[Nagashiro Rouge] Futari Asobi Tomodachi ♀♀ Doushi no Baai Ch. 1

Two schoolgirl best friends turn idle pillow-talk about masturbation into a hands-on lesson when the boyish one of the pair coaxes her busty friend Eri into letting her do the touching. Giggling instruction gives way to flushed curiosity as she kneads Eri's heavy breasts and teases her tips, then both girls decide they'd rather learn together, shirts falling open and fingers slipping beneath plaid skirts until they're pressed chest to chest, moaning into each other. Chapter one of Nagashiro Rouge's series captures the giddy moment friendship tips into something wetter, ending the pair tangled together and nowhere near done exploring.
