Plot Summary

SSIS-685: A hot spring trip with Ayaka, a mistress who has all the looks, personality, and sex, is always the best feeling, and every time is a memory of a lifetime. The lewd appearance is irresistible as if a switch was turned on when you kissed. Soak in hot springs, have sex as you please, and drink alcohol. Next to him is a matchless beauty. I can't find any words other than excellent.
