Caught! My sisters boyfriend knows my secret!

Suddenly my sisters boyfriend stands in front of me and tells me that he knows my dirty secret. I guessed what he meant but hoped he meant something else... hoped in vain. So that he doesnt tell on me, he makes me an immoral offer. He wants me to suck his hard cock. Admittedly, this hard cock made me so hot that I just wanted to be fucked! He fucks me on the dining table where were having a family dinner that same evening. And feels my mouth with his cum! Im such a slut! But I cant help it...
