Zoe

It was his younger sister Zoe, who slowly opened her eyes and smiled.
"Morning sweetie" she said softly as she reached behind her and silenced the clock, "sleep well"
"Umm, I guess" Jon replied, unsure of what to think, however he had a certain feeling that this was right.
"good, just wait there, I have a surprise for you." Zoe replied. She sat up and the bed covers fell away, revealing she was topless, and was wearing a pair of baggy grey boxers. She walked over to chest of drawers and took something out from the topmost one. Jon quickly surveyed his surroundings, and realised they were in his parents room, and in their bed. There was still a nagging feeling that something else was wrong. He looked down and noticed he was wearing a silky black negligee and a black thong that seemed to fit rather snugly on his lower half. He quickly patted his groin and to his surprise found his penis was gone.
"Don't start without me" Zoe replied as she returned, Jon looked up and saw her stood next to where he was layng, her groin was just above his eye line and he could see a prominent buldge. She handed him a small box.
"Happy anniversary" She grinned. Jon opened it, and saw a silver necklace inside. Suddenly he felt his heart flutter.
"OH Zoe, it's beautiful" He sighed, "How can I make it up to you?" he found himself asking. A wide grin broke over his sisters face.
"Oh I think you know" she said.
