I've noticed that there are a number of models that have a degree of elasticity to their asses and can do dap/tap fairly easily.
examples would be Natasha Teen, Proxy Paige, Isabella Clarke.

Can anyone name other models with this talent?

Anna de Ville comes to mind.

Linda Sweet, Rebecca Black, Kira Thorn, Susana Melo, Lyna Cypher, Madison Lush, Monika Wild, Susan Ayn.
