You've Got Mail: The Perils of Pigeon Post – Fei Ge Jiao You Xu Jin Shen, Vol. 1

It's not easy for a man pushing forty to meet other gay men while living on the outskirts of the Great Xia kingdom. That is, until the perpetually-single Wu Xingzi catches wind of The Peng Society for Gentleman—a top secret club for men to meet each other and perhaps even exchange lewd ink drawings of their personal anatomy via pigeon post. What was once a faraway dream for Wu Xingzi has quickly become his new purpose in life: to collect as many shockingly detailed phallic illustrations as he can! There is just one problem. His favorite specimen belongs, in the flesh, to the notorious Guan Shanjin, a man of ill repute who is intent on thrusting himself into Wu Xingzi's world. Will their encounters become too hot for Wu Xingzi to handle? Or will they find themselves both coming back for more?
