Push the doctors balls into Andy

I wrapped my hand around the doctors thick member from under his ball sack, his large heavy balls tight and bulging. "Let me wrap that!" said the doctor, reaching for a leather cock strap. He pulled out of Andy's hole and took his cock out of my hand, wrapping the belt around the base tightly. His cock and balls were turning purple now as the leather restricted the blood and made streams of precum flow out of his tip. The muscles were solid and his shaft was vertical, waving in the air from its base, his balls firmly strapped into place. "Let's give him what he wants!" said the doctor, moving back into position between his opened thighs. I took his solid cock and balls in my hand and pushed his inflated glans into Andy again, the doctor thrusting slowing forward up to his balls. "Poppers again please nurse." said the doctor and he undid the bottle and Andy took a large deep breath, his wet gash quivering again, opening up as the doctors balls pressed harder, enveloping the round globes and swallowing all of his hot rigid tools, my hand was redundant now. The doctor completely disappeared inside Andy and his lips closed around the base of his dick. "Yeahhh!... cried Andy. "Feels so good!" The doctor smiled as Andy wriggled slightly, the nurse had his own massive erection in his hand and was moving up and down and wiping it over Andy's mouth, stifling his moaning. The doctor bend his legs and I could see that his anus was also quite open and in need of attention. I grabbed the bottle of lube and poured it over my hand, placing a finger against his juicy man cunt.
