When Alex woke the next morning the first thing he did was untangle himself from the pile of bodies and take a shower. It wasn't until he had the water running on him that he looked at the notification he received the night before. He had been about to sleep when he got it so he didn't see what it was.
""Endless sexual stamina"? Do I laugh or cry at this?" He asked in frustration. Both Lauren and Ddraig were laughing their asses of, if they even had any. Alex then thought to Ddraig, 'why are laughing? Isn't it almost like a return of the oppai dragon?' After a few moments Ddraig calmed down and said,
As the next couple days went by leading up to the conference, Rias and the other two grew concerned. They had noticed that even though all three of them were with Alex every night, he wasn't getting tired after pleasing all of them. They then conspired to try his limits out, to their own demise.
"Alex, all there is to do tomorrow is training with Gasper, tonight go for as long as you want." Rias said with a seductive tone with Akeno and Xenovia flanking her. Alex took them up on their offer, and didn't even notice how long he was screwing them until the sun started glaring in his eyes, signaling morning. It wasn't till this point that he looked at the three women, and saw the devastation he caused. Once he stopped to look out the window, they all started passing out due to exhaustion. All Alex felt was sleepiness from not sleeping the whole night. He suddenly felt sorry for them after he lost control, and cleaned them up before tucking them in and going down to breakfast.
"Where's everyone, breakfast is almost ready and we have training to go to." Asia asked him when he got to the kitchen, with Koneko watching him. Alex grew anxious before finally admitting,
"They're all asleep after I lost control last night." Both of the widened their eyes at his words and Asia turned beet red, while Koneko muttered,
"Beast" Alex couldn't help but think to himself, 'but they told me to, I only did as they asked.' But kept quiet since he didn't want to mention his 'endless sexual stamina' skill to anyone. After an awkward breakfast, the three of them left to meet Kiba and Gasper at the old school building. To Alex's surprise, the Sitri peerage also joined them for a rare joint training. Sona looked around though and asked,
"Wheres Rias, Akeno, and the new knight, Xenovia?" Alex looked uncomfortable until Koneko answered for him,
"This beast lost control last night and they're sleeping it off." Kiba and Gasper went wide eyed at her words, and the entire Sitri peerage joined them, but all the females almost had an interested look in their eyes. The only exceptions were Tsubaki, and Sona who went red at the thought, and was only made worse when Alex winked at her. Saji also noticed this though and almost blew up at Alex.
They then trained with both groups, and Alex surpised everyone when he suggested using absorption line on Gasper to control his powers. Saji wanted to argue, but was prevented from doing so after Sona told him to listen. The training was uneventful after and the females all returned to the dorms for dinner. Saji decided to continue training because he wasn't as welcome at the dorm, and he wanted to get stronger than Alex.
After having Asia cook dinner, they were all sitting around talking when Rias, Akeno, and Xenovia all came downstairs. They were about to greet them, but froze at the sight. All three were walking bow legged, and seemed to have trouble standing. Alex once again felt guilty and went to help, only to have them say,
"We asked for to to keep going until you wanted to stop. I can only be blamed for my lack of wariness at your capabilities." They then ate a little, and slowly went back upstairs to go back to sleep. Alex realized that he would probably be sleeping alone tonight for the first time in a while. Because he was watching the three leave with concern, he didn't notice the almost predatory look in the Sitri peerage eyes. Sona face palmed at her members actions.
What Alex also didn't know, was that his actions that day helped Rias make a decision. She had learned the hard way that she would most likely never be enough for Alex, and that she might have to be a little proactive in building his harem. She decided this because her body might break down if she continued trying to keep him to herself. Akeno already accepted being the mistress, and Xenovia was mostly trying for a baby, so they didn't mind more women as long as he paid them attention.
