Summer had come and gone, and Diane and I had really settled into a rhythm. We had not discussed anything with our relationship yet. We remained lovers, but I felt as though she was feeling more. I hoped it was not just my desires affecting my perception. Neither one of us had taken anyone else into our beds all this time. Even though it had nearly been a year since we began, I was not nervous of where I stood with her. I honestly felt that if she came to me tomorrow and told me it had to end, I would walk away. I would be upset over it, as I really did feel something strong for her, but that was still our arrangement. I did not dwell on this, because everything seemed to be going wonderfully.
One thing that did change was that I was spending more time with her and Sean now. While I would come over for dinner, or visit on the weekends, we would get along famously, but I never slept over while he was there. Our adult encounters were only when it was just us. We still relished our lunch time quickies, and there were times that she would follow me home after work, and fuck me silly before picking up her son. There was also the one weekend each month that Sean was away with his father.
It was late October now, and being a big kid, I was looking forward to Halloween. Diane had made some plans for Sean, to take him Trick or Treating, and to a party, during the week, then to his father's for the weekend for more trick or treating. It was working out well for him as our area was having it early, and his father's area was having it on the 31st. He was very excited, and to Diane's surprise, he wanted me to help them with a costume. Like I said, I was still a big kid. He decided to be the wolfman, and I worked with Diane to get a good mask for him, and some clothes to fit the look.
Diane and I also planned on going to a costume party the weekend of Halloween. It was hosted by a coworker of ours. She was new to the company, and said she did this each year. She claimed she threw an awesome party, and there were always a lot of people. We were skeptical, but being nice, decided to go. Talk to others at work, no one else had planned to make an appearance. It looked like we would be the strangers at the party. Trying to play that to my advantage, I told Diane that we could get away with more since we would not know anyone. I tried talking her into something really sexy. Since I love this holiday, I am good at using prosthetics and such, so I explained I could make her look like anyone/anything but her. She reminded me of a couple of things. First of all, we would know the hostess of the party, and she would be seeing people from work that following Monday. Also, that we had not made it all public that we were 'seeing each other'.
Well, that was a dilemma. We talked it over, and decided to just show up together as if being a couple was not a big deal. If she told anyone from work, or if others showed up, so what? We still had to decide what we were going to go as, and she made it clear that she would not be showing off any of her 'fun bits' to people at the party. Yes, that is what she had taken to calling them. After looking online, I think she had maybe decided on a witches outfit that actually covered about everything, but the dress was form fitting, and clingy. So, it would show off her figure, but no more than a cocktail dress would. She agreed to let me put on a fake chin and nose, and a few other things. She would turn out to be sexy from the neck down, and hideous from the neck up. I had not decided yet, and could not make up my mind.
We went about the week, and I just could not commit to a costume. Before Diane ordered hers, she came to me with an idea for the both of us. "We could both go as one costume, like a horse or something."
A horse? Really? The kid in me felt that a horse was a rather lame idea, but at the same time, it could be goofy. Walking around in a two person costume, we could just be silly, and a few drinks might add to that. It could guarantee some fun. I relented, and she and I went to a shop to rent one. We tried it on, and had a ton of trouble. She was the front, and I was the horse's ass as it were, and we could not get in step, and Diane kept having problems seeing. The shop owner said that it would be best if I was up front as I could deal with the head better. We switched around, and found out she was right. Not having to deal with the head, we were able to get into step better.
It was not long before Diane started complaining that her back was starting to ache being bent over. The shop owner offered to help us adjust it so that I was bent over slightly, and she was closer to me, up against my back to support her. We found that this worked out well enough. When I got tired, I could stand upright, and she could stretch for a little bit, and when she got tired, I could lean over for her to rest. Looking in the mirror we were a rather squat horse. Oh well, this is for fun.
We rented the costume on Thursday, and went to her place to show her son. We put it on, and he cackled like crazy watching us walk around. We even did an impromptu dance in the costume. On Friday, after Sean left with his father, we tried it on again to get more practice. We had noticed that it would get rather warm in the costume, so we decided to wear shorts. Looking the costume over, I found that if we rolled up some clothes, I could attach them to the inside of the costume at the butt. It would sag normally, and with the clothes, it propped it up nicely. So, we would have jeans and some other shirts to wear if we decided to take off the costume.
Now, normally I would be staying the night, and we would be doing our best bunny impersonations, but I had some things I had to attend to first thing in the morning, so I would not be sleeping over. As I was preparing to leave, she pushed the front door shut on me, and backed me against the door. She slid to her knees, and undid my pants, and took me into her mouth. I was not even semi erect when she started, and she got to feel me become fully aroused in her mouth. She took her time, making sure to prolong this. She managed to work my pants to the floor, and helped me step out of them. She stepped up her efforts, and I worked my fingers into her hair. She had really come to know what made my legs quiver. I was never one for a slow blow job, but she learned how to make me like them.
After a time, she pulled my cock from her mouth, and just looked up at me while stroking it. With a grin, she quickly worked a finger in my ass. She had only done this one other time since the amusement park. She said it was something special for me, so she used it sparingly. She pulled it out until it was just the tip, and barely moved it, and continued to stroke me. I was dying; I needed her to quit teasing me. After a moment more, she slowly slid the finger back in my ass, and pressed against my prostate. She kept the finger moving slightly to really intensify the feeling. And then, all while looking right at me, she pursed her lips, and very slowly, very wetly slid her mouth over the head of my dick, and applied a light suction. I was nearly there when she stood up, and gave me a kiss, and with her mischievous smile told me that if I could not stay, I could not cum. She also told me to save it for after the party, and she would make up for it. With that, she gave me another kiss that knocked my socks off. It was a kiss full of promise of the weekend to come.
I pulled my pants back on, managed to tuck my erect penis away, and headed home. I did not manage to sleep much that night, and when 4 A.M. came, decided I might as well get started. I took care of everything I needed to, met with the people I needed to meet with, and was at Diane's house by 2:30. Since the party was at 7:30, and we planned to arrive at 8, we had time to get something to eat, and get a little more practice in the costume. She made us a nice early dinner, and made it clear that I was to behave. Knowing her as I now did, I know it was on purpose that she was an old, threadbare T-shirt with no bra, and my favorite jeans that showed off her magnificent ass. From the time I left the night before, I was perpetually aroused, and seeing her now, it was all I could do to keep from pushing her over the table, and fucking her for about 3 strokes, and shooting my load inside of her.
I managed to restrain myself, but it was agony. Any time she moved, her breasts wobbled enticingly. Her nipples remained constantly erect, never letting up. She made a point of reaching past me to get my plate, so that I got a close up view of them, even seeing down the front. She had become the devil. We ended up watching a movie instead of practicing. I am not entirely sure why. She insisted on watching Stephen King's It. Once it was done, we started to get ready for the party. She went to my bag, and pulled out my clothes to wear in the costume, and added hers, and we attached them to the rear end. She then told me that I had to change in here, while she got ready in the other room. "I would not want to temp you while I am naked. You have to remain pure until later."
"For crying out loud." I thought to myself. "You are going to be the death of me before the night is over." I told her.
"Trust me, you will be just fine, well at least until I get a hold of you later."
With a smile, she grabbed the back of the costume, and headed for her room, and shut the door. I grabbed my bag, and pulled out the remaining clothes. All that was left was a pair of gym shorts, and a T- shirt. I knocked on her bedroom door. "I need to come in for a second. You put my underwear in with the other clothes."
"Hold on. There are no underwear here. You must have forgotten them. Want to wear a pair of my panties?" She giggled at her wit. "Just use the pair you have on."
"You know I do not wear any with jeans."
"Oh yeah. Well, you are only wearing the shorts in the costume, so don't worry about it."
She had a point. Hell, I normally wore the shorts without underwear when in the house. Only if I went running or to workout that I put on underwear. Since I would be in the costume, I would not sweat it. Plus, maybe this would encourage Diane to play a bit inside the costume. It would be very easy access for her.
We could manage the drive wearing the legs, so we decided to do just that. It was chilly out, so being in shorts would not be very much fun. Diane would have the worst of it sitting on the clothes, but said she would be fine. I stepped into my legs, and pulled up the suspenders. "That was easy. I am ready to go." I called out. Diane came out wearing the same T-shirt she had been, and still no bra. She kept reaching in to mess with something. I started over to her, but before I got my second step she said "There, how do I look?", and she spun around.
