Kai indeed hadn't expected Watanabe to act like Nezuko and Yui as she was too mature for that.
She was standing in front of him completely naked and didn't look one bit flustered. Kai was proud of her behavior though it was just the start.
"Hmm, I wonder how long can you stand still for." He muttered as his hands cupped the underside of her soft breasts.
He pressed the two of them against each other while groping the soft flesh. Watanabe was no longer confident about standing still as she sat down on the bed with her cheeks slightly flushed.
Kai noticed it as he took his tongue out and licked her right nipple. His tongue circled around her areola while his other hand was fondling her left breast.
Watanabe had her eyes close and her mouth slightly open due to the moans she was releasing. She lost herself to Kai's touch as he suddenly pushed her down.
