Our slave probably has a virus and is therefore now not only a slave but a patient! We have to find a remedy and will check with our big strap-on dicks to see if we find the virus. First we will scan his throat with our dicks, putting them deep into his mouth. The slave gets well-fucked but the virus seems to have hidden somewhere else. So we have no choice other than to fuck our patient hard with our huge cocks in his ass!
