I gave you a 5* rating. It is a well rounded story. The sex descriptions hit the right tone and are a quite arousing.
Two minor points:
1. I think a little more description of Dave and how he knew Jenny well enough to discuss Lily would improve the scene setting; and
2. To me it would have been hotter if Dave had used Lily's name throughout. Using 'baby' jarred and felt off. In everything else Dave shows consideration for Lily.
