Short Story (8964 words).
Cassie finds out her sex-buddy friend Eric sometimes takes part in group sex. He has a friend, Katie, who likes to have sex with four or five men at once. Cassie is intrigued, and asks if she can watch, and Eric says that nobody involved will mind. They won’t mind, Cassie thinks, because they want her to join in. She goes along anyway, and finds herself wanting to join in, and that idea is both sexy and terrifying at the same time. She isn’t even sure she could have sex with five men in a row, but she secretly wants to try. Slowly, over several visits, while everyone is unspeakably kind to her, she talks herself into doing it. And along the way she starts to fall for another man involved in the orgies, Craig.
