Kara’s POV

I groaned as I slowly opened my eyes. I felt the horrible effect of Kryptonite. I whimpered and tried to get my head on straight. I frowned and slowly lifted my head. There in front of me stood a smiling Lillian Luthor. “Well hello darling I see you are awake,” Lillian’s smile never leaving her face, “what do you want now? Where am I?” Lillian walked up to me, “it’s simple Supergirl.” My head was still slightly fuzzy but I knew this wasn’t a Lex thing it was just Lillian.

“I’ve decided that the best way to get rid of you is to trap you. Have you as my pet,” Lillian cupped my face. I quickly flinched, “I will not be a pet to you Lillian. Alex and Lena will find me,” I spat. Lillian chuckled, “oh baby by the time they find us you will already be my loyal pet.” I tried to get free but it was too much at the moment. Lillian walked away and came back seconds later with a collar, “now this can either be your greatest gift or your downfall.”

I stared at the collar in Lillian’s hands. It’s blue and red but something was off about it. Lillian fixed it to my neck and pulled me closer by the collar. “Yes this will do nicely,” Lillian purred. Suddenly I dropped to the floor. I tired to make a run for it but then a sharp electrocuting shock ripped it’s was threw my body. I fell to the ground trying to get the collar off. “Now let me tell you the thing about that collar Supergirl. You will never get it off. I have a remote that turns your powers on or off. And the fun feature is this button that electrocutes you whenever I want to.”

I whimpered and slow made my way to my knees, “they will find me and you will be put to prison.” Lillian sighed, “we are in a panic room in a safe house that no one knows about. We are under so much lean lined walls not even your cousin will be able to find us.” I shivered at the thought. “Why are you doing this to me?” I whispered and Lillian stepped in front of me and played with my blonde hair, “because I hate you Kara Danvers. You have caused nothing but trouble with my family. So I’m taking you away so you can’t cause more problems.”

“Now I think you need to be in far more appropriate clothing,” Lillian picked me up by the collar, “follow Pet.” I looked down. The only way out of this is to play along Lena will find me. I followed after the older woman. “Good pet,” Lillian praised and I looked to the floor. As we made our way to a bathroom I frowned then when I looked down I see that I am quite dirty. What the heck was I doing before I got kidnapped?

“Strip,” Lillian commanded and I flushed red, “no.” Lillian raised an eyebrow. I couldn’t help the shiver that went down my spine. I forget sometimes where Lena learnt her mannerisms. “Strip Kara or I will strip you myself,” Lillian threatened and I looked down again. I slowly peeled off my Super suit until I was left in my sports bra and panties. “Good girl. The rest now,” Lillian commanded and I closed my eyes taking off my sports bra and panties.

Lillian turned on the shower, “get in.” I nod and stepped into the thankfully heated shower. “Wash yourself. I like my Pets nice and clean,” Lillian taunted and I tried everything to block out her words. Once all the dirt was washed off me Lillian handed me a bottle, “hair to Pet.” I went under the water and started washing my hair taking as long as possible. Every second is a second closer to Lena finding me.

When I completed washing my hair I looked up at Lillian who smirked, “are you all done Pet?” I nod, “yes.” Lillian stood up straight, “yes what pet.” I frowned, “yes I am?” Lillian grabbed my jaw tightly, “you will answer me and address me by my title.” I whimpered as Lillian squeezed tighter, “yes ma’am.” Lillian’s hand tightened, “yes mistress.” I whimpered louder, “yes mistress I’m sorry mistress.”

Lillian let go of my chin, “Lena not teaching you manners pet.” I let a few tears fall, “Lena likes to be called Daddy Mistress.” Lillian smirked, “good then you are to behave for me just like you did for my daughter. DID Pet it is past tense. From now on you only obey me.” I looked down, “yes mistress.” Lillian pulled me out of the shower by my collar, “good now let’s go it’s time for training.” I shivered and followed after the older Luthor.

When we got to a bedroom Lillian crawled onto the bed and laid in the middle, “tell you what Supergirl if you can guess the size of the strap I am currently wearing I won’t force it down your throat.” My eyes snapped up and I felt fear rush over me. I was shaking and Lillian looked pleased with my body language. “8?” I whispered. 8 was one of Lena’s biggest. Lillian chuckled and full blow fear rolled through my body. I’ve barely taken anything over 8. “Tell you what Pet I’ll give you one more guess,” Lillian smirked. “10?” I whispered again and Lillian chuckled again, “come over here pet it is time for training.”

I walked over to the bed and Lillian pulled up her dress. I saw the strap outline in her boxers and I know this is not going to be fun for me. I was right. As soon as Lillian took off her boxers the largest cock I have ever seen is revealed. I whimpered and Lillian smirked, “Lena only played with 8?” I nod. “Well Pet you better get used to this because the smallest I own is 11 but you caught me on a good day. Now this 13 inch monster to going to destroy your insides.”

I was shaking. Please Lena now I need rescuing now. Please. Lillian chuckled, “come over here Pet.” I made my way over to her and she pulled me so my head is in between her legs. “You are going to give me a blowjob Pet or I will shock you then fuck your throat until I’m satisfied,” Lillian growled. “I’ll give you a blowjob Mistress,” I whispered, and Lillian smirked, “go on then pet.”

I grabbed the 13 inch rubber cock and took the head into my mouth. It was thick too. It hurt to stretch my mouth out but I still did it. As I was 5 inches down I needed a break but Lillian’s hand was stopping me from moving back. “Breathe through your nose,” Lillian growled. As I was relaxing my throat Lillian grabbed the back of my head and started pushing down until I was choking on her cock. “Yes fucking choke on it whore,” Lillian moaned.

As Lillian pushed all the way down my throat I felt sick. It was so big. I tried the humming trick Lena taught me and it worked. But Lillian didn’t give me time before she was fucking my face. I was gripping her thighs tightly. “Fuck it’s been too long since I’ve had a toy to fuck,” Lillian growled fucking my face harder. I whimpered and Lillian just kept going. The rubber cock feeling heavy in my mouth. I’m sure it’s visible with how far down my throat she is.

Lillian with her free hand reached under my body and gripped my tit, “I see why Lena has taken a shine to you. She always was a sucker for a nice pair of tits.” I looked up to see Lillian’s face shift. All of a sudden Lillian pulled out of my mouth and flipped me over. I yelped and she climbed onto my chest placing her strap in between my tits. I looked up at her dark eyes, “you are mine to play with aren’t you Pet.”

Lillian pressed my tits together over her cock as she slowly started to thrust it in between them. “I love Lena,” I spat but that was the wrong thing to say. The feeling of electricity coursing through my body made me cry out. When the feeling stopped I looked up at Lillian as tears rolled down my cheeks. “Who do you belong to Pet,” Lillian moved off my chest and in between my legs. “You mistress,” I answered and Lillian smirked, “good girl.”

Lillian spread my legs and rubbed a hand on my pussy, “I am going to enjoy fucking your disobedience out of you.” I whimpered and Lillian pressed her cock head against my entrance. “Please Mistress it’s too much,” I whimpered and Lillian smiled cruelly, “oh Pet then it wouldn’t be fun.” Lillian forced her strap inside me. A scream left my mouth at the burning feeling. Lillian smirked and as her cock pressed inside me about half way she started the hammering pace.

I was sobbing at the pain until it started to feel good then I cried more. “What’s wrong whore? Am I ruining you for your girlfriend?” Lillian bit down on my shoulder until it’s bleeding. Her cock was hitting my cervix with each thrust and it was a mix of pain and pleasure. “Mistress,” I stuttered and Lillian grabbed my neck and tightened her hold on it. I struggled to breathe and Lillian fucked me harder. As I saw spots in my vision she pulled her hand back.

I panted but soon I screamed as her cock pushed past my cervix into my womb. I couldn’t stop myself from cumming at the rush of pleasure and pain. Lillian was close and moaning, “The mighty Supergirl cumming on Lillian Luthor’s cock if the world could see you now.” I let a few tears track down my face. When Lillian’s thrust stuttered I know she has cum. I whimpered and Lillian grabbed my face, “you will always be my pet now.”
