For Sarah to be wearing Lidia's poopy diaper.

"You know, Sarah, you've changed enough it my dirty diapers this last few months, I know you must really love them," Lidia said as she continued to pin me to the couch by pressing her shitty diaper into my face. "You seem to love my dirty diapers enough, maybe I should let you wear this one? I bet you'd like that, right little Sarah?"

I tried to protest, but I couldn't get words out given the smell enveloping my face. Everytime I opened my mouth, I couldn't do anything but gag.

"I wish that Sarah was wearing my messy diaper instead of me," Lidia wished.

Suddenly, I didn't feel the plastic cover of the diaper pressed against my face. Instead, I was suddenly nose deep in Lidia's admittedly beautifully round and toned ass. At the same time, I felt my legs spread apart and my backside lift up as something soft and bulky suddenly replaced the now too-large lingerie that was previously covering my ass. I could also distinctly feel the lumpy, sticky sensation of Lidia's shit pressed up against my ass cheeks and pussy. I couldn't believe I was actually wearing Lidia's messy diaper.

"Ah! That's much better, don't you think Sarah?" Lidia said, looking over her shoulder to inspect her handy work. She laughed at the sight. "Oh yes, you look like you are right back where you belong , little one. Sitting on the couch like a scared little toddler in a poopy diaper. Oh, don't pout, I know you love it," Lidia continued. "Actually, why don't you show me how much you love it. Why don't you like your new Mommy's pussy to show her how much you LOVE sitting in your new shitty pampers!" Lidia ordered.

I pulled back from Lidia's exposed ass and pussy in disgust as Lidia pushed it closer to me. At my movement, Lidia grabbed the pendant in her hand and showed it to me.

"Ah, ah, ah, baby girl. You do what Mommy says, or this can get worse for you. Do I need to show you what I can do? I have some wonderful punishment ideas," Lidia said menacingly.

I swallowed nervously, looking at the pendant in my former captives hand in fear. I knew precisely what she could do with that.

"Please, don't! I'll be a good girl, I promise!" I said rapidly, not wanting to give Lidia any time to believe I wasn't going to comply.

"That's what I thought, now show Mommy how much you appreciate her my precious little poopy princess," Lidia commanded, watching her back further and shoving her clean shaven pussy into my face.

I shuddered at Lidia's new nickname for me, but knew what I had to do to survive this situation with as much dignity as possible. I opened my mouth and leaned forward on the couch, grimacing at the feeling of Lidia's shit moving around in my pants. I opened my mouth, stuck out my tongue, and began going to work on Lidia's vagina.

I began by slowly circling my tongue around Lidia's labia, feeling the folds of her soft pussy with my taste buds. Doing this, I felt her hard button of a clit, and redirected my attention, alternating between gently flicking it and pressing on it with my tongue. As I worked, I could here Lidia beginning to moan. Due to my machinations, she had been deprived orgasms other than those she has while humping her messy diapers for months. I could tell she was enjoying this.

"Good baby, just like that!" Lidia told me as she sat back harder on my face, nearly suffocating me as I start alternating between licking her clit and darting my tongue in and out of her slit. Despite my tongue getting sore from my efforts, my difficulty breathing, and the disgusting mixture of Lidia's pussy juices and my saliva dripping down my chin into my exposed breasts, I can feel myself beginning to get aroused by the situation. As I continue to pleasure my lifelong bully, I can't help but start to rock back and forth in my seat, humping the messy diaper I am wearing just like the naughty little diaper slut I turned Lidia into months ago.

As I continued to work my magic with my tongue, Lidia's arousal reaches it's peak. She suddenly shoves her groin into me with all of her might as she starts to scream. My tongue, is inside of her, feeling as her vagina throb as Lidia orgasms over and over again. I can't help myself. This is too hot. Despite my embarrassment, I reach my hand to the front of the shit filled diaper strapped to my waste and started rubbing my own vagina over the padding. The stimulation felt good. I started to moan myself, the vibration of which sent more shivers of pleasure pulsing through Lidia's body, causing her to cum again.

I started to rub myself harder, desperately trying to bring myself to orgasm before this was over. However, just as I was about to finish, Lidia quickly pulled herself away from my face, turned around, and looked at me with a mischievous grin on her face.

"Well, what do we have here? A naughty little baby trying to cum in her babysitter's messy nappy? What a disgusting little pervert you are! What am I going to do about this?"

I temporarily stopped rubbing the front of my diaper, petrified as Lidia reached for my magical amulet again, smiling darkly.
