UMD-1018 I tried using the much-talked-about, super intense energy drink Sensitivity Boost with my sister and girlfriend, and things got wildly out of hand!!

A boyfriend has recently felt that things with his girlfriend in bed just haven’t been going well. Wanting to make their intimate moments amazing, he buys a certain love-enhancing liquid online. This mysterious, tasteless, and odorless fluid is rumored on social media to be a magical potion that boosts desire. Although he gathers the courage to buy it, he thinks it would be risky to use it on his girlfriend right away, so he decides to test it on his older sister first. When he secretly tries it on her, the effect is overwhelming, far beyond the rumors. After the experiment succeeds, he finally gives it to his girlfriend. However, the potion works even more strongly than expected, leading to an unexpected turn of events.
