[Nanatsu Fuji] The Marks of Summer (Oneshot)

After announcing their first overnight summer trip, Sayaka nervously follows Natsuki onto the beach, where Natsuki urges her not to just stand there spacing out and to let's go. Natsuki pulls her close, whispering that the thought of others seeing her body is embarrassing, yet she’s fine with Sayaka seeing her. The heat of the sand fuels a private, teasing intimacy as Natsuki kisses and pinches Sayaka, turning the vacation into a charged, secretive encounter.
