MKMP-113 Giving her sister-in-law an aphrodisiac and the ending

Try the aphrodisiac Kizuna Sakura. At first I was skeptical, but gradually it showed its effects. Control of the body and emotions becomes impaired and sensitivity increases, breath leaks and sexual desire increases. Kizupon is too sensitive and makes sex more pleasurable than usual, and goes crazy from one climax to another. The appearance of being seduced by sex and addicted to endless pleasure is truly erotic.
