When one of the masked doctors told him to suck the other's cock, Mark's eyes went wide. He swore he misheard, but when the doctor repeated the request, Mark's cock visibly shot up, as if volunteering without saying a word.
As Mark began to suck, he looked up at the unnamed man. He worked the shaft with his lips, feeling his own swell up and reach full strength. The tall doctor clearly liked it, causing Mark to swallow copious amounts of his precum.
Sitting at a computer and watching intently, the doctor ordered his colleague to remove his clothes and prepare to be bred by the young man. Mark couldn't believe what he heard, but before he could make sense of it, the tall man removed all his clothes, got up on the exam table, and presented his ass to be fucked.
