In order of preference; 1 being the most preferable 1) Step bare footed onto an upturned 3 point plug 2) Trap your finger in a slammed door 3) Step bare footed into a group of stinging nettles 4) Passionately kiss your Mother in Law. Tounges.
I often dream about the day I am able to smash my mother in law all over her living room while the missus is in the toilet or something. Pretty sure I can do it in two minutes flat.
1. Nettle stings are said to be therapeutic 2. If tantrics can walk on hot coals then upturned plugs must be a cinch. 3. finger in door ... ouch! but the throbbing afterwards is curiously interesting. 10. MIL's been dead for 10 years but she hated me anyway... if I did she'd have to take her teeth out first
Three-forked plug. If I knew I had to step on it then I'd be able to control how hard I pressed down on it.
What about if you undressed the mother in law and she was wearing this particular bra? You're not allowed to remove throughout said intercourse. Bert & Ernie must watch you for the duration of the event.
