Sometimes the simplest contraptions are the best. Just take a naked Ashley Bulgari, make her kneel in front of a steel cross and lock her wrists to her waist! Oh, and remember to make the side pipes just long enough so she can not slip her elbows over them. Take your time shooting some pictures and video, until her knees start to hurt because the floor plate is not as soft as it seems. Then, after about 45 minutes, give her the keys to unlock herself and rub her knees. You will notice she is a lot more submissive than when we started. This is what we call cross training!
