Important note. I already said this before, but I will repeat. Here we are using real people to fantasize, but I really hope you guys don't find this offensive. I personally enjoy Blackpink's art and I adore them for their hard work and passion.

The story continues now. This story is mostly about penetration, humiliation and pet play. If you are not into, just skip it.

"What do you mean you are not in a mood? But I've already prepared him so nicely. He is on his four legs, in a doggy position, waiting for you to take his behind virginity. Yeah, I took his front virginity, now it's your time to take his behind virginity. Listen, if you are angry, you can just destroy his ass and blow off some steam. Don't worry, he is super obedient. Just come." Rose put her phone on her bed, got up, and approached me. I was in a very humiliating pose. My legs were tied to my calf, so I was "standing" on my knees. She also put some doggy palm gloves and cuffed my hands right with that. On my head she put doggy ears and she also made me wear a pajama that looked like a dog costume. My ass part was open, but inside my hole there was a toy dog tail. Rose grabbed my hair and I thought she will say something aggressive, but she spoke surprisingly gentle.   


"Now Lisa is coming and she is upset because she had a conflict with our manager. This idiot wanted to ban Lisa from social media because he saw an article that this is bad for mental health. So, let's review what we have learned," she ordered and watched with a demanding face.   


"Woof, woof" I made barking sounds and rotated around. It was very painful because my lower part of body was holding on my knees. But I really wanted to make girls happy, so I wasn't complaining.   
"Hahaha, nice. But you forgot something," she giggled. I took my tongue out and started to make sounds of a hungry dog. She smiled and said, "Nice. I am really proud of you. If you make my Lisa happy today, I may fell in love with you." 

This idea made my heartbeat faster. I thought that this is my chance. It appeared that we are both very polygamic and we didn't feel any shame about this. Finally, Lisa entered the room. She looked very annoyed, but when she saw me, it gave her a gorgeous smile. She was wearing regular, blue sportswear. It was very tight, especially her shorts. Maybe she came from a swimming, I wasn't sure. She approached me and I did as Rose explained me. I quickly ran to her feet on my fourth legs and took my tongue out and made some dog noises. As Rose told me, Lisa was crazy about pet play. She held her cheeks and said, "I can't believe you found such a treasure. I hope I can find one too and share with you too. This boy is unbelievable." Rose told me that I must rotate and move my tail every time I get a compliment. I did it, and this made Lisa to widely open her mouth, "I am taking this doggy right now!" Rose laughed and handed her a pink dildo that she was holding in her hands when Lisa entered. After Lisa took it, she spitted on it and held it near my mouth. I knew what this means because Rose taught me well. I started to lick it all and while I was doing this, Lisa just put it deep in my throat. I stared to make noises of a struggling dog as Rose taught me. They both laughed very loudly. "Okay doggy, now climb on the bed and try to spread your legs as much as possible." I turned back and crawled to the bed, but it was very hard to climb up because the bed was high and I was tied uncomfortably. After I started to struggle, I made dog struggling noises again, and girls laughed, this time very loudly. They didn't expect this to happen. Rose came near and said in a nice tone, "Aww, let me help you to climb," and she started to kick to my ass with her legs mercilessly. Lisa joined immediately. They keep beating my ass, as if trying to kick me onto the bed like a football. Lisa bullied me, "Come on, we will beat you to death if you don't climb that bed, haha," and she started to hit even harder. I started to make normal suffering voices combined with dog struggling voices because it was really painful and hard. Finally, I made a little jump and ended on the bed. I was breathing very quickly, as if I ran 1000 kilometers. Rose slapped my ass and mocked me, "Look at that red ass. It really needed some destruction, haha." Lisa came near and she also slapped my ass very hard, "I told you to spread your legs." I quickly did it and she didn't gave me any seconds to prepare. She took out my tail and immediately put that dildo inside me. I opened my mouth to yell in agony, but Rose was prepared. She was holding a pink thong, and she immediately gagged me with that, so my yelling became a silent moan. "If this falls, I will fuck your throat with bigger dildo, understood?" she asked. I nodded and started to moan again and again because Lisa already started to fuck my ass. She grabbed my hips and started to go quicker. I was in agony. It was my first penetration, and I got no preparation at all. She just grabbed me and started to fuck. The pain was so intense that I seriously wanted to cry, so they feel sad for me and stop it, but then I remembered that I cannot disappoint my Rose, and this thought gave me some strength to persevere. Lisa went super quick, but the pain started to decrease because my asshole was extending and getting used to it. Rose lied on her bed, put her foot on my face and started to push my body back, so the penetration would be even more painful. Lisa was pushing me forward, Rose was pushing back. "Yes, yes, oh yes, you like that, I can see it, oh yes," kept saying Lisa. After around 20 minutes of ass fucking, she got tired, and took out her dildo. She lied on the bed and opened her pussy. Rose attacked the dildo on my face, and made me go inside Lisa. Rose sat on my back and started to dictate the tempo. Around 45 minutes I was a human vibrator. Rose was making me to go fast and slow, as if I was a sex gadget. Finally, Lisa had her erection, and Rose took me out of her. She took the dildo off, and whispered in my ear, "You made me proud." I thought I was the happiest man ever. Not only because Rose was satisfied, but also because it was really painful to do this all for them. Lisa sat on the edge of the bed, took off the thong from my mouth, and Rose put her foot on my neck. I knew that this meant to make me kneel. I bent down and started to kiss Lisa's feet. She said with a very satisfied voice, "This is why we always wanted our sub to be an athlete. No one else could handle what you handled today, Good job." She grabbed from my hair, pulled me up and started to kiss very aggressively. She put her tongue inside my mouth and started to literally fuck my mouth with that. It was a pure pleasure. While Lisa was having her orgasms, Rose already released me from ropes, so I was just on my knees and being tongue fucked by this goddess. Then she released my mouth and said, "Seriously, guys, thank you so much for this. I was so angry, so annoyed, but you made my day happy. And you, you are a treasure, but you still don't deserve my Rose. So keep being a good boy." I bent my hands, took my tongue out and barked. She giggled, took her clothes and went to the shower. Rose came in front of me and suggested, "Now she is taking a bath. Take your underwear on, go there and start washing her body. I will go downstairs to ask them to prepare some food. After the shower, give her some massage here, on my bed. She will be amazed." "You are right," I answered, kissed her both knees and handed to the bathroom.
