I told her I would like her to watch or take part. Happily she’s not exactly averse to the idea. Not one bit. We’ve fantasised about this a lot to...gether and she has the most beautiful orgasms thinking about me with another guy. Nothing like this had ever actually happened until my wife and I took a vacation in Amsterdam. On the first day we did the usual tourist things: a trip along the canals, The Anne Frank museum, dinner in a wonderful Indonesian restaurant and back to the hotel to conk. Her whine told me I was succeeding in my aim to drive her slowly over the edge. And to pay her back for giving me a sleepless night after our phone call.After toying with her nipples until they stood out like two hard points, I slid my hands down and unbuckled her belt. My jeans were large enough I didn't even have to unsnap the button to slide them slowly over her hips and down to the floor where she stepped out of them, turned around, and almost ripped the buttons off my shirt. Her face was. Waves of desire surged through her as he fondled her quickly stiffening nipples."Oh, Bob," she sighed. "I just can't help myself." Me either, Sis."She giggled even while he frenched her. "What would Mom say?" She'd probably be jealous and want to get in on the action."She let her legs fall open as his hand explored her bush. He fondled her through her panties. Her wet panties."Mmmmmmm, that feels good," she said."Let me touch you here," he said and she opened her legs wider.He slipped a finger. A little after 6:30am I heard a soft tap at the door. I got up and made my way to the door and cracked open. Standing there in all of her barely 4'10" height was my airplane seatmate.I opened the door fully. "Do you need help with your luggage?" I teased in a whispered voice so as to not disturb other rooms in the hall."No, but I need to ask why you read my conversation." she said with slight annoyance."Well, I didn't mean to. But I read what you said about being seated 'next to a fine ass.
