My surrogate slave is no longer my surrogate slave but officially my property feet pampering after sports

My rental slave is no longer my rental slave but officially my property. He is still used for other purposes and I don't want to have him around me 24/7, but the first decision was that he no longer has to hide behind a mask. I put him in the small cage before sport, so not his tail, which is in there anyway, but him so that he can really look forward to me.

When I came back from sports I let him out of his cage and he was allowed to lick my sweaty feet intensively, massage them and take them completely in his mouth
