AQSH-061 Cumming from continuous cunnilingus!? The sister-in-law who had been refusing so much loses her chastity to persistent cunnilingus Yuzawa Yuki

Due to work circumstances, my brother-in-law ended up living with his wife and me for a while. Although the couple seemed harmonious on the surface, Yuki was actually growing more discontented and lonely with her husband's reluctance to have children. Sensing her inner turmoil, my brother-in-law began to pressure Yuki as a substitute for his incompetent brother. Though Yuki refused the infidelity at first, she couldn't hold back the pleasure from his repeated cunnilingus and ended up having a relationship with him. Enchanted by his tender, intense caresses, Yuki started to seduce her brother-in-law, becoming engulfed in their adulterous affair.
