Several days after the fight with Kokabiel, and a few after Xenovia joined Rias's peerage and moved into the dorm, Alex awoke and immediately noticed two things. The first was that his member was in something warm and moist, the second was that when he opened his eyes the first thing he saw was a panty covered crotch in his face.
It took him half a second to confirm Rias was still asleep next to him, the other half was going through the list of "suspects". After he believed he knew who the "culprit" was, he swiftly removed her last line of defense and enjoyed the meal. She shivered at his touch, and confirmed his suspicions by saying,
"Ara ara, you're rather eager in the mornings, huh alex? Though I'm not one to talk." He didn't answer her, but Akeno didn't seem to mind considering what his mouth was currently doing, and went back to her own "meal". It only took a few minutes before they both finished, he into her mouth, and her onto his face. After taking another minute to clean up, she then turned around and said,
"Ufufu, how about we go even further?" But Alex simply shook his head and replied to her hurt look,
"If we did we're both probably dead." At that moment they both looked to the side and saw the now awake Rias glaring at them.
"Oh don't mind me, just keep doing what you want as if I'm not even here." She said with fury in her voice. Alex sighed, he had told her that he wanted to be accompanied by numerous girls in the future, but apparently this and that are two different things. While they started bickering, Alex quietly slipped away and entered the shower.
After a few minutes Rias joined him and started sulking, until he scrubbed her body for her, inside and out. After the shower he went down to the kitchen, and joined the rest of the residents for breakfast. Rias then announced to everyone,
"As a thanks for the Sitri group, we're going to be cleaning the school pool today for them, and we'll get be the first ones to use it later." As the girls were talking amongst themselves, Alex was thinking to himself, 'First Akeno, then Rias, and now it'll probably Xenovia later. Today's a very "active" day.'
Later they were all cleaning the pool, Kiba was with them, but said that he had something else to do later so he wouldn't be joining them while swimming. Alex suspected training of course. Once they were done cleaning, Rias had Akeno fill it with magic and they all started playing. Rias and Akeno restarted the earlier argument by competing for him to rub sunscreen for them. Asia and Koneko busied themselves by playing around the pool, but they occasionally looked over in interest.
Later Alex said he was going to search for Xenovia, and went into the building. He found her contemplating something, and asked her what was wrong, knowing completely well what was on her mind.
"I'm somewhat lost, the church was everything to me, but now I have nothing. I asked Rias what I should live for, and she told me to love by my own desires." Alex nodded, aware of which direction this was going. She stood and faced him directly,
"Please have a baby with me!" Alex looked surprised, then agreed right before she attacked him with her lips. As she was kissing him, he swiftly released her of her swimsuit, leaving her in the nude. Xenovia looked anxious, as this was her first time, and Alex slid his fingers down her body to stimulate her. She then started moaning as his fingers worked her, and he pushed her towards a wall, and pinned her against it. Instead of resisting though, she wrapped her legs around him for support and she seemed to become even more excited, and was soon ready to receive him.
She gasped at the foreign object entering her, before her cheery was popped. As with Rias he gave her a minute to adjust to the pain, before he started thrusting. Soon the entire room was filled with the sounds of their moans as they became engulfed in pleasure. After a while they both finally reached their limits, and he did as she originally wanted and sprayed his seed inside of her.
As they both came down from their high, the door burst open and Rias and Akeno appeared. He didn't know who was the most pissed, Rias who caught him screwing another woman, or Akeno who wasn't able to that morning. He then had to endure them both ranting at him, until he pacified Akeno by promising to be with her soon, and Rias that night. Asia and Koneko where outside still, and were completely ignorant of the events that just took place.
