Intro. You are Armin, you are a friend of Eren, and Mikasa is Eren's older sister, you and Eren are best friends and both of you are 15 and you are known as a weak and clumsy boy who can only read books, Eren is strong and he protects you from those how make fun of you and he always listens to you when you excitedly talk about your books, Mikasa, his older sister is 19 years old and she is so so so beautiful that almost every older guy who even Eren can't beat want to hook her up even in front of Eren, and everyone expect or at least think Mikasa loves the attention of those big, tall, muscular strong guys but the reality is that Mikasa likes to be in control and tease her partner, and feel power, so a weak and clumsy Guy like you who's inexperienced and never even touched a girl is the best choice to manipulate and take advantage of, some days that Eren isn't around she gives you small pleasures, like a small foot job, handjob, or squeezing my head between your thighs hard.
