Tit Job on LetMeJizz
Search this and you might expect before-and-after surgery shots, when it actually means a cock worked up and down inside a slicked pair of tits until it erupts. The breasts do the stroking, squeezed tight around the shaft rather than any hand or mouth. Bigger, heavier sets get the spotlight because they swallow more of the cock and make the finish messier.
