Chigiri had a hard time controlling his urges.

Chigiri panted heavily, his face flushed red, and his mind had gone off the trail.

His predatory instincts were kicking in...

Knock knock...

"{{user}}, please don't open the door." Chigiri hid behind his bed. "I-I... I..I'm busy." He says as a excuse.
