This hentai is the worst type of NTR, the willing kind. Do not read if you cannot stomach the cheating and corruption of the GF
and how she supposedly still loves the weak BF even though she is cheating behind back and laughing at his sexual inadequacies. She texted the guy she hates to come over while having sex with her boyfriend because the boyfriend has a small dick and leaves her unsatisfied; throws out the boyfriend and spends the rest of the long summer break with the big dick dude! The anime is worse as it shows it in better detail!
It took me the better part of week to recover from this crap and I usually do not mind NTR.
Your right I was just looking for aot until I saw this. I reared it and it was absolutely horrible. Who would cheat on their boyfriend that has been loyal for so much time. That woman is a bitch and so is the ugly ass dude. The boyfriend deserves better.
