Im a crossdresser, have been since my teens. Im married so everything has to be secret . I get my undies and clothes at charirty shops, a few miles away. This particular day I was in a shop and I saw this lovely green satin slip. I touched it and knew I had to have it. The shop was busy, so I mouched around, waiting for it to clear. The male assistant kept looking at me, I felt nervous. Finally 2 customers and me were left. One left, then the assistant said excuse me a moment madam, I have to lock up its my dinner break. He put the closed sign up and served her. He let her out the closed the door. Right sir, what are you buying? I put the slip onto the counter. He smiled, is it the correct size sir. I said it will do. He said no sir, we don’t do refunds, I suggest you try the garment on, it is for you? The shop is shut and we have changing rooms, and with that I felt myself being led to the changing room. I stripped off and put on the slip, it felt cool and clung to me just how I like it. A voice said is sir ready, and the curtain was pulled back. I just stood there. Very nice sir, fits u perfectly. And then he stroked down my body, cupping my little tits, first, then down my waist, then squeezing my ass. Has I didn’t resist, he moved closer and his hand rubbed over the front of the slip, near my bulge. He said,sir does like this slip doesn’t he? You getting hard aren’t you? I could barely croak, yes. He kissed my neck and grabbed my cock through the silky slip. You like he said? Yes I said. He continued to wank me, smiling as he did so. Are you married he asked? Yes I said. So you wont want a love bite on your neck then? I said god no. he said somewhere else then. He knelt down and his head disappeared up the slip. He was sucking me, god it felt goooooood. He kept sucking and I knew I was gonna cum. I told him but he kept sucking. I came off, I cudnt help it. He sucked me dry. I felt drained. He said shall I wrap the slip for you? I said yes please and took it off. He said oh dear, I cant sell u this, I said why not? He said its soiled look at the front. Let me find u something else. He rummaged around and came back with a black shortie nightie. Try this on he said. I put it on and it felt gorgeous. His hands were all over me and I didn’t care. He turned me round and felt me all over. Then his hand was feeling my ass. His fingers was feeling up my ass. Cos I didn’t object he went further. Fingers up me, twisting, me moaning. I thort I heard a zipper being pulled down. It was. I felt his knob, caressing my hole. You want it don’t you babe he said? I cudnt speak, I nodded my head. He pushed hard into me. Oooooooooohhhh I yelped. He slid out then in again. I yelled out. I cudnt yell enuff, he was ramming in and out. Moaning, saying dirty things,.he pounded away at me and my ass was clenching on his cock like it had a mind of its own. He shuddered a few times and I knew hed cum He slid out of me and I turned round. He wiped his cock on the nightie. Sorry sir, I cant sell this to you either. You will have to just take them. I began dressing. He said, I will be here in 4 weeks time if sir wud like to call back? I will look out for something nice for sir. I said yes that wud be fine. He said before you go, I didn’t give you a love bite. I said where. I don’t want it to show. He smiled, it wont, but you have to drop your jeans and pants. I did so, he began to bite and suck my left ass cheek. It was quite sore. I pulled up my pants and jeans, picked up my soiled slip and nightie and he let me out the shop. Remember 4 weeks time he said. I said ok. We exchanged bodily fluids, but not names.
