Gitai Saimin Episode 1

Meet Murakoshi Shinta, a student with a wild imagination that he's kept under wraps while leading a rather dull and dreary life. But everything changes when a tentacled alien parasite decides to make his penis its new home. Talk about an unexpected twist! Feeling understandably awkward about strutting around with his groin on display, Murakoshi voices his concerns to the alien. But the creature isn't worried; it promises that no one will bat an eye because it has the power to mess with people's perceptions. With this newfound ability at his disposal, Murakoshi decides to indulge in his deepest desires. What could possibly go wrong?
