This is how I ended up by accident with Hazel when I got her to wash her fluffy butt. She's much more flighty than Butters (who got washed first). I had her in a forward facing hand scooped under her position with my other arm over her, and Hazel would not settle, and walking toward the house we were suddenly doing a scramble of my hands, her chicken legs and wings, and then she ended up there and immediately stopped struggling, though she probably got hot & tired. I wasn't clamping her much though I had a firm grip on her legs, supporting her with that arm. She fit my body really well that way.
