A beautiful and mysterious well endowed woman... Her sweet words like nectar to my ears.
My heart and body slowly subverted by her pampering paradise.
"You're such a good boy." she says, positively reassuring and praising me... No matter WHAT I do.

After the protagonist was dumped by his girlfriend he happened across a beautiful woman at a shrine.
She praises and positively reassures him... filling the hole left in his wounded heart.
Every day after returning home from work Mahiro embraces the woman, indulging in her body... and the sweet words of nectar that flow from her mouth.
Having grown dependent on her... both physically and mentally... Mahiro begins his descent into madness.
