My brother fucked me (18f) blindfolded and tied up instead of my bf

My bf (18m) is really into bdsm and cnc. He was coming over so I wore a blindfold, pear in my mouth as a ball gag and my airpods to block sound and zip tied my arms to the bed frame and spread my legs with my phone on notes with the message "use as please" open on it. My brother (19m) was supposed to be out with friends but he came home early and my bf cancelled on me since his mom needed his help but because I was blindfolded I didn't know since my phone was on silent. My brother walked in my room asking if I wanted lunch since he was back but I couldn't hear him so he came in my room where I was naked and tied up with a phone that says "use as please". I was really wet so my brother just slipped it in me. I couldn't see, moan, hear so I was so overstimulated that I came pretty quick and soon after my brother cummed inside me. I had texted my bf not to cum inside since I didn't have more birth control. When my brother came inside me I spit out the pear and said "wtf (bf name) I told you not to cum inside me. My brother took off my blindfold and my airpods and said sorry he thought it was for him since he always looked at my body. I wanna be mad at him but I did basically tell me to use my body and his cock was really big and felt so good. I might do it again but I'm scared since its my brother.
