Norainu no Yoru

"When I touch the right spot, even an Alpha can feel good." Eric, a detective and an Alpha, is investigating a case when he is suddenly injected with a "rut inducer" by a street thug. When he collapses in the street, he is taken care of by a doctor who calls himself Lean, and spends the night at his house. Eric, whose rut won't dissipate, asks for Lean's help to make him cum, but... "Not enough... still not enough." Just like that, the two are drowning in sex, devouring each other like animals. Is this encounter a coincidence or destined? Don't miss out on the full-blown sexy omega-verse until the end.
