Mastermind: Genderbent Villainess

"AAAAAAH~!" Tanya's body collapsed on top of Penelope, a thick mana-imbued substance leaking from her. This was like nothing she had ever felt before.

If she had not already lost her pride as a man, she had now. Her behind had been utterly destroyed, she wasn't even sure if she could sit or sleep on her back tonight. 

"Ah… Tanya, you were so tight…" Rose was sweating all over, clearly the most fatigued she had ever been. She did not know exactly why she had gone so hard just moments ago, but she knew that it was one of the best feelings she had ever had in her life. When she looked forward, she only saw Tanya desperately trying to pull herself off of Penelope to breath.

"Of course I am! I HAVE NEVER PUT ANYTHING IN THERE!" Tanya was furious. 

'You could have at least warned me!'

The feeling was unbearable. 

"Geez… Tanya, you weren't going any gentler on me… There's blood all over the sheets." Penelope sighed, hugging Tanya passionately like a doll.

"Humph! Could you at least apply some ointment over there… it hurts." Tanya was biting her lip intensely, nearly causing blood to come out. Out of all the things she had done in this world, that would have to be the most painful.

"Fine fine…" Rose warmly smiled as she retrieved a small vial of medicinal ointment from her handbag. At times like this, Rose was always ready. While not effective against stab wounds, she wa fairly confident that this much would be able to help Tanya with her pain.

She slowly spread Tanya's cheeks from behind, but she did not end up applying ointment.

1 hour later:

"No one is allowed to talk about today." Tanya ordered.

"I cannot believe the damage was so terrible that I had to wake up Yuri for a healing spell." Tanya was really irritated. She just wanted to rest now, she already had enough bed activity for weeks.

"Tanya, are you alright?" Penelope asked.

"Of course not. You heard me crying for the last hour didn't you? I really cannot believe I let you hear me act so weakly… this is an issue indeed… so keep quiet about this please."

"Your crying was so cute though…" Rose whispered into Tanya's ear.

"What happened to proper etiquette and waiting for marriage?" Tanya still could not believe Rose had actually done it with her. It was still far too unbelievable for such a prudish woman to be so savage in bed. She did not even slow down! 

'You just kept on going and going… thrusting and thrusting like you don't know how to use that thing… sometimes blind thrusts do not make it all so enjoyable.'

Tanya concluded finally, 'Rose needs to practice before we ever do this again.'

It was absurd and did not make good use of the tool she had possessed. If anything, Tanya had to be ruthless and tell Rose exactly how she felt. Only by doing this can she not suffer in bed again.

"Rosy, you are sh*t at sex." Tanya projected her voice directly back at Rose, her face deadpan.

"!!!" Rose jumped back out of reaction, expecting Tanya to flirt back. Instead, all she received was a terribly harsh criticism from her fiancé.

"When you use a dildo, you don't blindly thrust like a berzerk animal. That is not how you pleasure your partner; that is how you KILL your partner." 

The room became silent just like that.

"..." Rose looked down at her feet, unable to respond. On one hand, she was proud that she finally lost her virginity; on the other, she was disappointed in herself for not being able to satisfy Tanya properly.

"Stop being a hypocrite, you did the exact same thing to me~" Penelope giggled.

"But I could tell you loved it." Tanya placed her palm over her face. She had centuries of experience in the matters of the bedroom. She knew exactly when the time to stop was. That is the experience afforded to a veteran.

"You have me there…" Penelope had no excuses this time. She could only look at Tanya's annoyed face.

"Thank goodness The other girls are not here. It would be incredibly embarrassing if they had watched the entire time. How would I be able to hold my head up high if they all know? Well bygones be bygones. 

CHOP

Before Rose could react, her device was cut in half by Tanya's hand. 

"Now give me a backrub, that does not mean to do 'that' again." Tanya ordered, lying on her belly.

"Fine…" Rose sighed. Her pride had vanished into thin air. Out of all the things she had to be terrible at, it had to be the bedroom. 

Meanwhile, in a closet, five girls were huddled up together, peering through the slits.

"Wow… that was intense… more intense than a duel with Tanya." Erina whispered with a face full of fear. She had never seen something so monstrous happen in her entire life. It was like a horror film.

"That is nothing. Tanya is correct in saying that Rosellia is terrible in the bedroom. If I was in Rosellia's position, I would have used the proper protocols for anal penetration. First you need to…"

"Shush." Yuri placed her hand over Yuna's mouth. Although she wanted to learn about lewd things so she could use them on Tanya, she thought doing it using the butt would be dirty. She wanted to be clean when she made love with Tanya.

"I must say, I think I would have fainted if someone did that to me… I think only Tanya has such a strong will." Diana sighed. She still could only look at Tanya from a distance. She was quickly feeling the anxiety of missing out.

And then, the door creaked open.
