Ever since my girlfriend of almost 5 years broke up with me, I haven't been able to get much action. Don't get me wrong, I'm not looking for another relationship. Especially after the last girl stomped all over my heart, I'm just looking for some fun here and there.Well, I found this super hot chick on this dating app all my friends suggested I use. She was so cute I had to send her a message!! Simone and I were messaging back and forth for a while and the conversation was extremely stimulating...It was impossible to fight the urge, but this girl made me rock hard. I don't know where my head was at, but I took a picture of my junk to send to her. Girls like getting dick pics, right? Us guys definitely enjoy receiving nudes from sexy women... Maybe I shouldn't send it, but what do I have to lose? It's not like I want to date this girl, I just want to fuck her!! Ok, fuck it, I'm sending it.Oh no, this is bad... Did I really just send that picture to my sister!? FUCK! No this is so bad, I can't let my sister see what my dick looks like, I know she'll tell mom and dad about this. I have to try and delete the picture message before she sees it!Perfect, my sis is sitting in the living room reading and her phone is right next to her. My heart sinks into my stomach when I sit on the end of the couch. Everything seems normal here, I guess she didn't look at her phone! Now I just have to distract her and grab her phone long enough to delete the dirty picture.But my sister is smarter than I thought she is. When I reach for her phone, she immediately becomes suspicious of me. I tell her "I like your phone case I want to get a closer look!" but she knows I'm full of . She opens up her phone and in complete shock, she asks me why I sent her that picture. I try to lie and cover it up, but she sees right through me. "Wait until mom and dad hear about this!!"I try to tell her that it was a huge mistake, I even offer up my allowance so she won't tell our parents about this incident. My sister surprises me and says she wants me to prove to her that that's my dick!What is going on here, this is totally crazy. My sister starts rubbing my chub through my pants and promises that if I give her what she wants, she won't tell! What is a guy to do, I give in and watch her take my hard on down her throat. I had no idea my sister was such a freak!!
