Ty wasn't thinking about, but Tae would have known that her parents sent her to a special boarding school dedicated to spreading their culture throughout the world. To do that, they would need more people - and that meant more couples. So they provided free relationship counseling and sex health materials. Ones that could both prevent pregnancy and ensure it. Tae had been convinced by "that guy" to take the morning-after pill that ensured it.
As Tae wondered what to do with her day, a memory cropped up of her having relationship counseling with "that guy" first thing in the morning, followed by a medical checkup. "That's odd," she thought to herself, but memories came to her of the school being very open about experimenting with sex to find the perfect partner, and further memories still came of her hearing about this guy from school matchmaking services. "Whatever," she thought, and got up to get changed.
Deep inside Tae the embryo had long finished attaching to her uterus wall, and pumping her body full of maternal hormones. The morning-after pill catalyzed the reaction, causing her breasts and ass to be sore from the beginning of their expansion that would help her attract a permanent caregiver and mate. Tae gingerly selected a larger bra from her collection, and soft satin panties that wouldn't be so tight. Then she pulled on a black nylon top and a very short skirt with silk stockings, each of which had the opposite red and black checkerboard pattern.
Tae spent the rest of the time getting ready on her makeup, feeling a growing need to look her best for "that guy". Her body was priming itself for imprinting; whoever fucked her next, her body was going to latch on to his DNA and become helplessly addicted. Daydreams of "that guy" bending her over the table in the counseling room and filling her up with his world-shaking cum flit through her head until she was ready to go. Tae slipped into her slim black heels and shook her head; not sure where all these fantasies of being claimed and fucked into submission were coming from, but it would soon be explained to her at the relationship counseling meeting.
