So it was all about balls? (r18 I guess?)

"So, when your balls hurt, you should hurry up and let me make them feel better, m'kay?" 

Fay's embrace over my head only tightened. And with her stomach pressing tightly against my lips, I couldn't utter even a single word… Putting the validity of Fay's question in doubt. 

After all, why would she ask me anything if the first thing she did after was preventing me from speaking up?

Still, while my thoughts raced to figure out the situation and how I was supposed to behave, Fay's embrace grew only tighter… Only for the girl to slowly start moving forward. 

Bit by bit, my face slid down her waist, through her upper and then lower abdomen, all the way to the point where her shirt ended. 

But Fay continued to slowly move forward while maintaining perfect control of her grasp over my head, keeping it loose enough to allow my face to move but tight enough to stop me from escaping.
