My step-mom and I have always been close, some have said a little too close, but she's never been inappropriate. Well that all changed when I came home early from college today cuz I had poison ivy so bad I couldn’t focus. I got some medicated cream, and she wanted to put it on for me cuz my hands were all bandaged up. Seems weird, but she insisted. Well, not only was the rash on my hands, but my chest and thighs and... my junk. She really pressed me to be a helpful step-mom, so I let her put the lotion on my junk. She was even so thoughtful to strip down naked so I wouldnt be so uncomfortable with her seeing me nude. Anyway... about 10 seconds after my already hard cock came out of my pants, it was in her mouth. Then she took me over to the couch and fucked me good. I came a fat load on my step-mom's ass... I'm so ashamed...
