As a freshman at college, Yamamoto joins a sake club to meet girls and finally lose his virginity but, later he realises that there are only men. At a club trip he mets Kobayashi, a club member who's family makes sake and is a virgin as well but because his enormous member. After getting drunk, Yamamoto takes pity of Kobayashi situation and decides to give him a hand... Well, his thighs and later, after a lot of preparation, the opportunity to thrust his gigantic member in his ass.
It's a lovely story. They are so innocent and cute about their feelings for each other and a perfect match without even try. It's definitely a favourite of mine.
