((I've actually been toying with the idea, but never got around to asking how you'd feel about it. Since you're willing, sure, I'll have the boys join in and perhaps even the teacher as well.^_^))
Kira continued to pleasure her friend, but jumping lightly when she suddenly felt a hand rubbing her panty covered ass. Taking a moment to glance back over her shoulder, she saw one of the boys leaning down behind her, rubbing her firm ass after pushing her skirt up around her waist. Then......she just went back to pleasuring Orihime, letting him do what he wanted. Seeing how willing she was, a few more guys came over and they too started to fondle her perfect ass, reaching between her legs to rub her pussy as well.
Orihime wasn't left alone either. Another group of boys come up behind her and didn't hesitate to reach around her and maul those massive tits of hers. Any protests she might have were quickly silenced when one of the boys turned her head to the side and immediately captured her lips in a kiss, his tongue darting out to invade her mouth.
The rather attractive busty female teacher they had wasn't spared the sex frenzy either. Three boys had her pinned up against the black board, fondling every inch of her through her attractive business suit. Though, she wasn't quite as willing as Kira, as she tried to push the boys away, but failed as they tore open her blouse and quickly freed her large breasts from her bra. Bouncing free, both breasts were immediately snatched in the mouths of two boys, each suck and licking her nipple. The entire class had degenerated into an orgy pretty much. Kira had a group fondling her back side and pussy, Orihime had a group manhandling her breasts and even the attractive teacher had her own group of boys, who now had her mostly stripped and bent over her desk, preparing to take her from behind, with her apparently willing now, as they would occasionally smack her ass, which would make her moan and ask for more...........It was quite the scene. It would seem Kira usual molesting had had quite the effect on the entire class. Thankfully, the door was shut, so none of the other students in other classes had any idea what was going on, but it would no doubt spread around school and be legendary for years to come.
Kira and Orihime would certainly get major popularity boosts due to this.
