I lost track of time, as did Betty. In fact, we both passed out wrapped in each other’s arms.I woke up and it was dark outside. Betty was curled up ...ext to me, one leg d****d over mine, her head resting in the nape of my bare shoulder. I gently pulled her long hair back and kissed her forehead.Betty smiled.“I wonder,” she said softly, “How Bob and Danny are doing.”Betty’s question caught me off guard. Without even thinking, I replied.“They’re probably fucking each other’s brains out.”No sooner. I gave her a soft little shake to prove she was still very sound asleep which gave the guys confidence they could get away with it. Neither of them lasted long before popping off. She barely moved while they cautiously pumped. We whispered stories we remembered about girls getting fucked while passed out, cheerleaders at after game parties, aunts passing out at poker games. Girls waking up not knowing which guys or how many had cum in their pussy. The guys did feel guilty for fucking my wife. Females make the stuff that lubricates and lets your dick slide in and out freely. It's a sign of welcome from them, a sign they want it. They produce it very easily, so I like to use it.But I always let a girl do more with the vibrator than just get herself wet. I'd let her do herself with it until she got excited. I always remembered to stick a rag of some kind in her mouth first in case she was a screamer. Sometimes I'd just let her come. Then she'd be lying there relaxed and happy as I. “are you alright?” she asked giving me a smile. “irrr, errr yes sister.” She then sat down and i found myself looking at her nipples every so often. She again caught me out a few times and always just gave me a smile and each time i would blush even more. Why were her nipples still so hard? I had never noticed that on her before. Over the next week i didn’t get a chance to perve on her, but something i noticed, sis was dressing a lot more casual around the house. Hardly ever wore a bra anymore.
