What is Johnny-cum-lately?
1.
A sexual act involving a facial from the doggy style position. A man wishes to give his partner a facial but cannot get to her face in time. He cums into his own hand and then smears it in her face, hence cumming lately and acheiving the desired result.
"That ass looked so fine I came too quick. Couldn't give her a real facial so had to settle for the Johnny-cum-lately"
