While Amy was out for the day, I did some chores around the house. I cleaned up and did the dishes. I later did some laundry, and then the thong I'd stolen from Amy came out of the drier I hid it under my boxers in my dresser drawer for later use.
I spent the afternoon doing some reading for classes and watched a movie from my own library. I couldn't quite get Amy off my mind though. I was delighted she was starting to show me more of her sexual side. What's more, I couldn't get it out of my head that she'd dreamed about fucking me. My mind got away from me and I started to wonder if maybe she'd want to act out the dream with me. But after a while I dismissed it as wishful thinking. She probably knew I wanted her, but was content with teasing me and letting me see her naked. She wouldn't probably get freaked out going any further than that.
These thoughts of Amy naked and fantasizing about fucking her gave me something of a massive erection. I decided to go take care of it. I went into my room, shut the door in case she came back and took out the red thong I'd stolen. I lay down on my bed and started jerking off while I thought about fucking her mouth while she caressed my balls till I shot a load deep in her throat. When I came, I came into her thong. I dropped it into my hamper and tossed a shirt on top of it to hide the panties.
I had good timing; as soon as I hid the evidence, I heard the front door opening, and the light footsteps I recognized as Amy's. The door closed. She was alone.
I went outside to greet her wearing black sweats and a tight white muscle shirt. I had shaved and done my hair, so I looked and smelled good, but I was bumming as far as clothes went.
Amy was still wearing the same tight black baby t-shirt and white kakis with no back pockets that fit like a second skin. "Hey, sweetie!" she said and gave me a hug. "How was your day?"
"Fine. Missed you, hon. How were the 'rents?"
"Oh, boring as usual. But they gave me money. I went shopping alone before I came back." She smiled broadly β she loves shopping.
"Get anything nice?"
"Oh, just this one thing." She reached into a shopping bag and pulled out a dark velvet nighty with lace at the top. The material became transparent below the chest, exposing the midriff, then solid purple again at the bottom. "It looks really hot on me," Amy said. "It's so short that you can see the bottom half of my ass and my pussy. You mind if I start wearing it around sometimes?"
I stammered, "No, not at all," trying to hide my secret excitement at the idea.
She smiled innocently, "Okay, great. I don't think I will right now though. Mind if I just lounge around in a pair of panties and this little tee tonight?"
"No, that's fine," I sort of grinned.
"Okay, great. You done with that red thong you borrowed?" she grinned wickedly as she asked.
I was caught. My face went totally red. "I β I'm sorry. I just β I couldn't β"
"It's okay, sweetie," Amy reassured me. "I'm just giving you a hard time. I don't mind. If you want to go through my lacey under things, it's alright," she giggled so adorably that it just made me want to fuck her and cover her in cum right then and there. But I restrained myself.
"Yeah⦠well⦠yeah, I'm done with it. It's in my hamper, I'll go get it."
Before I could, she ran off ahead of me.
"No! Wait!" I said, remembering that it was covered in wads of my cum.
Ahead of me, in my room, I heard an, "Ooooooooh!" of awe. "Damn, boy!" I heard Amy say as I came through the doorway. I saw her standing there with one finger hooked under the strap of the thong, the panties dangling there, soaked in still-wet semen. She laughed and smiled at me, "You cum like a horse, sweetie!"
I was completely embarrassed β my face totally red β and speechless.
