Instead of using it, you can always use Mako as your sister-in-law. Hyuga Hikage

His older brother-in-law, 'Hikage' (hikage), is subjected to sexual atrocities on a daily basis. "Hikage-chan can't go out, so I'll go shopping instead." My older brother, who smiles with a cramped smile and is tender, always asks for a return. "I've been using it, so please feel good." An older brother estruses a hardened crotch by scraping it on his eyebrows. I'll sit in the room until I ejaculate. Everything becomes troublesome, and Hikage accepts the requests of his brother. However, my brother-in-law's sexual desire gradually started to run wild.
