Rika started dating after being confessed to by her childhood friend Hikaru. However, Hikaru's penis was so small that she didn't immediately notice that it was all inserted. On the other hand, Saburo, another childhood friend of hers, also has feelings for Rika. By chance, Rika sees Saburo's penis and is surprised at its size. Saburo wakes up when she can't control her interest in the drunken Saburo's cock and she touches it. And then, he saw through that he wasn't satisfied with Hikaru's cock and was raped.
