Nurse Cherry is here to take care of you today. Your contributions to science are greatly appreciated and I will do anything for the cause. What cause is that? Why checking to see how hard I can make you. How well you respond to oral stimulation. How much stamina your balls and cock have. Are you able to hold off cumming with my lips wrapped around your dick, using my tongue to lick your hard shaft up, down and around? How about as I'm standing over you, pulling off my red thong and sliding my tiny twat onto your cock? Just how much and how deep will you cum in my tight, wet pussy as I ride you? All in the name of SCIENCE!
