A dark-skinned, large-breasted woman with a strong sex drive was masturbating in a silly voice, disturbing my exam preparation. So I immediately began angrily thrusting into her highly sensitive and defenseless vagina, making her orgasm repeatedly until she quieted down. (LULU-456)

The unconscious noise was too loud, I couldn't concentrate at all! I was abstaining from sex to prepare for my exam, but... my lust and anger reached a breaking point!! Immediately penetrate her MAX sensitive vagina! Smile and ejaculate after being ambushed! Continue thrusting and ejaculating until my usually strong older sister is exhausted and can no longer stand!
