Her cheating experiment NTR: My girlfriend was having sex with her super-strong best friend like a monkey, and had creampie sex.

He doesn't like women who cheat, so he suggests his best friend try to experiment with infidelity by saying that his girlfriend, who he just dates, is a devoted woman, or that he will try to set a trap. The rule was that they exchange contact information and if they came to the house, they weren't allowed to leave... but they fell in love with Akari, who shows off her innocent cuteness, and Akari responded, not only did she go beyond the line, but even ended up cumming inside her... The two were caught in a ignorance from a mere experiment, and they cum inside her many times...
