I just had a session with Kinky Little Nikki, she used her rope tying experience to lace up my balls and shaft in such a way that each ball was cradled (zero discomfort) and pulled up to expose the underside. She used a tennis shoe lace, the effect was raging hard on that stayed hard throughout the playtime... she did say that she would need to release the pressure about every 15 min or risk damage from lack of blood flow....
Nikki knows how to please in various ways
