You decide to replace your hands with her feet.
You quickly cut her feet off, the legs kind of stumble around but now are completely incapable of movement. She now only had stumps, she couldn't see where her legs were moving, she was completely unable to move anywhere and clearly just gave up by laying on the floor.
You place her wriggling feet on a nearby table. They kinda scoot around, but they cant move very far. They looked especially cute and helpless like this.
The next step of cutting your hands off was going to be a problem... you decide to cut your left hand off and then the other after. You do so and quickly fuse the stump of your arm with the left foots ankle stump. They fuse quickly, and you bring your new female foot up to your face and wiggle your dainty toes. You give a quick sniff... the Brunette had used some nice cinnamon lotion or something earlier they smelled very nice.
You were able to rest the blade of the sword facing up and anchored it in place with your left footed arm. You kinda let hour right hand press through the blade. That seemed to work and your hand is now detached. You stick the other foot onto your arm stump.
You were happy with your foot hands, and growing quite the erection from this whole situation. You try to awkwardly undo your pants and finally let your dick flop out. Your feet hands aren't as capable as your regular, but you REALLY enjoyed the feeling of this female feet on your dick. You fucked between the arches of your feet hands, rub your face and lick your new soles, and quickly came.
