More effort is needed

"Good start", Rhea says. "For bad language, however, especially when talking about a teacher, a girl should expect a significantly harder spanking. If you want to stick to a small number of spanks, you should use a moderate implement at least and preferably a heavier one, such as this paddle here...", Rhea indicates a suitable one, "... ten to twenty with this should work, ideally towards the higher end. I would not recommend hand at all for such an offence, it really should only be reserved for small accidents and maybe a few slaps while you are lecturing, but if you want to stick to a lighter implement, you should look at a hundred spanks at least... And easily more. Also... it would usually be a good idea to punish the girl's mouth for swearing, for example with mouth soaping or a gag or even oral sex", she concludes, hoping the last suggestion will not make the young man faint on the spot.

It does not. Daniel nods, trying (and largely failing) to look both at the face of the older cousin and the bare bottom of the younger one as he listens. "Umm... Should I do a proper spanking for swearing now?", he asks. "Or just let this one go, do the mouth punishment and try better the next time?" Rhea considers this for a moment, although she thinks Neha might have a clear preference on this occasion. On one hand, practice is about doing it, not listening to how it ought to be done. On the other... He will have plenty of new chances to find the right level of severity and beating the same two pairs of cheeks again and again after they are already black-and-blue is not the most realistic training either.

"Let's split the difference", she finally says. "Do a few harder strokes to get a feel for it. In real discipline you might do this, for example, as a warning for a first mild offence of a particular kind". "S-sure", Daniel nods and picks the paddle suggested earlier, as Neha braces herself, trying to glare at her older cousin. The younger girl quickly looks straight ahead again, however, once she sees Daniel turn.

The young man settles on four strokes, which he starts delivering without too much confidence, but Rhea's expression makes him put in more of a swing and the weight of the paddle itself makes itself felt. Neha stays silent throughout the paddling, but oval shapes begin to form on her cheeks. "That was better", Rhea says once Daniel lowers the paddle. "Do you want to say anything to the girl you just punished or do expect her to say anything to you?" To both cousins' surprise, Daniel actually manages a full sentence. "I hope you learnt your lesson. The next time it will be much worse. Now get up... But keep your panties down until the end of the punishment".
