[Justin Bieber]

Mounding is the practice of taking a males genitals and [shoving] them up in the body [cavity]. The end result is that he only has a “[mound] that resembles a cunt.

[Merna]

Inserting pillows under the hips of a girl lying on her stomach, [mounding] her ass upwards....providing [easy access] to her [sweetspot] and a spanking target that cant be resisted.

[Britney]

The art of lying perfectly still while completely covered with blanket. The traditional colour of the blanket is orange, but a [sleeping bag] or [poncho] is an acceptable alternative. Mounding is more effective when done in public and is considered a legitimate recreational activity.
Pillows can be used [under the blanket].
