This occurs when, during anal sex, the lube on the penis and the juices of the receiver combine to form anal residue. This is often white in colour, but can be slightly yellow-brown in colour if inadequate douching has been performed previously to intercourse.
Robin and Ernest had such hot sex last night! But whilst I watched, I noticed there was anal residue on Robin's cock... fuck!
