She tied my hands above my head to steel post so I was stretched. Then pull my legs wide with a spreader bar so open. She then put on her silk robe wi...hout a bra. My cock was rock hard feeling total open and not able to move. She took her time feeling my body never touching my cock until she shove an electric probe between my ass cheeks. Right into my anus and hit the button sending a shock right to my cock. I screamed AGGGGGGGGGGG as my ass clamped on the probe. NO please no more I beg never. I doubted my decision making, I kept asking myself, what the hell am I doing? She's half my age ... and a student. I felt guilty, this is the first time I've been with another woman besides my wife in over twelve years. I was nervous, I hadn't made love to any woman in a long time, does a guy get rusty? I was worried, what if I disappoint her, I'm sure she's used to younger men. But most of all, I was excited, damn I'm going to get laid!I asked her if I could get her something as we walked into. As she continued to push down on the top of her shaft, I licked all around the head and rubbed my lips against it before taking it in my mouth. My own cock pulsed and throbbed, I was shocked at how turned on this gurl could make me! I sucked her cock and felt it touch the back of my throat before I pulled off of her. I had to have her!I grabbed her slim waist and flipped her onto her stomach. She let out a very girly, high pitched “Awwhhh!” sound, surprised but happy to be man handled, I think.. .. Mary asked her, "how do you feel right now... ?" Laura gave a happy response of "great..." ... after Mary confirmed their shopping session for Thursday, she covered Laura's face with nice soft kisses. Then she asked Laura, as I was stroking her legs, "but how do you feel about all this ... do you think you'd want us to be together, as three friends and lovers?" I have to say, to this point, I wasn't sure if Mary truly had meant all she'd said previously to Laura, but now I was getting more.
