Chris Redfield always takes photos when he trains to see the progress of his muscles. On this occasion, something happened, because while he was taking a photo, a part of his body began to take on a large size.
Chris was having an erection. Chris would take advantage of this incident, as he began to take more photos while his penis became firmer and his erection became firmer, the more photos he took, the firmer and harder his penis became.
Chris would not stop until he managed to capture how his penis would spew a large amount of sperm onto the gym glass.
