. I already knew that my younger brother is not prudish at all, and he seemed attracted to me, so I'm gonna break these taboo boundaries and try to have sex with him! I went to his house, he was home alone (perfect!) and I began to tell him a story, a real one: that I had been fucking our older brother and how sexy I find it, even if other people may find it gross and weird, I find it sexy and unique! He got hard listening to the story, and to be honest, that's the exact reaction I expected, so I touched him and rubbed his cock! I didn't want to scare him or something, that would ruin our moment so I took it easy. Of course, I dressed up for this event, doing my hair and choosing slutty clothes that highlight my Big Boobies and Perky Ass. When I felt that he was comfortable and relaxed I considered it's time for a BlowJob... a special one! Laying on the bed next to him it was easy for me to suck it artistically, to feel His cock with my soft lips. He started pushing his cock into my mouth, I like it so much to be mouth-fucked! Then I keeled in front of him and continued the BlowJob, this time with a lot of DeepThroat. His cock is considerably bigger than our older brother's! By now I switched to Titty-Fucking watching his ecstatic expression as I pushed my Big Titties down on his throbbing cock! He grew hornier and so did I. I put it out of my mouth and simply mounted that cock, riding it and bouncing my boobs in his face. We both were moaning, I just needed cock, I'm a little nymphomaniac. We changed the position, I layed on my back and he fucked my wet insatiable cunt until I came, twice! It was my turn to make him cum. I gave him a good TitJob, rubbing that throbbing cock between my tits, hands-free, until it practically exploded with cum, sploshing it everywhere! That's a nice first fuck, brother!
