Well I guess it depends on who's giving her the punishment.
Would it be a member of her family/a friend, or yourself?
Personally I think that she should be tied to a tasteful coffee table (ropes attached to all her limbs, each end tied to a table leg and very taut (and of course somehow tied in such a way as to make her juicy bits exposed).
then whoever is punishing her should rifle through her college bag and bring out her pencil case, and empty the contents onto the floor, then select a nice fat pen and ram it into her cunt. (is she a virgin, sexually experienced or not?)
then take another pen or pencil and insert that too, just as roughly, keeping on going till all her pens and pencils and maybe brushes are crammed into her tight hole. Of course the more you put in, the more she cries out.
I'm suggesting this as I'd get endless amusement out of doing this to a girl, slowly too.. and I'd make sure I had plenty of pens.
This would only be the start of her punishment, if it were me I'd slap and whip her breasts, twisting her nipples hard.
I'd probably cut some root ginger and apply it to her hot little clit too, and watch her squirm.
Oh, and maybe turn her over and give her ass a good flogging.
My thoughts aren't very organized, I have quite a number of ideas!!!
tell me what you think so far.
