Shy 19-year-old adult Subaru Wachi still is not used to having sex in front of other people. But once a cock enters her, she forgets everything, surrenders to pleasure, and moans in a piercing voice. Taking on S1's popular Eros Awakening series, she reacts intensely to sensations she has never experienced before, convulsing uncontrollably and squirting in enormous bursts. Mortified by her own body's response, she says she is going to lose her mind from cumming too much—then climaxes all over again.
