In just a few more minutes she came walking out in one of my wife's sexy nighty and she looked very hot in it. She had a little robe that went with th... nighty wrapped around her. I am sure I had a look of shock on my face but with a smile as well. She spoke "I am sorry but looking around in her closet I found this and I never get to wear anything like this I hope it is not inappropriate or out of line" I just smiled and said "Nope you look very nice in it and I am sure Tina will not mind such a. To late Shelly and I eased the tip of my cock into her virgin arse, as my sister in laws arse ease tightly around my cock, I pulled back on her hair, pulling her hair tight she arched her back as I fucked her arse.Slowly she got used to the invasion in her once virgin arse, ever so slowly she started fucking me back, my god she breathed I never thought it would be this nice, obviously her slight pain was now overwhelming pleasure, Shelly moan and moved her arse to quicken up the fucking taking. ” I looked over at her. “So are you going to do something about it?” More quiet. More thinking.“I wouldn't know what to do,” she said finally, immediately realizing how stupid that sounded. She needed a little nudge.“Well I'm inviting him over to our place Friday night. We can grill some hotdogs, watch a movie or something. Then you two can talk without the whole world watching.” She just looked at me with an expression of amazement.****The next afternoon, Ainsely was nervous about coming to. "Why can't I move just a little?"SMACK!"Are you complaining, missy?" He hit me on my inner thigh, right above my butt."No master, I'm sorry." "Good. Now, the reason for this is, i'm working with electricity. If you were to suddenly move and the baton hit your cervix... let's just say you really don't want that to happen." For a while, Mike just stood at the end of the table, inspecting me. He opened the suitcase and put the isolated baton on the table. Then the cable snapped onto the plug.
