ABALONE KISS presents a new netorare AVG under its its sublabel, ABALONE KISS * CORE.

Experience the story from two perspectives:
"I", the first-person protagonist, and Rin, my beautiful street-tough girlfriend.
Rin protects me from a gang of guys by getting mercilessly f*cked.
When I realize she didn't betray she... she sacrificed herself...

I can barely live with the regret.
Her tears, her words, her cruel behavior, it was all to SAVE me!

* Hardcore cuckoldry
