Rina, a kind-hearted female college student dedicated to cat protection activities, decided to offer her body to an old man who loves big breasts due to financial struggles... The old man's abnormal 'breast harassment,' tickling restraints, aphrodisiac oil, nipple torture, and wild bouncing paizuri sex... While confused, she indulges in unknown pleasure and her reason crumbles. This is a record of a female college student reaching depravity, desire under the name of assistance, and being dominated by big breast training.
