Everytime Kei came down with her hips upon his, Cyrus would let out a muffled grunt of pleasure, but his mind was of mixed emotions. His gaze kept turning from the succubus to the door in a rapid pattern as the steps came closer and closer. He felt the pain of humiliation closing in as the door opened and when it did, he stopped all movement save for his eyeballs. He could tell from looking at the bottom up that it was a girl which might make things much worse. They had a habit of screaming in panic upon gazing at a sight like this and no doubt, her screams would alert the rest of the students as to what was going on.
But then the unexpected happened. Without getting the chance to look the girl right in the eyes, she collapsed to the floor in a heap, obviously overcome by the sight of Kei riding Cyrus like a cowgirl would a horse. That's when he spotted the green hair, the big boobs and the familar flustered look that could belong to only one person, that being Sakuya. Kei had pulled away from the kiss then and the young man, shocked at the scene in front of him did not let out a peep despite the pressure Kei's vagina was putting on his dick. He looked up at Kei who made a remark lacking any kind of concern for Sakuya and replied in turn, "Hey, shouldn't we help her?" And before he could protest further, she was back upon his lips with her own. By now though, the pleasure was becoming too great for Cyrus to try and care any further for Sakuya's plight and once again, the muffled sounds of moaning could be the only thing heard.
A few minutes passed then and Cyrus, by this point, had begun thrusting his hips again, the familiar intensity of an orgasm shooting through his nerves. He hoped that with out a doubt, this would be the last orgasm he would have for awhile and decided to try and make it as intense as possible so as to feed Kei's desires to their fullest. This, of course, required some imaginative thought on his part and he began to think of various things to intensify his orgasm. Boobs, blowjobs, titfucks, anything that would get him to shoot his load with the intensity of a firehose. Finally, after what seemed an eternity, the thoughts did their job and the young man shot his second load into Kei, a loud, muffled moan vibrating both of their mouths. Surely, if she released the kiss now, everyone on earth would probably be able to hear him.
