Amnesia
'Told you you liked my cute titties! But from that look you're giving me I don't think any of that jogged your memory.' She frowns. 'I guess we'll have to go back to the pain. Oh, what a shame!' She smiles maliciously and fetches a cane from the dresser.
'I think that twenty will do this time. One for each time I've made you scream.' She winks and begin hitting you. [20 hits with the cane or ruler in each spot: inner left thigh, inner right thigh, right tit, left tit (at least 5 directly on nipple), tummy.]
'We have had so much fun with this! Once you dressed up like a slutty little schoolgirl for me, and I was the big bad teacher. You were in detention for cheating and you had to be punished. I spanked you with my hand till your ass was bright red, then I made you bend over a desk and write lines while I kept caning you.' She giggled softly. 'Except, every time you stopped or made a noise or your hand slipped, I added a hit! It started off as ten but by the time we finished it must have been over fifty! You were dripping wet after that, but you had no relief. You just ate me out till I came, then went and made me dinner.' She laughs harder and stops hitting you.
'Hmm, your pussy looks a little neglected. Especially that little clit. I know just what will help!' [Using the cane/ruler, 10 hits on your pussy, with at least 5 directly on you clit].
