Uwasa no Futanari Gal wa Hatsujou Shiteru.

Two futanari gals find themselves stood up for a "papa" date.

Saseko had been abstaining for a week in anticipation,
which surprises her partner, Yariko. Eager to verify the results of the abstinence,
the two, overflowing with pent-up desire, indulge in a futanari yuri sex session.
