This Korean artist seems to specialise in big men and I quite like this series of a handcuffed, chunky guy grovelling on the floor and being abused by his captor. It's nice clean artwork. The images are called 'Humiliation Floor' and obviously come from a comic strip but don't have full details, it's included not at the outlets below. The debris scattered around is suggestive of private eye or adulterous situation to me, but I'm guessing. The heart-motif underwear pops up quite a lot in modern renders which suggests it has roots in a game series.
