Yuki gasped and tried to pull away again when the elf pulled out his manhood, though with her legs and arms shackled she wasn't going anywhere very quickly.  A loud gasp escaped her lips as he thrust into her, and she squirmed, determined not to feel any pleasure at being raped... but failing miserably thanks to the spell, soon panting and moaning lewdly.  "No... no, please..." she tried to beg between moans, "don't get me pregnant.  I need... I need to find my people, I can't be stuck having babies..."  She could feel her body betraying her however, her sex growing wetter with each thrust, and she knew an orgasm was building soon.
