[Iwami Kiyoko] My Girlfriend's Not Here Today Ch. 12+17

With her volleyball-obsessed girlfriend Nanase tied up in club activities, Yuni drifts into secret poolside encounters with other girls, torn over whether their affair should stay hidden. A possessive blonde lover pulls her close, demanding she promise never to remove her piercing and cooing over what a good girl she is — even while scolding her for failing to reassure the girlfriend she's betraying. Secrecy, jealousy, and hungry kisses tangle together as wandering hearts learn that stolen afternoons always come at a price.
