You do know how ecchi-comedy series goes, do you? They always get interrupted!

And also if sucking breasts was taken off the series, do you think sex scenes will be allowed?

Ofc, maybe in the future it may happen but the editors(?) will not allow it to be describe what is happening. It will most likely be a passing moment.
