Sexual position originated in Brazil.
Here's how to do the "canguru perneta"
1- The couple should stand and with their bodies glued to each other
2- It is important that one of the two stays against
the wall, to avoid falls
3 - The woman lifts one
leg around her partner, facing him.
4 - The man holds the woman by one of her thighs while she supports only one foot on the
floor (hence the name one-legged 'perneta')
A curiosity: the term kangaroo exists because the partner needs to
jump, if she is smallerer than the man, allowing the pace of the transaction and the sensation of penetration.
