While waiting for the repairs to the apartment he's currently living in to be done, the alpha Shiiba was looking for a temporary house to live in. That's when he found an advertisement for a shared house addressed to alphas! But it turned out that his roommate was actually an omega, Asaga, who proposed a contract to him!! In order to live there, he'd have to become Asaga's sex friend, to suppress his heat. As Shiiba was perplexed about the proposal, he couldn't fight Asaga's sweet and captivating pheromones... so he found himself thrusting furiously inside his melting, special place! Even worse, Asaga's invitation to go even deeper made him lose his mind, so he ended up pouring a lot of his hot semen inside him...!!
