Laura wondered what had awoken her until she heard it.

She knew what and who it was; instinctively her hand clasped her mouth, hoping her gasp wouldn’t give her away.

The sounds are coming from her sister's bedroom.

No doubt her sister, Sara, and her brother-in-law, Ted, were FUCKING hard.

Guilty that they had let her stay, and she was behaving like a seedy pervert listening in.

But in the same breath, she felt a pang of envy. Sara's moans sounded like she was having a great time.

Who would have thought that Sara's boring husband, Ted, was a stud?
