"Yes... I am Nagato... yes... that's right..."

"Yes... I am Nagato... yes... that's right..."

Having contacted that classroom...

"..Yes..That's True..I am a love-conditioned sex girl...yes...I'll really swallow your semen.."

The voice of an aroused man...

"..Yes...Please wait a minute before stroking your d*ck..."

40 minutes later...The man who came to that classroom to do it was waiting to stroke his d*ck.

"..I am Nagato Yuki...You have waited...I am a love-conditioned sex girl...your semen..I will swallow it..."

The man who had exposed his d*ck abruptly pushed me down.

After that, I will take his d*ck... Original went something more like "Nuppu Nuppu his d*ck". I am not quite sure what this onomatopoeia is intended to suggest, but it definately has a sound to it that is either bouncy or slippery. It seems to be less common than other onomatopoeia I have seen.
