Redhead teacher explain the science of but plug

The science in each but plug ever inserted in a female anus is very tricky, it begins with the lube that is needed to grilse up the plug this babe is inserting so it fits easily into her amazingly constricted rectal hole and allowing it to make it pop when needed by easy contracting of her a-hole muscles, whilst that babe gently fits a sex toy inside her slit and occasionally her skinny fingers and even hand.
