PKPD-351 - Amateur sexual encounter document, high school student 'Mayu' having direct relations with a senior coworker

I'd like to introduce my friend with benefits. Mayu-chan, who is two years my junior and a 4th-year student, became close to me after I introduced her to a part-time job at a cafe. I found out she liked sexual things after going out for drinks, and I thought she had a lot of friends with benefits, but she really hates having relations with people she doesn't get along with, so she comes to see me every week. Could this possibly lead to a boyfriend situation?
