Bab 178: Sudden Orgasm (R-18)

"Have you finished your training, Erwin?" Valara asked, extending her greetings to both of them.

Erwin nodded, a hint of pride evident in his response. "Yes, the professor taught me about the Arcane field today."

Valara acknowledged his progress with a nod, then turned her attention towards Adelaide, unaware of Erwin's subtle assistance in stretching her anus. "Professor, are you available after this? I have a spell I've been struggling with. Could you lend me a hand?"

Adelaide nodded, her face betraying a mischievous smile. "Of course, Valara. I'd be happy to help."

As they engaged in conversation, Erwin discreetly continued to support Adelaide's endeavor, his hand gently squeezing her buttock, providing the subtle encouragement she needed. Valara, focused on her own spellcasting issue, remained oblivious to the hidden dynamics at play.
