This doujin is probably the single most comfy doujin we have on offer.
It starts with Suzuya lazing around in Admiral’s house during a job break (a flashback shows they spent the last two days having sex non-stop), when suddenly Kashima and Haruna drop by. Jealous that Suzuya had the Admiral for herself for the whole two days, they start smothering and pampering him. What follows is the chillest, comfiest and slow burning foursome you’ve ever seen.
