My Girlfriend's Little Sister Moved In opens with a gymnast, Lea Fontaine, moving in for four weeks ahead of a major competition. Her stepsister works days, which leaves the boyfriend as training partner. Five episodes of sly flirtation, playing on how much the girlfriend fails to notice.
Premise and first two chapters
A month-long stay ahead of a competition three weeks away brings a gymnast into a couple's home, and her training starts before her stepsister leaves for work. Lea Fontaine stretches every morning and asks the boyfriend to help, holding each pose longer than feels comfortable. The girlfriend is delighted to host her and hopes the two will get along. He thinks a month of this is more than he can survive. Lea wants a willing partner and seems to enjoy watching him squirm; he wants to stay faithful; the girlfriend wants a peaceful house.
Episode 1 introduces the visit, the early training hours and a stretching session that ends with Lea teasing him about what he would like to do. In the second episode she turns practice into a game in which he scores her routines out of ten, then asks whether he would keep helping if her stepsister walked in. The stepsister comes home and heads to bed exhausted. Lea then wonders aloud whether her stepsister is a heavy sleeper, and how that night plays out with the girlfriend just down the hall stays unanswered.
