   Summary

   After silently observing various people flirting and some likely going much further than that, Senku decides that it’s best he develop some sexual protection to avoid unexpected pregnancies.

    

   Story started mostly as a self-indulgent way to get Senku wrecked, but I started adding way too much plot and character development and it was fun! Hope you enjoy all the things I've made up about Magma.
