Musubi and Minato woke up in her room, and the two of them just looked at each other in loving awe. Miya, surprisingly, just let the two of them have their privacy. A huge-breasted Sekirei then jumped in through the window, and greeted Miya. Her breasts were about five feet in diameter, and she had Byzantium purple hair tied into pigtails, and she had vermillion red eyes. As big as her breasts were, she moved with elegant ease and agility. They weren't heavy, in fact, but they were dense. They were solid, but rather wobbly and bouncy. She was dressed in a kimono the same color as her hair, black shorts, and black slippers. Miya then nodded to her, and she snuck into Tsukiumi's room, and snuck a powdery substance into her nose.
Miya nodded to her and said, "Thank you, Bakunyu, you can be off until I need you again." The Sekirei nodded and said, "Right-o, Miss Miya, Ma'am!" Bakunyu jumped out of the window, while something was stirring in Tsukiumi's room. Her breasts had instantly expanded to five feet in diameter, and she ran into the hall, having a bit of trouble with squeezing her new, big and bouncy assets swinging around. She looked at Miya, and figured she wouldn't know about it. She looked into Musubi's room, and found Musubi in the same situation as she was. When she saw Minato, however, the two of them got into an argument, which was rather cut off by their equally-massive assets.
Musubi and Tsukiumi now had breasts five feet in diameter, which were light, but dense, and they moved with the grace and agility they had before. Minato had to split them up, but everything worked out in the end.
