INSIDE..ME" she says calmlyThen it hits me, my dick is inside my sister! I'm not as shocked as I should be. I just look at her."oh my god" came the wh...sper out of my mouth, but my dick twitched and she gasped and in turn made me gasp AND in due course made my cock twitch again. This time she let out a little moan.I twitched and we gasped for about 5 minutes before she said,"You're in me"."Yes I am" I said.She looked away from me thinking, my cock twitched, she gasped.Trying to catch her breath. All the time she was doing this, she was sucking greedily on my nipples. she pulled her wet fingers out and forced them into my mouth. I sucked them almost ravenously.. savouring my pussy juice on her fingers, she then moved in to kiss me. Our lips met and her tongue probed my mouth as she enjoyed the taste of my pussy on my lips.Her hand then wrapped around her strap on, and with her hand wrapped around the base, she began to rub the large head at my pussy lips, slowly she begins to slide it. " I said "Well I certainly got quite an introduction didn't I." Lisa grinned and said "Tiny and I talked for hours last night and I told her about all the fun things you and I have done and she told me how much she would like to have some fun too. So I made up this plan letting her get in the shower first, knowing that you would likely come in thinking it was me." "Well your plan worked didn't it. What can I say but Thank You for the pleasant surprise." Lisa pulled the shower curtain closed. She did as I said, I could see the outline of her tits as they fell to the sides of her chest under that shirt. nipples low and hard. I still didn't make an attempt to touch them.As I crawled down between her legs she propped her head up with two pillows, clearly she wanted to watch this time. I did exactly as I had done the last time and she came just as hard and what seemed to be a half dozen more times and this time she grabbed her tits and nipples the whole time. We lay in the bed after.
