It wasMaybe half an hour later, my mother then entered the room, which took me by surprise, as I was sure she knew everything that went on around the ...ouse."Gilbert I am off to work and I will be home late, be good" She said in the motherly way that all mothers have, she gave me a kiss on the forehead then went off to inform my sister.It suddenly came to my attention that I would be alone all day with Carla and Phoebe. Some minutes later Carla was back in my bedroom without Phoebe this time. Finally, Erica returned to the garage and opened the tailgate. I noticed, as Erica climbed in the SUV to unlock the cuffs around my wrists and ankles that she had changed her clothes and was now wearing a black silk robe with a pair of heeled slippers. As she moved around to free me, I noticed that she was not wearing a bra or panties under the robe. Once I was free of the cuffs, Erica slid out, tugging the leash to have me follow her. My legs were numb and it took me a while to climb out of. Her eyes flashed, and before I knew it, I was flat on my back. She had tripped me in a controlled takedown, and ended up straddling me, her body pinning me to the floor. My arms were held in a death grip above my head by her hands. "Now, will you play nice?" she mock-growled.I struggled to free myself, with limited success. "Now that you've demonstrated your ability to knock down an unsuspecting male your size, can you please let me up?" I said irritably.A polite cough came from the hallway.. "Oh, God, I gotta cum."Forgetting about everything but her own raging lust, the blonde teenager raced upstairs to her room. She closed the door, locked it and heaved a sigh.Nervously, she stripped off her top and looked at her budding tits in the mirror. "God, I wish they were big like Mommy's," she moaned. She caressed her sizzling flesh. Tiny goose bumps dotted her smooth silky skin.Her fingers trembled. She tore at her shorts, shoving them down over her slim girlish hips. With her heart.
