He, He, and Another he only for one and only him

it's a Bl fiction story.
people who are integrated into threesome foursome between bl couple can read it.
I suggest only 18+ will read it.
it can stir up your inner sex desire so be aware.
A young in his 20 how he ended up with his 3 boyfriends two are twins and the other one in his mid-thirty but sexy enough to make him fall in love with anyone.
