I'm trying to find the right spot here, but your legs are feeling heavy, heavier than I thought they would be, and you're still wriggling a bit, but I hear your groans so I know something is working here. I try to get my feet spread wide enough, but then I feel you tug on my hair. And tug is an understatement. It's more like a yank.
Very much like a yank.
At first it just pulls me back more, which pulls up your legs more and strains your back still more (spine compression, yes!), but then I start to feel an intense strain on my knee and an even worse one in my hip as you seem to be pulling me off to the side. My arms are already fiercely straining to hold onto your legs and this all starts to pull me off balance. I can't keep hold of both of your legs so I drop one and just try to focus on the other, using both my arms on it and focus too on just one of your hips, as I try to regain my balance
I'm still finding myself being pulled off to the side, but maybe I can do a little more damage while I still have a hold of you. My face feels like it is contorting a little as you continue to yank on my hair. I let out a groan but not a scream, but maybe it looks like I am about to do that
Scream
I hope you do some screaming here
