Bisexual Big-Dick Boy's Extreme Sensitive Nipple Conditioning Training

After the previous few training sessions, the physical condition and state of the bisexual big-dick boy has been mastered about 70-80%. We can finally proceed with more intense training! This training mainly targets the nipples, I want to train him so that he can reach ejaculation just by playing with his nipples.

This boy's nipples are very sensitive, just lightly playing with them will elicit a strong reaction from him, unfortunately it's still a bit short of ejaculation! Using this sensitive point, I stack the pleasure progressively, keeping him in an erect and excited state, and repeatedly switching between teasing sensitive areas (nipples) and overly stimulating plays, even when he enters "sage mode" after ejaculation, I can still perform glans torture! For any "conditioning" training, one must be sufficiently clear about the subject's physical condition and state. It is recommended that bondage friends can have more contact and understanding with the person they want to train, so as to more efficiently achieve the training goals!
