Walking down the hallway thinking of going to the kitchen she heard Shaunas voice and decided to eavesdrop a little. You want to know what? she heard...Shauna giggle, A t-shirt and a pair of panties what about you? Oh I wish you were here wed have so much fun. You get me so wet sometimes, said Shauna excitedly. Lisas eyes went wide as she realized her fifteen year old sister was having phone sex. Stepping a little closer to the door she leaned in hoping to hear a little more. Oh I am my clit. Put on the red ones, a black suspender belt and stockings and come back down Fast!"She shot up the stairs, glad to be away from me, and I went into the living room to wait.I didn't have long to wait; mother came slowly into the room, and I nearly came there and then. By getting a too small a size her tits now bulged nicely over the top of the bright red bra, and through the thin material I could see her nipples, both erect. She was showing her true colours!!The panties were exquisite - her. At least now Ididn't need to stress about what to do with Rob that evening, and beingaround all those other people would certainly keep me out of trouble.But then I thought of something else - Erica was the same kind of'girl' I was! What if Rob clued in to her true sex? Would that give hima clue about me? 'Oh shit,' I thought, feeling panicked again - 'whathave I gotten myself into this time?'*****My 'beau" called the house while I was at Milestones on the Thursdayevening, to say he'd be. I replied, “No complaints from me, either.”I watched on in focused silence as Megan wound and pulled and tied the ropes around Chiara. She was methodical; her movements were crisp, clean and calculated. She exerted the minimum amount of energy possible. The precision of her movements and her rope handling skill was masterful. None of her movements were wasted. It was as if she tied to the beat of a metronome that only she could hear. When she had to move to position herself around Chiara's.
