Fresh from her comeback, Serina Hayakawa shows off her slutty side in this M’s first appearance! This beautiful woman, who hasn’t drunk semen for about seven years, gulps and gulps like a hungry beast from the get-go! She shows off her gulping repertoire to the fullest, sucking with a straw, gagging with a mouth opener, pouring it onto a mirror board, drinking continuously, and more! Her lewd drinking technique is the best among all active AV actresses!
