Best of Both

After that, Twilight developed a slight addiction. The experience she had with both versions of Flash was a level of pleasure that she doubted could ever be replicated in any other way, so she began having sex with both of them at the same time via the portal continuously, which neither of them really complained about and though neither of them still got to enjoy her pussy, they were perfectly happy to violate and defile her mouth and ass so long as they made sure she suffered from the perverse enjoyment she got from handing her safety over to them. As time went on things only got more and more depraved and Twilight never once thought it was going too far, miraculously, neither Flash was aware of the other, they still hadn't discovered the truth behind Twilight's penchant for performing sex acts at the portal. It was incredible that the portal did such a good job of hiding the fact that while she was sucking she was also receiving a fucking, she couldn't imagine what kind of situation she would be in if they did know about each other.

Eventually, the sex with Flash Sentry and... Flash Sentry, pretty much became a routine for her, as important as any royal duty. She'd get up in the morning, check her list of royal duties with Spike, talk to dignitaries, overlook political debates, do routine visits to certain events, visit the portal to have Flash and Flash annihilate her sexually, then top it all off by going to bed.

The End
