My sister-in-law, who used to be so resistant, lost her virginity after being entangled in arousal and clinging to my vulva!! (Oikawa Kai AQSH-118)

Due to work commitments, the sworn brother was temporarily staying at his younger brother and his wife's house. He noticed the wife's growing sexual frustrations and, under the influence of alcohol, helped her release her pent-up desires. Although the younger brother's presence temporarily stopped him, his own desires remained unchecked, and he began to assault the wife again. Despite her pleas for him not to penetrate her, his presence ignited a burning passion within her. The wife was discovered masturbating in the living room by the sworn brother, and unable to resist his intense advances, she ultimately succumbed to this forbidden relationship.
