Jquery: find any paragraph that is followed by an unordered list, then apply CSS rule

At the moment i have a css rule that applies a padding-bottom:13px; to all paragraphs.
Unfortunately, this gap doesn't look good when an unordered list immediately follows a paragraph.

So, I would like to apply a margin-top:-13px; to the unordered list.

I need jquery code that:

1. Searches inside a div content.
2. In this div content, find any paragraph that is followed by an unordered list, apply margin-top:-10px to the unordered list

I know the Jquery code to find the paragraph and apply css rule goes something like this I think,
$('p').css( "margin-top", "-13px" );


Sample HTML Code

 

<div class="content">
<p>This is the first paragraph</p>
<p>This is the second paragraph</p>

<p>This is a title </p>
<ul>
  <li>the quick brown fox</li>
  <li>jumped over </li>
  <li>the lazy sheep</li>
</ul>

<p>This is another title </p>
<ul>
  <li>the lazy sheep</li>
  <li>jumped over </li>
  <li>the quick brown fox</li>
</ul>
</div>
