Friends of Jerk

In the early afternoon, Tim, Walter's 22 year old son, was sitting on the sofa in the living room of his college apartment. with his roommate Martin.
A laptop was set up in front of both of them, on which some entertainment was running. Both holding a shisha hose in one hand and another hose in the other, jerking off on the screen. There were a few beer cans on the floor.
In addition, a suggestive rap song ran on an endless loop, in which the main part of the text seemed to consist of "I am the sexy girl".

"Man Tim, I really can't believe what your father did there!" roared Martin between two moves at the shisha.
"Yes Martin, really, believe what my crazy inventor father did!" began Tim.
