The sister-in-law, frustrated by her husband's sexual insatiable desires and somewhat delirious, called to say she wanted to meet.

I have a good relationship with my uncle's wife and we keep in touch frequently. One day, she complained that her husband (my uncle) couldn't satisfy her lately and asked if we could meet on a day when he was away on a business trip. Since she needed an opportunity to release her pent-up sexual desire, I invited my friend and my uncle's wife to a hotel for a sex party. Although it was a bit awkward, for my uncle's wife's sake, we ejaculated again and again until she was satisfied, aiming to surpass her previous record for ejaculation.
