cumming while trying not to

This is inspired in part by a very intriguing comic story I saw in a porn magazine years ago, the plot was that two female succubi needed to conceive the antichrist with some human sperm, not in their bodies but in another, so they just grabbed a dweeb off the street and, true to their name, sucked him off to collect the sperm. He was aware of what they were doing and why, and trying very hard not to cum, but they had him tied up and their buxom bodies and earnest mouths were no match for his resistance, so he held back as long as he could and then finally ejaculated, knowing this would end the world. To me that's a powerful scenario, and when I am getting sucked off I usually try to delay my orgasm to make it better, but always of course wanting it to happen eventually. I wonder if anyone else has been able to explore similar scenarios, either in reality or in a play scene, with a man trying not to cum, or even disdaining the blowjob itself, while the woman is earnestly doing all she can to bring him to orgasm. Perhaps because she wants to be his girlfriend or win a bet or something like that, while he is reluctant to help but of course eventually ends up cumming all the more powerfully after resisting it.
