Sexy and crazy Knut at his best:

Charlie is lying on the couch, chilling in front of the TV.
Knut is with him but can’t sit still for a second.
Instead of relaxing as well, he keeps fidgeting around, doing workout exercises, and constantly trying to motivate Charlie to join him.
Charlie gets increasingly annoyed - especially because Knut keeps insulting him, calling him too fat and claiming he does too little for his body.

Suddenly, the DVD player starts playing an old Fightplace movie in which Charlie can be seen fighting.
Knut immediately begins making fun of Charlie’s fighting skills.
That’s finally enough for Charlie: he grabs Knut and throws him onto the mats.
The fight, which still has a few surprises in store, begins half playful and half serious.
Even though Knut receives several smacks on his ass, he keeps provoking and challenging his friend.

At some point Charlie has had enough and forces Knut to surrender.
Knut takes the defeat lightly and heads into the bathroom. Apparently, the wrestling turned him on a lot.
After taking a shower, he watches some porn and jerks off.

But even afterwards the sporty guy still hasn’t had enough.

Dressed in a hot body outfit, he calls out for Charlie and demands a rematch - a challenge Charlie naturally doesn’t refuse.
