When I was a teen about 17 my stepdad caught me jerking off to a video I had taken with a hidden phone of my mom showering and masturbating. I was turned on by seeing my mom naked not just because she is sexy but the whole forbidden taboo of it all.

My stepdad wasn't mad, he thought it was kind of funny and totally condoned it. He asked if I'd like to jerk off to her in person. Basically she liked being tied up, blindfolded, gagged etc. and his plan was to have me sneak in when she was like this.

He texted me one night that he had her tied up and blindfolded and that she agreed to be fucked by his coworker in this state. I snuck in and played with her big tits and hairy pussy until I got hard and slid my dick in her. It was so fucking hot I can't even describe. I fucked her hard and even fingered her ass. The sound of her moaning to my dick was incredible. When I was close I pulled down the cloth in her mouth and came in her throat, which she happily swallowed. To this day she has no idea she was fucked by her own son and swallowed his cum.
