I think you guys had a girl playfully riding on her lap.

At that time, it is clear that the girl is probably in a position where she will not resist anything, even if she is touched in various places.

If you play around with it and tickle it directly, it's just a pun for the girl, so I think it's okay to put your hand in there.

Somehow calm down ...hey! !! wait a minute
