Head back to Michael.

From Create Your Own Story

You fart out the last of his cum, the load was very big. You then wipe the cum from the outside of your ass, then wipe it off from your mouth and pull up your thong and panties before leaving the bathroom stall. You make your way back over to the table where Michael is already sat down, "The waitress came over but I wasn't sure what you wanted so I told her to come back in a little while." Said Michael with a hint of happiness. "Sorry I took so long, Have you been waiting for long?" You say apologetically, "actually I just game back from the toilets about 2 minutes ago." Said Michael.

You glance at Michaels shoes under the table and your heart almost stopped. Grey and White sneakers, you stumble to find the words "those... Those are nice sneakers hun. Stand up so I can get a better look at them." You are filled with worry. Michael stands up "Thanks mom, I like them too." Michael says happily. You scan the restraunt for anyone else with those same shoes, nothing. "Argh these damn jeans." Michael complained, "I'm missing the top button, because they got so old and broke." Michael confirmed your fears.

You replay the whole kinky encounter in the bathroom stalls, now knowing that the 'man' you were getting stuffed in the ass by, was your son.
