Neo ignored Niwa's emotions and started rocking his hips back and forth, making his shaft slide in and out of her mouth.
There was nothing to worry about since Niwa could take it all in without any problem.
The technique Neo used was among the first few beginner-level manuals from the Grand Lust Sovereign's inheritance.
The first five movements focused on a woman's orgasm, the following five movements focused on the orgasm build-up, and the latter five on making a woman get comfortable with the cultivator.
There were many more, but in the first volume of the manual, only fifteen movements, along with an additional five that spoke about pure dual cultivation, were present.
Neo couldn't find anything other than that in his mind, as his Master hadn't shared it with him.
Lith didn't do so because he didn't have access to it. The inheritance he received was not complete. He would get the rest only if the curse was broken.
