Double TK Farm Bull

A robust young man with a strong body, the boss smiles and hands over a bottle of "free protein powder". Without thinking much, he drinks it all in one gulp.
Before long, his consciousness blurs.
When he wakes up, his limbs are tightly bound, everything in front of him is pitch black, and his body is completely unable to move.
The boss and his friend approach from left and right, their hands constantly playing with, stroking, and TK... his sensitive areas.
Until he's completely drained, not a drop of essence left.
