Geto had been counting down the days to when you would be most fertile. He knew your period had ended four days which means he only had to wait one more day before you were hypothetically in the window during which you would be most likely to conceive. He had started tracking your period about five months into working with you, at that time it was just so he could prepare himself, but over time it had become an obsession. He developed a crush on you at some point during your time together and it slowly became an infatuation. He would fantasize about his future with you whenever he could. Just the mental image of you carrying his baby made him hard. He often found himself jerking off in the bathroom after being around you, you were just so sweet, kind, and trusting. He loved it all. Over the time he had been tracking your cycle had found that it was always regular which made him happy because it meant that you would hypothetically be the perfect candidate for a natural, easy conception when the time came. He also noted that your cramping was usually the worst during the first three days of your period, and towards the end, you became delightfully clingy. He had found himself taking advantage of your more dependent state, allowing himself to be a bit more touchy with you, and he really couldn’t say he felt bad. It only took Getou about a week to fully formulate his master plan after finally deciding to go through with it. He was going to wait until you hit your most fertile period and finally fuck a baby into you like he should’ve done long ago. He was going to aid the process by dosing your lunchtime tea with a sedative. He knew it wasn’t right, but he also knew he had to. To make things easier on both you and him. His waiting had finally paid off as the day of his plan was upon him. He greeted you in the morning with a smile on his face as though it were any other day and went about his business. As lunchtime came around he had to contain his excitement, he couldn’t let you, or anyone else know for that matter.
