Really REALLY like where this is going. Two people who love each other very very much and are open with their kinks and know what turns them on, and are pleased to experiment with exploring those kinks. The writing is done really well to explore these characters.
Good NTS scenarios like this are hard to find, and I mostly just end up finding the same old boring NTR scenarios instead. Keep up the good work, can't wait to play the final product in the future!
