The actual spanking in this forest spanking video from Brutal Punishment doesn’t seem unduly severe to me, but the thin model-type (identified only as “pain slave Amy) who is taking the punishment? She hyperventilates and cries and shrieks and dances around as if she’s being beaten within an inch of her life.
She’s quite plausibly distressed (as you can see in some of the sample gallery photos) by this spanking, so either she’s a better actress than she seems or she’s performing near her limits for this shoot:
Brutal Punishment is part of Fetish Network, a group of more than 40 sites (with 3,500 videos and 1.5 million photos) that’s sold as a bundle for your single subscription price (as low as $24/mo). Other spanking sites in the network include Elite Spanking, Perfect Spanking, and Punished Angels, so it’s really rather an excellent deal for spanking fans!
