NACT-028 Uncle Gacha!? Draw an experienced, erotically skilled uncle! Azu Amatsuki

Azu, unable to meet up with her sex friend, is bored and has too much sexual desire. On a whim, while taking a walk in the park, she picks up a ticket for a suspicious "Uncle Gacha" (gacha game). She heads to the venue half-believing it, but then, just when she's completely forgotten about it... an unusually large and heavy package arrives. The cardboard box begins to rattle and move, revealing the prize: a masochistic uncle!
