My sister and I were half way through a road trip when we stopped at a hotel where we had reserved a two room suite. Because of flooding in the town our suite was given to a flooded out family, Shelby and I had to do with one bed and a fold out sofa bed.
How a brother lusted after and fell in love with his little sister, only to find out years later that she lusted and loved him too. Now that they are living together, she gathers a harem for him to enjoy. Life is good.
The surprise reunion with Marti (See A MILF Man Lisa) reignites their short-lived affair of three years ago when he gleefully gave a freshly divorced Marti his virginity. But their plans for a weekend together go awry when Marti's incredibly stacked and slightly slutty sister shows up unexpectedly.
This is narratively a continuation of the story 'Lisa' in the 'Erotic Future' universe. However as I was writing these chapters I realised that I was almost writing a Naked In School (NIS) story but for a group dynamic. NIS is one of my favourite universes/collections and if you like Lisa (or not) you should check it out.
