by happenstance
Good setting. Poor narration. Characters got wasted. Seems to be written in a hurry! Need to rewrite when u have more time. Got style, could do better.
Sorry buddy but that was just poorly written and not even slightly erotic. Keep trying though! I don't see much point in writing a sequel to this but maybe if you get in contact with a decent editor and rewrite or start a new story.
I hope in chapter 2 there is reluctance from mom and she struggles within herself about doing her son but desire wins.
Son needs his Mother but before that happens his Aunt must get him ready for the big show. The writer must work on developing the characters better. Mother's desire must be prepared by Aunt first. Aunt has to get herself dressed in special lingerie for her nephew. The first fuck can be viewed by Mom hiding in the closet masturbating herself watching the act being fucked. The possibility of a great story needs more work here.
There are holes in the story that could be overlooked if there weren't so many:
1.Why didn't anyone pack a bathing suit for a stay at the lake?
2. Is this a private lake or does everyone swim in their panties and undies?
3. A normal Mom doesn't go around in her panties and bra in front of her son, unless they are very open about nudity or they are already fucking each other. Not explained
4."went behind the rocks, where I took off my undies and masturbated"; hog wash...
Why go on with the list, please let someone proof read your story before submitting.
Nice start. I like character and plot development. For a short story is this okay.
