[FF] My boyfriend’s mom caught me wearing a huge butt plug… then made me put it in her ass

I still can’t believe this happened and I need to tell someone before I lose my mind.
My boyfriend and I have been together almost two years. His parents are sweet, traditional people. The last thing anyone would expect is their son’s girlfriend showing up for family dinner with a thick, heavy butt plug stretching her open. I’ve been into wearing them for a while though. The bigger the better. That constant full feeling just makes me feel so filthy.
Yesterday I put in my largest one before heading over. It’s thick, flared, and once it’s in I can feel it with every step. I was already wet just thinking about sitting through dinner with his parents while it was buried inside me.
Dinner went fine. I was careful how I sat. Afterward I got up to use the bathroom. When I opened the door, his mom was standing right there in the hallway. She looked me up and down, then her eyes locked on the obvious outline through my leggings.
She went quiet, then said in a low voice, “You’re wearing something, aren’t you?”
I tried to deny it. She wasn’t having it. She grabbed my wrist, pulled me back into the bathroom, locked the door, and told me to turn around and pull my leggings down.
I was shaking. Completely red. But I did it.
She stared at the base of the plug for a moment, then reached down and took hold of it. No warning. She worked it out of me slow and firm while I stood bent over the sink with my pants around my thighs, biting my lip so I wouldn’t make a sound. When it finally popped free she held it up, looking at the size of it.
I thought that was the end of it. I was wrong.
She set the plug on the counter, looked me dead in the eyes, and said, “Now you’re going to put it in me.”
I froze. She didn’t repeat herself. Just turned around, pulled her own pants and underwear down, and bent over the sink the same way I had been. Then she looked back at me over her shoulder and waited.
My hands were shaking so hard I almost dropped it. I had to use the lube I keep in my bag. She didn’t say a word while I pressed the thick head against her and slowly worked it inside. I could feel how tight she was. Every inch took effort. When the widest part finally pushed past and the base seated against her, she let out this quiet, shaky breath.
She stood up, fixed her clothes, and looked at me again. “Clean yourself up. And don’t ever come into this house wearing one of those again… unless I tell you to.”
Then she unlocked the door and walked out like nothing happened.
My boyfriend still has no idea. I got home later, washed everything… and I still can’t stop replaying the moment she made me put my own plug inside her.
Has anyone else had a partner’s parent turn something like this around on them? What the fuck do I do if she ever brings it up again?
Be honest… am I disgusting or is this kind of hot?
