What starts as a night of lust ends as an elopement of love.
Interesting backstory to why the mom went for Sam that night in question, and that doesn't interfere with their moment. Her reactions play out plausibly, where she tries to avoid it but it infuriates her when he leaves--but they still yearn for each other.
Showing the new "beau" as a jackass is quick yet more than satisfactory, as is him proving her desire for him by taking her in both senses. I can justify the sudden ending as satisfying enough--especially when she shows Jake what she REALLY thinks of him.
About the only weak link is that Sam seems a carryover from another story, and while he's hinted at being calculating, we don't really see Sam "destroy" Jake as he thinks in his mind, since he elopes with his mom and thus avoids the conflict (whereas Jake seemed the real dislikeable turd and did say what he might do). While Sam plays along, it's a very short time and thus doesn't really allow us to gauge if Sam can execute a cunning and devious plan to really raze Jake to the ground.
The author leaves the story open-ended so it's possible they could do just about anything--including having kids together--and another installment could show us how Sam eludes and counters Jake's efforts to hurt his mom and/or him. I personally would like to see it continued if the author's so inclined, just so we could see how their relationship deepens, how they face struggle and how they might face possible retaliation, since the conflict would really test if this is love or lust. Still a solid story, worth the read.
