Just look how vulnerable she is without her limb enhancers. Before the episode "Beta", I always fantasized about Lapis beating the shit out of her after getting annoyed at her being loud or talking too much.
Eventually, Peri would just keep more to herself, because she didn't want to upset Lapis, and actually wanted to be her friend. So she starts behaving like a pearl would in homeworld, observing Lapis' daily routine and adapting herself to it.
Lapis would eventually notice this behaviour and occasionally take advantage of it, ordering Peridot to blow her or fucking the little bitch while ordering her to beg for more, and Peridot would, even if she didn't want more, she would beg for more and say it feels good to be fucked even if it hurts. She would do anything to make her barn mate happy.
Anyway, i wanna lick her blood.
