Your new heroine, Rena Kawaguchi, tries soapland work for the first time. Nervous but determined, the adult college student learns the trade's signature techniques: sucking an unwashed cock immediately upon meeting, going straight into sex and washing a client with her foam-covered body. She also attempts the diving chair, periscope and other classic soapland positions. Though she is meant to provide the pleasure, her body is so sensitive that she trembles into genuine orgasms, delivering a bubbly girlfriend-style fantasy.
