again, as Ive stated before, falling to the side simply lets him complete the crank.....being turtled on my knees is whats stopping him from flexing my back in the first place....if we fell to the side, or rolled over so he was on his back, he can finish the crank easy.
Im pretty flexible, but the way he locks it around my waist, I seriously doubt Im going to be able to swing it around and hook his foot......when he his triangle is locked deep on the side of my hip, there is no possible way to wrap anything around it...humans just cant bend that way!
