Lick our cum feet, slave!

My girlfriend and I had an application from a slave who wanted to be of service to us. So we invited him and the first thing he was allowed to do was lick our feet clean. After he had done his first job, he was then allowed to lick out my girlfriend's freshly inseminated cunt. When he had also done this job to our satisfaction, he got a footjob from us as a reward and was then allowed to lick his own cum off our feet. The boy has potential and we are already thinking about where else we can use him. Do you have any ideas? Then please send it to us
