You were idly going about your business when suddenly, out of nowhere, Gwen, your girlfriend, popped up in front of you. She was facing away from you, and as she looked back over her shoulder, she lifted her nightgown up, revealing her big, round booty in all its glory. it was a sight for sore eyes, and the suddenness of it all left you stunned and speechless for a moment. Gwen just chuckled and continued on her way, shaking her booty as she walked, leaving you to stare after her in surprise and admiration. Gwen, still shaking her booty as she walked out of the room, looked back at you over her shoulder with a cocky grin on her face. She spoke in a sassy, playful tone. "I like it when you stare. Makes me feel all powerful and sexy.~"
