The day you were consummated!?

Suddenly you have a crazy idea. You wonder if it would be possible to father yourself into this world by having sex with your mother the day you were consummated.
Now not everyone knows that date even though it is so important, but since your father used to brag about it so much you could never forget it.

You travel back to a beach in Hawaii where you spot your mother as a young adult. She's tanned, large breasted and beautiful with long brown hair. She's wearing a pink bikini and seems to be waiting for someone on this isolated spot on the beach. She lays down on her belly on a towel and starts to unhook her top.

You know the story. Your father arrives late and they have sex on the beach.... ok it's not a great story but it was for him.

So how should you do this? You could just freeze time and fuck her. Truth is no matter what you do it'll be **** so why not just make it really really fun ****!
Sure, you could attempt to woo her but you don't have time for that....oh wait.
