So my step-Son and I went to a Halloween Party together. The party was huge and I had to go to the bathroom.  I asked my step-Son to go with me so we did not get separated. I noticed that he was watching me as I peed.  After I was done, I saw that he had a hard on.  I could not let him go back to the party with a boner so I took care of it for me.  I blew him until he shoot off all over the floor and my tits.
