[Inanaki Shiki] Ashi-san Saki Saki Manga (Yahari Ore no Seishun Love Come wa Machigatteiru.)

A late-night encounter finds Hachiman Hikigaya coming to the rescue of a wobbly Saki Kawasaki, and one thing leads to another before her jacket hits the floor, baring the huge breasts he can't stop praising. Their privacy doesn't last—drunk Yumiko Miura, stinging from her boyfriend's cheating, catches them mid-act and turns heartbreak into a challenge: whoever satisfies Hikio best wins. What follows is a sweaty, breathless ffm threesome of leg-locked rivalry, the beauty-marked ponytailed Kawasaki and the fiery Miura taking turns to prove who can break his composure first.
