I got a call from my sex friend, who I had great chemistry with, for the first time in three years... and the reason was obvious: she wanted to have sex. "It has to be you... I've been waiting for sex like this for so long." She couldn't be satisfied with any other man she had sex with, so she came back to me. "I wonder what will happen if I drink this?" The aphrodisiac that Yui brought with her was so effective that she went crazy and got creampied over and over again!
