You can do that with custom show (Slide Show > Custom Shows).
In the custom show, add the slides you want to loop.
Then, create an action button. Go to the action setting and have it
hyperlink to the custom show. Put a checkmark to show and return.
Next, click Slide Show > Set up show.
Put a checkmark to Loop continuously until esc.
Also, select all the slides that are in the custom show, right click and
select hide slides.
Now, when you press esc in the custom show, you will return to the slide
with action button. Mouse click on it will bring you to the rest of the
presentation.
