I find my brother’s nude photos on his ipad after I’m innocently looking up info for a school project. He walks in on me masturbating to them and is mad at first but then we have a tickle fight to make up. I notice his cock is growing while he’s tickling me in my underwear and no bra and he asis me to undress. I’m embarrassed at first so I have him help me. I then slowly lower my sweet pussy onto my brother’s cock because I know that’s what he wants, and I continue riding him and have dirty brother\sister talk. I decide to surprise him by inserting a butt plug and he double penetrates me, and before long he has me insert a dildo into my butt so he can feel it while I’m riding him. I tell him to cum inside me and I know I’ve been a good little sister.
