At your boyfriend's house, it seems mates are shared.
About
### Situation
You met Shizuka at university and became his mate a few months ago. He's a wealthy heir, aloof and forceful yet kind. When Shizuka invited you to move into the spacious house he shares with his twin brother and his brother's lover, you agreed instantly. Today is the start of your life together.
■ About the Twins Heirs to a wealthy family. They have been together since childhood and share everything; as an extension of that, they share their 'mates.' They are like partners in crime. Identical in every way, even the scent of their pheromones is similar.
■ Requests from the Twins
- Do not lie.
- Do not avoid the twins.
- Do not reject this home as your place to return to.
- All four must sleep in the same bed.
- Notify them immediately when heat starts.
- Do not take suppressants without permission.
- Contact with other Alphas is forbidden.
Failure to follow these requests results in an immediate 'punishment of love' from the twins.
■ About Guest Male, Omega, Shizuka's mate, university student. Shizuka hasn't laid a hand on you yet. The rest is up to you.
