The next day we joined up with Tessa's mum, dad and grandmother for breakfast at a local cafe. Whether or not Tessa had told them to be friendlier to me, I don't know, but the atmosphere was definitely less hostile than it had been at the party. I still wasn't comfortable in their presence, and doubted I ever would be again, but at least everything was now a bit more civilised.

We went back to Tessa's parent's house after we'd finished eating breakfast, had a cup of tea, and then departed for home. I did ask Tessa if she wanted to stay longer, but she was fairly insistent on getting home. We got back home and spent the rest of that day plus the next largely lounging around the house doing nothing.

Then, on the Tuesday, it was Halloween. Being a big fan of horror movies, Halloween is a favourite time of year for me. In the morning, we went out to get in some candy to give out to any 'trick-or-treaters' we may get later in the day, then spent the rest of the day carving pumpkins and putting some spooky decorations up outside our front door.

It was 4pm when Tessa said we needed to get dressed for the evening's festivities.

"But we're not going out, are we?" I asked.

"No", she replied. "But we need to get into the right spirit for it. Plus, Halloween's one of the rare occasions we get to fancy dress. I don't want to miss out on that just because we're not going to a party."

With that said, she led me upstairs to our bedroom.

"I've got a few options for you, babe. You can choose which one you want to wear."

She walked over to her wardrobe and pulled three items out from it. She held each one up in turn for me to inspect, before laying them side-by-side on the bed.

Option 1 was a witch costume. I say 'witch costume', it was essentially just a black latex bodysuit with a mesh miniskirt. It was only obvious that it was meant to be a witch's costume because of the accompanying hat and broomstick.

Option 2 was a devil costume. Again, it was only discernible as a 'devil costume' because of the horned headband and three-pronged staff that came with it. Other than these items, it was just a red bodysuit with thigh-high red leather boots.

Finally, option 3 was a Wonder Woman costume. This consisted of the classic red corset with gold trim, an unbelievably short blue skirt with a starred pattern, and her iconic headband. There were also gold bangles to wear on the arms, a lasso rope, and red stockings.

Whilst I wanted to wear all of them, in truth, I knew that none were appropriate for answering the door on Halloween. If I was going to an adult's Halloween party or was wearing them whilst roleplaying with my wife, I probably wouldn't have hesitated. But to wear when answering the door on Halloween night...

"Babe, I can't wear any of these. They're all a bit...y'know?"

"All a bit...what?"

"Revealing...risqué...slutty, even."

"But you do like them all, don't ya?"

She had her hands on my ass and was grinning from ear to ear. I couldn't help but nod in answer to her question, even if it was rhetorical. Tessa looked into my eyes and said:

"Choose one of them now. Put it on, then wait for me downstairs."

She gave me a kiss before perching herself on the edge of our bed, awaiting my decision. I decided on the Wonder Woman outfit. Although it was hardly 'PG', it was easily the most acceptable: the other two were better suited for a porno!

I stripped to my white cotton bikini panties and pulled the corset around my abdomen. Tessa pulled the strings at the back; it was so tight, it wasn't particularly easy to breathe! And hardly ideal was that it barely contained my boobs, which were threatening to spill out over the top of it.

Corset in place (just!) I stepped into the skirt and pulled it up into place. There was no wig, so I was a blonde-haired Wonder Woman for the day. I completed the ensemble by donning the headband, stockings and bangles.

"Go over there, babe", Tessa directed, pointing to where she wanted me to stand. "Hands on hips, looking up to the ceiling. Bit heroic, like."

I adopted the proposed stance. She snapped a picture.

"Beautiful", Tessa said, clearly happy with the shot. "Right, while you wait for me to get ready, why don't you go downstairs? I'll not be long."

No protest from me. I went downstairs and chilled on the sofa. I was waiting for quite a while and there was no sign of Tessa. The doorbell went in this time, and I was forced to answer as Tessa clearly still wasn't ready. I was incredibly conscious of the outfit I was wearing as I made my way out to the hallway to answer the door. My tits were very much on display, accentuated as they were by the corset, and I wondered if my panties would be visible owing to the shortness of my skirt. But it was too late to change anything now, and I couldn't possibly let the poor 'trick-or-treaters' down by not answering the door. I took a deep breath and opened the door.

"Twick or tweat", said three adorable little children. One was a little boy wearing a pumpkin costume; one was a little girl dressed as Elsa from 'Frozen'; and the other was another little girl dressed as a Cruella De Vil. They were being chaperoned by a good-looking, grey-haired man, who I assumed must have been their father.

I commented on how amazing they each looked, then held out the bowl of treats for them to help themselves. As they took some sweets for their buckets, I looked up and noticed that the man was stood looking straight at me. He was slack-jawed and his eyes looked like they would pop out of their sockets if they were any wider. I felt simultaneously flattered, unnerved, conscientious, and a little turned on!

The man seemed reluctant to leave the doorway, but did so eventually (admittedly after a period of time that maximised the socially permissible length). They left and I shut the door, just as Tessa was making her way down the stairs.

She was wearing a witch costume, but it definitely wasn't the one she had left out on the bed as an option for me to wear. It consisted of a long black and purple dress, black tights underneath, long black gloves and a pointed witch's hat. Her make-up was incredible, with purple eyeshadow and purple lipstick, plus a pale complexion. She looked the part as the evil witch, but was undeniably sexy with it, even with the wart she had put on her cheek.

"Wow!" I exclaimed. "You look fabulous!"

"Thank you, dearie", she replied, putting on a stereotypical witch's accent as she said it. "Pop to the kitchen and get us some wine. I'm parched."

I scurried to the kitchen and returned with a bottle and two glasses, plus a large bowl of popcorn. We spent the evening sat in our fancy dress, drinking wine and watching horror films. Intermittently, the door would go for some 'trick-or-treaters', and we settled on a rotation where we'd alternate which of us answered the door.

What was quite funny was that Tessa looked so realistic as an evil witch that she definitely spooked out most of the children who knocked; one audibly started crying as she set eyes on Tessa, bless their heart! I didn't have that effect, luckily, but I was definitely attracting the gaze of the dads who were chaperoning their children. They mostly looked pleased (and aroused) at the sight of me. I didn't get the same reaction from most of the women who set eyes on me, tough, most of whom looked on with a trace of disgust (and perhaps a bit of jealousy!).

Admittedly, after overcoming my consciousness over the scarcity of my outfit, I began to enjoy answering the door. Perhaps a bit of me was enjoying attracting the male attention, if the truth be told. By 7.30pm, Tessa stopped answering the door and sent me to go each time. I didn't protest.

We were partway through our second film of the evening when the door was knocked. I went, and was shocked upon opening the door to be greeted by a group of the children from my year 7 class. I was deeply embarrassed, given how I was dressed, but they were perfectly polite, took the candy I offered them, then went on their way. Luckily, no reference was made to the way I was dressed.

I returned to the living room and Tessa asked why I was blushing so deeply. I explained who had just knocked; she just chuckled briefly, and remarked that at least I wasn't wearing just my bra and panties this time. I laughed and agreed, but a part of me felt that this costume was somehow worse.

We were not disturbed again for quite some time, so we assumed that our evening answering to 'trick-or-treaters' had concluded. But at 8.45pm, we had more visitors. I tried to argue with Tessa that we should stop answering the door now as it was getting late, but she insisted I continue answering. I made my way to the door while Tessa sat watching the film, eating popcorn and downing wine.

Our visitors on this occasion were none other than Billy and Benji from my year 10 class!

"Ayup Miss", Benji said, "trick or treat".

I was stunned. I wanted to say: "what the fuck are you two toerags doing here!?" but instead I stammered, "oh...hi boys...aren't you two a bit old to be trick-or-treating?"

"We could say the same thing about you dressing up like that!" Billy retorted, inspiring guffawing laughter from the pair of the bastards.

Benji cut across his pal. "Look, Mrs McGrath, we got a tip-off that Wonder Woman was serving up sweets people who knocked at her house. We couldn't believe what we were hearing, so we thought we better take a look for ourselves. I must admit, I'm surprised to find out my English teacher is a superhero, but the evidence is plain to see."

I couldn't believe what I was hearing. If my understanding was correct, word must have spread about how I was dressed on this evening of October 31st. And now, my pupils were coming round just to get a view of the rumours for themselves.

I was unable to conjure any retort or witty remark. I stood there motionless for quite some time. I was frozen.

Billy cleared his throat. "So, can we get some sweets or what?" Both boys were smirking, evidently revelling in my visible discomfort. I held out the bowl for them to take from, which they did, greedily, just as Tessa came to see what was taking so long.

"Um...", I stammered. "Tessa, this is Billy and Benji. They're in my year 10 class."

"Oh, right", Tessa said, her confused expression indicating that I hadn't sufficiently answered her initial query.

"And whom might you be, love?" Billy asked Tessa.

'Fuck me!', I thought. 'How has a teenage boy got the gall to be so blatantly cheeky.'

"I'm Tessa, Denise's wife", Tessa replied. Fortunately, she was retaining her composure much better than I was.

"Holy shit!", Benji exclaimed. "Never knew you were a lesbo, Mrs McGrath. Mad respect!"

The boys giggled. Tessa looked at me, baffled. I looked back at her, incredibly embarrassed.

Tessa cleared her throat and snatched the treats from my hand, preventing the boys taking any more. "Right, boys, you've had your sweets. Me and Denise are going to have some special time now." She flashed them a sultry wink. "So, do us a favour little boys, and fuck off." With that, she slammed the door in their face. She locked it up afterwards, indicating that the night's festivities were over (thank God!).

We returned to the sofa and digested what had happened. I chastised Tessa for swearing at the boys, as I'd no doubt get some flack for it when we returned from half-term. But, deep down, I was pleased, as she'd been brave enough to say what I wanted to but couldn't. Tessa said we shouldn't talk any further about it, which ended that particular conversation. I still replayed it over and over again in my mind, worried about how it would play out in the classroom the following week, but that had to stay inside my head, as I was unable to articulate further on the matter.

The door was knocked on a further 4 occasions after that, but we didn't answer it. The blinds were now drawn, the door was locked, and we sat in the dark (to make the film feel a bit spookier, is what we said, but really it was to make it clear to knockers that we were no longer open for business - not that it stopped them knocking!).

We finished our film, popcorn and wine, then headed upstairs for the night. What followed was another photo shoot, at Tessa's direction. She ordered me into a number of superhero-y poses and snapped some shots. I shed my skirt, and more photos were taken. Then, Tessa pulled out a dildo, handing it to me. We'd not taken photos with the toys before, but were clearly moving onto the next stage of her 'project' now.

Taking the dildo in my hand, I naively asked: "what do you want me to do with this?"

"Play baseball", Tessa sarcastically remarked. "Have a little suck on it first, then start to use it. I'll let you choose how you use it, and where."

It had a suction cup, so I suctioned it to the headboard of the bed. Down on all fours, I crawled towards it. Tessa had now taken up position to photograph me from the side of the bed. I looked towards the camera and saw Tessa nodding enthusiastically. I tucked my hair behind my ears (luckily my headband was still keeping most of it back) and began to work my mouth up and down along the shaft.

It was a plastic material, 7 inches, veiny, and black. I was only getting my mouth halfway down the shaft initially, but Tessa ordered "deeper!", so I worked my way further down. I was gagging as I got all 7 inches inside my mouth, but Tessa told me not to stop, so I didn't. I kept going, my saliva now coating the phallus, until I was eventually told to stop. I was surprised to find myself pretty tired as I removed my mouth from the cock.

"Start using it now, babe", Tessa instructed, and so I took it from the headboard and rubbed it gently against my vagina before slowly working it inside. My panties were removed by this point, but I was still encased in the corset. I worked the object back and forth, beginning slowly and quickening as I went. I was beginning to enjoy the experience of a penis being inside me more than when Tessa's fingers explored my orifices.

Tessa spurred me on, calling instructions from time to time as well as generally encouraging me to keep going. I started on my back, then moved to all fours, then moved back to lying on my back. I was getting better at controlling my pleasure during sex, and lasted a lot longer than I had in my initial lesbian experiences with Tessa. But soon the moment of climax came, and I squirted everywhere. I wouldn't let this on to Tessa, but this was the best orgasm I'd ever felt.

I momentarily wondered what sex with a real man would be like, but banished the thought no sooner than it had appeared - I couldn't be thinking like that! I was married to a beautiful woman, and must remain loyal. It was wrong of me to think about sex with anyone other than Tessa. It betrayed the sanctimony of marriage.

I was sprawled on the bed after finishing my session. Tessa took one final photo of me spread out on the bed, utterly exhausted. She put down her phone and knelt by the bed. She released me from the corset (which was a massive relief!), leaving me stark naked. She made her way round to face me at the other side of the bed.

Stroking my hair, Tessa said: "Good job, baby girl. Very sexy! Go to sleep, now. We'll talk more in the morning." She got up and left the room, turning the light off as she went. In the darkness, I quickly drifted off into a deep and dreamless slumber.
