Hiro’s heart is beating fast, faster than usual, baymax knew about it, he in fact knew exactly why was it. Aunt cass left for shopping that morning, Tadashi had a meeting with his friends and was expected to come home later that day, in the meantime Hiro explored his body, every part, he knew every corner and twisted turn, he laid in bed, in Tadashi’s bed, he just laid there for hours if possible, this time though, he is laying completely naked, letting the summer air fill his lungs and warm his skin. He had been touching himself for several minutes now, his erect penis laid in a black ‘pillow’ of hair.

Before he knew it, his manhood was also as hard as his brother’s
