A manual for exploring female sexuality. During an interview, a 31-year-old temp worker and amateur woman named Yui candidly reveals her embarrassing sexual struggles. She is single and wants to satisfy her masochistic tendencies with her last husband who doesn't understand them. She says she gets flushed from H talk, swoons during kisses, enjoys having her neck squeezed, and thrusts a penis deep into her throat, continuing even when she gags. She says sex with her boyfriend isn't satisfying enough, so she squirms and reaches multiple orgasms during caresses. She becomes addicted to being penetrated from behind and spanked on the ass, reaching ecstasy by sticking out her tongue to receive semen. Afterwards, she inserts a dildo stuck to a mirror or floor into herself and reaches ecstasy again. In the shower, she is made to swallow water while standing in a doggy style position. On the bed, she desires more abuse, asking for spanking, and finishes simultaneously during neck-squeezing sex.
