Megan was awakened by a muffled sound of giggling. The room lights were off, and the room was lit by dim twilight from the window. Her eyes opened, and she realized that there was light under the door between her room and Doug's.
She heard it again--a woman's giggle coming from the door. She got up and walked over to the door and listened. There was soft talking on the other side. A woman's voice, and a man's, too muffled to make out the words. She reached for the knob--it was unlocked, Doug and her had been going back and forth between their rooms for the whole trip.
She looked down at herself. She was wearing one of Megan's slinkier nightgown, in anticipate of Doug's return from his meeting. Should she investigate? Should she put on something more modest?
She then heard louder laughing, followed by softer moaning in the woman's voice. She turned the knob, and slowly opened the door.
Megan had known what she would find, but hadn't admitted to herself. Sue! and Doug! Sue was undressed down to her panties. Doug's shirt was off. Sue's head was down in Doug's lap. Eww! Gross!! She was sucking on his penis, something that Megan hadn't been able to bring herself to do.
"Hey babe!" Doug said in his typical confident, cocksure manner. "Come over here...Let's have a party together."
Megan blanched and froze. She pulled her head back and slammed and locked the door, and dissolved into bitter tears as she threw herself on her bed. What a fool she was! How naive! Betrayed by her body and her inexperience as a woman.
After a long shower, she knew that she had to get back to the mainland, and back in her safe male body as soon as possible! She'd never be able to explain this.
