Celadon knew what was coming next. Sure enough, two of Dr Gill's lubricated fingers entered his hole, stretching, thrusting, probing the walnut-sized gland hidden inside him that filled his groin with a warm spreading pleasure. Celadon sighed and sank blissfully into the padded surface of the bench. The dildo in his mouth pressed pleasantly against his tongue and throat. His master's massage of his prostate was steady and sure. He began to moan.
As the massage continued, the pleasure inside Celadon continued to grow, until he felt like he could burst. All the pent up desire of the past week welled up in him, and he began to buck and strain against his restraints.
"Steady now." Dr Gill's voice was gentle but stern, reminding Celadon of the conduct expected of him. His master was not one for excessive displays of emotion. Celadon was to maintain stoic composure wherever possible.
Celadon whined as he fought to regain control. Dr Gill began to massage his testicles, squeezing and stroking the delicate package with one hand while continuing his relentless milking with the other.
This new assault on his senses only increased Celadon's struggle to compose himself. Dr Gill's handling of his testicles felt absolutely heavenly, and he panted and moaned helplessly around his gag despite his best efforts, fully consumed by desperate desire. As the milking of his prostate continued, he felt a familiar weakness in his legs, and they began to buckle and shake uncontrollably.
Upon seeing this, Dr Gill began to gently spank Celadon's testicles, a steady tap, tap, tap that made his toes curl and his body stiffen as he let out a guttural groan. This was his weak spot. There was pain, yes, but a good pain that made him crave more, and a pleasure deep within him that grew with each strike. If this continued, it wouldn't be long now before he came. Ever since Dr Gill had discovered that Celadon could orgasm in this way, he had scarcely touched his penis, except to clean it. Celadon missed the pleasure of it, but he loved the submissive state the denial induced in him. Part of him hoped to never be touched there again, as much as the rest of him craved it.
Sure enough, Dr Gill's handling of Celadon's testicles and prostate rapidly overwhelmed him and he came with a strangled cry, hips spasming as he spurted onto the floor below. He continued to moan and twitch as Dr Gill withdrew his fingers.
"You may come in, girls," called Dr Gill, and Clover and Fern stepped into the room once more. He thanked Clover graciously as she handed him a small stack of hot damp terry washcloths on a silver tray, while Fern set to work mopping up Celadon's emissions spattered on the floor.
Dr Gill wiped his hands with a washcloth, then methodically set about the task of cleaning his boy. Celadon winced at the rough texture once again being worked over his sensitive post-orgasmic head and delicate pink hole. Once finished, he locked Celadon's belt back in place, pulled his trousers back up, and released him from his restraints.
Emerging from his post-orgasmic daze, Celadon flexed his jaw and body, slightly stiff from being restrained. Dr Gill pulled him into another kiss, softer this time. Tender. Celadon closed his eyes. He was in heaven. Gently, Dr Gill stroked his hair.
"Good boy."
