Laughter and Desire (tickling erotica)

Briana's friend Heather has a male roommate named D.J. who seems nice but there's something a little strange about him. There's always laughter coming from his room.
When Briana needs help with a paper she learns exactly why there's so much laughter going on in that room. And she's starting to crave it. When asks D.J. for more help, she gets a ticklish experience that helps her grade and her body.
