Sphygmomanometer blowjob

[ferro20]

I know it's almost impossible to help me with this request but i wanna try anyway. I'm looking for a porn scene that i saw when a boy in the eighties. Ther was an incredible scene with a girl (maybe a nurse) who was doing a blowjob with an inflatable cuff of a sphygmomanometer to a lucky guy (blowing and pumping, wow!). I can't remember more, i was so young. I've been looking for this for two decades. Maybe someone can help me. Thanks in advance.
