The clinic is filled with the sounds of wet, sucking noises and the doctor's grunts. He's on his knees, his face buried in the black twink's crotch, his tongue lapping at the pre-cum leaking from the boy's slit. The twink moans, his hands fisting the doctor's hair, pushing his face deeper into his groin. The doctor obliges, swallowing the twink's cock whole, his nose burying into the boy's trimmed pubes. He pulls back, strings of saliva and pre-cum stretching between his lips and the twink's cock, "You're ready for your injection," he says, lubing up his fingers with the boy's juices, pushing them into his tight, eager hole.
