Alex slowly walked towards the gathered girls while removing his own clothes, and taking in their attire, or lack of. Akeno was in a see-through miko outfit that was short enough that the lack of underwear was apparent. Xenovia was looking somewhat awkward in a bondage outfit similar to her combat gear, except the crotch and breasts were completely exposed. Rosswiesse was beat red while simply wearing sexy see-through underwear. Kiryuu was wearing her school uniform, but was missing her skirt and panties; instead she had a couple devices strapped to her legs, with cords running up to her crotch and possibly her ass.
He then turned his attention to Rias and Asia, who seemed to be presenting themselves as a combination in naked aprons. The other combo was Koneko and Ravel in sexy maid outfits, who Alex looked at weirdly since he said he wasn't going to touch them yet. Rias noticed his looks and explained,
"We already had to wait until Irina left to report to heaven about something, we can't just kick them out for the day or have them locked in their rooms. They'll be present but not actually participating with you." The two looked sad her words, but Alex nodded in confirmation. He also noticed a suspicious box off to the side but didn't say anything about it. He then turned his attention to the first girl he was after, causing Rosswiesse to turned even redder. He moved towards her and grabbed her by the waist, and pulled her close.
He started kissing her while his hands ran along her ass, before he slipped them to the sides of her see-through panties, and pulled the strings on them. When the small cloth fell to the floor she stiffened, and Alex lifted her and sat her on the counter. He slipped his hands between her legs and started playing with her wet slit, earning him a few moans. He used his other hand to remove her sexy bra, leaving her the first to be completely nude.
Her left nipple then disappeared into his mouth, where he felt it growing stiffer by the second. It only took a few more moments before she was ready for penetration. In one swift movement he entered her, causing the biggest moan yet.
"AAAHHHHHHHH!" And he started to piston inside of her. Her legs wrapped around him as she felt the pleasure. It only took moments before he managed to cream pie her, leaving Rosswiesse to lay back on the counter with his sperm flowing out of her. He then turned his attention to the other girls, and was amazed at what he saw. Rias was sitting on a chair with Asia's head buried in her crotch, Ravel and Koneko were entertaining each other with their hands, and Akeno was playing with Xenovia with a toy. He then turned his attention to the only one without a partner, Kiryuu. She smiled when she saw him looking at her and strutted forward.
"You know senior, I mostly wanted someone to make my first time memorable, but you completely broke me. How do you plan to take responsibility for this?" She smirked, while he smiled and leaned over to whisper in her ear,
"Turn around and bend over, and I'll show you." She shuddered at his words, and swiftly did as he said, spreading herself open as she did so. Alex saw that his guess was correct, and saw one cord entered her soaking slit, and the other led into her wrinkled anus. He then teasingly tugged on both cords, but didn't remove them. Finally with an audible,
POP
A small vibrating device popped out of her, and Alex aimed himself to enter the same hole. She shuddered at his prodding, until she felt his entire length fill her ass.
"YYYEEEEEEESSSSSSSSS!!!!!!"
She screamed in joy, as her ass was pounded with a fury. The other girls turned to look at her, as they were curious about how anal felt so good. Alex was enjoying the unusual tightness as well as the vibrating sensation from the other toy, as kiryuu's ass gripped his rod like a vice. It wasn't long until he exploded into her as well, with Kiryuu climaxing as she felt the burning sensation in her ass. Once Alex removed himself from her, Kiryuu immediately turned around and took his length into her mouth, relishing the taste of her own ass.
Once she had cleaned him, Alex turned to the next girl, while Kiryuu went and started eating out Rosswiesse. He turned to the combination of Xenovia and Akeno, and made his way over to them. When Akeno saw him she smiled, and pushed him down. After that she mounted him and rode him cowgirl style, while Xenovia positioned herself above his face, and sat. He proceeded to eat out Xenovia while Akeno rode him, taking as much of him into her as possible.
The two girls were panting up a storm, before they leaned forward and started making out above him, while playing with each other's tits. Alex was unaware of this, as his face was still buried in Xenovia's ass and he continued eating her out. It didn't take long until Akeno as well got her fill of his sperm, and removed herself from his still standing rod. Xenovia stood as well, and Alex followed her, before bringing her into his embrace and entered her while they were still standing.
The two were screwing while still standing, and Alex watched as Akeno got out something from the box. He paled as he saw her put on a strap on, and started covering the toy with lubricant. She snuck up behind Xenovia, and Alex slowed his movements as Akeno started penetrating Xenovia's ass.
"AAAAAHHHHHHHHHHHH!!!!!"
The blue haired girl screamed as she was penetrated in both holes at once. She didn't reject it though, and raised her legs to wrap around Alex, leaving her only support the two rods in her. As she continued screaming Kiryuu looked up from Rosswiesse's crotch, and seemed to be jealous of the double penetration Xenovia received. Soon Xenovia got her fill as well, as she also experienced her first orgasm from having her ass penetrated. As he pulled out from her, the white fluid followed and both Xenovia and Akeno had it running down their legs. They then got onto their knees and started cleaning him together.
Once they finished Alex turned to the last two to receive his attention, while Koneko and Ravel had removed each other's clothes and we're going full on with each other, looking at him as they did so. He instead turned to Rias and Asia, who had removed their aprons and were pleasing each other. Alex then moved them so that Rias was pinning Asia down with their legs spread. He then rubbed his length between the twos, effectively teasing both of them.
It didn't take long until his member slipped into Rias's slit, and he started to pound her while she kissed Asia beneath her. After a few thrusts, he pulled out however and immediately plunged himself into Asia right below her. After thrusting a few times into her he did the same and reentered Rias. In this manner he alternated between the two, until both were filled by him. They both lay there, his seed flowing out of both of them, and he suddenly heard his name being called.
"Alex, you aren't done with us yet, are you?" He turned and saw the rest of the girls, ready for the next round. They then continued for many, many hours that day.
