Too good to stop: Requested by Anonymous

If 12 year old  Richard thought finding himself in his female neighbours body whilst she was bent over as her boyfriend took her roughly from behind was bad enough.

If only he knew what was to come.

If only he knew inside the woman's boyfriend's body was his 15 year old sister who was intoxicated on male hormones and would not stop screwing this woman until she had filled her with her seed.

Which in the end led to his other bit of bad news as he had not just been screwed by his sister in a male body as according to His gynecologist he was pregnant with her child.

Which wasn't as bad as it sounded as now they were no longer biologically related.

But he had no intention of settling down with her and starting the perfect family as in the end they were still brother and sister despite what the great shift had done to them.
