He licks my sweaty feet by english conversation

I was wearing boots all day today, so my feet were really wet and sweaty after this day. I enjoy relaxing when a colleague first sniff and licks my feet in wet socks, then slowly takes off the socks and licks my sweaty feet and cleans my tired soles with his tongue. We are talking by this and i teach him english, so we have english conversation, while he licks my bare soles. Look how I enjoy this lesson and taking care of my sweaty feet.
