This is what happened the next day after Mom caught me wearing her clothes, feeling her up and stroking off, of course.
I spent a sleepless night worried about what my lovely Mom would do to me the next day. Fortunately I was still wearing her lingerie so I spent my time admiring myself in the mirror and stroking my hard cock until I came again and made another big mess.
The next morning Mom came to my room and told me she was going to punish me. She took me to her bedroom and made me put on a girdle that was quite tight, but open at the bottom. I was then told to put my stomach on her lap, which I did and Mom began to spank me with her pretty hand. She began to hit me, but I could hardly feel it through the girdle covering my ass. Mom spanked me progressively harder, and I begged her to stop and I could sometimes feel her bouncing breasts brush my back and my cock grew hard. I couldn't resist running my hand across her shapely ass which caused her to hit me harder. My cock poked through the opening at the bottom of the girdle and the tip of it was rubbing her leg and leaking precum. Mom's leg began to squeeze against my cock and my hand was having a great time feeling her ass. I could smell Mom's perfume and her womanly scent as I humped her leg and I saw stars and shuddered as I shot a load of cum all over her legs while she pressed her tits in to my back. Meanwhile, Mom was making moaning sounds and wetness ran down her legs as her ass shook. After a minute or two Mom said for me to get dressed and meet her down stairs.
