My sweet best friend and mama

Marco Rossi (An male alpha) marries and impregnates Tarma Roving (An male omega) via anal penetration, his best friend and comrade in mid of their 40s, because both of them plan to becoming parents to this age at being retired from the Peregrine Falcons (Also, there is a POV secuence since Tarma's omega uterus, since his ovum is fecundated by Marco's sperm until the birth of his baby girl via C-section)
