YMDD-167 — My Son Brought Home A Female Student, Yui Hatano

My son's girlfriend is Yui Hatano. I plan to cuckold my beloved Yui Hatano by finding out her weakness!! What's my son's is mine!! One day my son brought his girlfriend over, and it was Yui Hatano! The Yui I admire, who I always use for masturbation, was right in front of me! What's more, she even had a lovey-dovey creampie sex with my son! I was so frustrated that I decided to cuckold her and do whatever I wanted.
