Please, my long-lost cousin, teach me how to use anal guns! (Kawakami Nanami, DVAJ-136)

I reunited with my cousin after 5 years. She has now grown into a beautiful young woman. I recalled the scene from 5 years ago when I caught my cousin trying to masturbate my brother. So I asked my long-lost cousin to teach me masturbation techniques. Of course, the end result is inserting it into her vagina and fucking her until I feel good!
