Normally I would never enter my daughter's room without knocking; at twenty years old she's a grown woman and entitled to her privacy; but the door was slightly ajar, and some instinct made me just push it open and walk right in. So I suppose I got the surprise I deserved.
Zoë was sitting on the bed with a complete stranger, both were sideways on to me and didn't notice me enter the room at first. Zoë had a lipstick in one hand, and was applying it to the other girl's mouth.
Suddenly Zoë noticed me, and stood up, scattering make-up on the floor. She looked terrified to see me. The stranger also turned towards me, and I realised this was not one of Zoë's friends, but my own son, Scott! I stood there, stunned into silence, as I took in his appearance. He was wearing a shoulder length blonde wig; Zoë had made him up, and I have to say he looked stunning. But what shocked me most was the fact that he was wearing only a pair of Zoë's pale-blue silky panties, which were being strained to the limit by a huge erection!
At first I couldn't speak, I was so shocked by what I was seeing. Shocked, and I have to admit, aroused. Eventually I found my voice.
"You've made him up beautifully," I said to my daughter. "You look... lovely, Scott." I added, in a hoarse whisper.
"You're not going to kill us, then?" Zoë asked, her voice trembling.
"No," I replied, still shaken. "But I think we'd better finish the job off, don't you?" They both looked at me, uncertainly.
"Let's go to my room. My stuff might fit him better."
Once we were in my bedroom, Zoë and Scott started to relax. They realised I wasn't angry with them, but they were still unsure about what was going to happen.
"Come and help me find something," I said to Zoë. She started rummaging through the wardrobe, while I searched my drawers for a pair of stockings.
"How about these?" I said, holding up a pair of very sheer black hold-up stockings. Scott nodded, eagerly. His panties were bulging nicely again.
"Mum, I don't think those knickers really suit him, " said Zoë. "Have you got something a bit... sexier?"
I rifled my underwear drawer again and came up with a pair of lacy white panties and a matching bra. Meanwhile Zoë had picked out a white silky blouse, matching it with a short blue pleated skirt.
Now for the awkward bit. I knelt in front of Scott and pulled his panties down. His cock sprang free, and I felt tiny drops of precum splash my face. Scott stepped out of Zoë's pants and allowed me to put the white pair on him. All the time, my son's erect manhood was bobbing about only inches from my face. What the hell. I gave it a quick kiss and grinned up at him. The look on his face was indescribable. I pulled the panties up tightly around his crotch, his precum immediately soaking through the flimsy material. Zoë hadn't seen me kiss Scott's cock, and I wondered what her reaction would have been. Maybe the two of them had been a lot further; I really had no idea what they might have been up to together, but thinking about it gave me a warm tingle between my thighs.
Zoë and I finished dressing Scott. When we were done, he looked really gorgeous. With the bra stuffed full of tissues, he looked very convincing. You wouldn't have known from a first glance that he wasn't what he appeared to be. I wouldn't even have recognised him as my son!
"You've got some great stuff here, mum," said Zoë. "Can I try some of it on?"
"Why not?" I said. "We might as well all get dressed up!"
