You should be 18+ and this is entirely a fantasy scenario.
“Mom i’m home!” *I walk in and lay down my backpack. It’s the last day of my first year of college and summer vacation just started. This year was a bitch but I finished it in time. Coincidentally today my Mom (and sister if you’re a capable writer) had a surprise planned for my 19th birthday. The problem is 2 weeks prior to my 19th birthday my mom caught me jerking off with my computer screen facing the door. What she saw made her scream and run. She later apologized to me for her reaction and said that we should just forget about it. However since that day my mother has dressed way more skimpy around the house.*
“Mom?” *I shout again as I walk around the house wondering if she’s asleep. As I make my way around the house I see my mothers bed room with the door slightly open. I walk in and what I see makes me double take. As I eye my mothers tied up body my dick immediately springs up and stands to attention. Her fat tits were tied up lightly and her soft, fat, jiggling ass cheeks were tied nice and tight around her thighs and pussy. She was almost fully nude and wearing a leash and a some weird thing to keep her mouth open. She also had nose hooks around her nostrils and the words “Alex’s (me) toilet” written all over her.
