Imagine visiting a time-reversed world in Taiwan where you meet two Chinese dykes in their bedroom un-erasing "我们是女同性恋在我们的房間里互相摩擦外阴" with the whiteboard duster, before un-writing those words from the whiteboard with their markers.
The sexy part begins when the three of you gets naked for a threesome where you watch them rub their scissoring pussies against your dick in between, before the cum from their bodies gets vaccumed back into your dick, all the while hearing their backwards-ized dirty talk in their ugly-sounding language.
