Four days, that's how long lasted the great love session of Lucien and his Maid Harem. For them, it was so good that it felt like a few hours of fun, but for the group that was training for the competition, it felt like a whole month.
As Lucien's wives missed him so much after their long time apart, he had to make up for them with a lot of individual time, and so he didn't rest during those four days.
By the end of the last day, all the girls had been satisfied, but the first ones that got his attention were already wanting more love. Lucien feels like they're insatiable, but so is he because even after four days of sex, he's still hard and horny.
Please them pleases him, and it makes everyone stronger, so he would have no problem keeping it up until everyone reached the peak of the power in the universe. But there are more people who require his attention out of his bed.
