[Takashiro Go-ya] We're experienced ch. 1-5 [Skeletan Hand Translation tm]

A loyal childhood friend's world flips when she discovers her best friend Nanami has a secret boyfriend, so she tails her through the after-school streets — swearing not to lose her — only to stumble into a hidden affair that drags her straight into Kenji's arms and an ffm threesome she never saw coming. Sweat-drenched and ahegao-faced, the two girls get thoroughly claimed through sneaky voyeurism, nakadashi finishes, and even a bathroom scene where the doting sole male pauses mid-threeway to grill them about their grades, their teachers, and whether their parents are worried. It all builds to a breathless 'I LOVE BOTH OF YOU!!' as the pair surrender to sharing him completely.
