By 6:00 PM, the sun was setting over Kyoto. Students were returning to the hotel, but the lead teacher, Rossweisse, was occupied in the bathroom. Behind the frosted glass, her silhouette moved up and down as she rode Ethan in the bathtub.
Ethan watched her silver hair sway, his hands gripping her heavy tits. He had marked her body well—red teeth marks and hickeys covered her neck, breasts, and thighs. After their first round on the bed, Rossweisse had woken up in the tub and immediately climbed back onto his cock, her eyes glazed with a mix of exhaustion and insatiable greed.
"I'm sorry, Rossweisse. I might have been a bit too rough for your first time," Ethan said.
"Don't apologize," she gasped, her pussy clamping down on him as she hit another peak. "I'm your Valkyrie now. Everything I am belongs to you."
Ethan stood up in the tub, lifting her so she was pinned against the wall. He hammered into her, her breasts bouncing wildly. Rossweisse screamed as she reached a massive, toe-curling climax, her juices spraying across Ethan's thighs.
After cleaning up, they returned to the bed. Rossweisse, ever the diligent learner, had practiced her "theory" well. She climbed onto him in the "cowgirl" position, her massive tits swinging as she bounced on his iron-hard cock.
"Oh! It's too deep! Ethan! You're hitting my womb!" she cried out as Ethan's eighteen-centimeter cock breached her cervix, stretching her internal walls. Her belly slightly bulged with the shape of his head.
"I'm going to fill you up, Rossweisse," Ethan growled. He gripped her hips and met her movements with violent upward thrusts. Rossweisse's internal muscles convulsed, and a fountain of nectar sprayed from her depths, soaking the bed.
Ethan couldn't hold back any longer. He flipped her over, pinning her legs to her shoulders, and delivered a final, frantic series of thrusts. He buried his cock to the hilt and unleashed a massive torrent of hot, thick cum directly into her womb.
"Ahhh! It's so hot! So much!" Rossweisse wailed, her body shaking as she absorbed his life essence.
Because of the Dual Cultivation, Rossweisse instantly broke through to the Satan Class. Her strength soared to the peak of the rank, though she would need more sessions to reach the God Class.
"You look beautiful, Rossweisse," Ethan said, looking at her slightly distended belly, filled with his seed.
"I have to go do room checks soon..." she whispered, blushing. "How can I walk like this?"
"Just use an illusion spell," Ethan chuckled. He reached into his storage space and pulled out a set of black lace lingerie. "But first, put this on under your clothes. I want to know you're wearing it while you talk to the students."
The silver-haired Valkyrie obeyed, pulling the sheer black fabric over her cream-covered thighs. Her large D-cup breasts were barely contained by the lace, her nipples peeking through the gaps. To anyone else, she was the cold, professional teacher. But only Ethan knew she was currently a dripping, cum-filled mess, ready for more the moment the door closed again.
