A post elsewhere indirectly reminded me of a film ' Mandingo' where the title character fucks this tough gang lady. She prides herself on challenges where the guys will always cum before she does ( she never loses and never cums herself)
Mandingo fucks her long and hard and leaves her spreadeagled, exhausted and her juices flowing as he literally fucked the her into a state of orgasmic submission.
I actually witnessed that kind of action when enjoying a threesome with a girlfriend and another guy . I had fucked her first but barely got her juices flowing he seemingly gave her an orgasm within a few strokes with his massively bigger cock. ( my penis is tiny and I had never even come close to giving her an O with it)
He had terrific stamina and could only guess how many times she came. When he finally finished she just lay there almost comatose and a combo,of her juices and his cum seeped out of her pussy creating a huge damp spot on the sheets.
