Midnight Hitchhiker
When you're lying next to your partner (preferably when they are sleeping but awake works just as well) adjust your hand into the hitchhiker position (thumb up) and launch your thumb directly into their butthole. After insertion is complete, make sure to thank them for the ride ;)
While in the spooning position, Rafaela was sleeping and Sebastian gave her the midnight hitchhiker in order to wake her up so he could get another ride aka sit on his dick.
