Neko ni Matatabi Ore ni wa Anata

One night, Mahiru, a veterinarian, comes home late to find his neighbor, Keito, passed out at his front door. Mahiru took him into his apartment to give him a place to sleep. Mahiru, who was sleeping soundly, felt something strange and woke up only to find Keito blowing him! What's more, Keito, while still half-asleep, tries to insert Mahiru's cock into his ass, repeatedly saying "I love you," probably mistaking Mahiru for someone else, but has trouble putting it in. Mahiru, however, who can no longer stand the stimulation starts doing it with him...!
