I looked at my Mother in Law, embarrassed by her request. But also exhilarated. I knew this was all part of the game she played with me. She knew how to push the right buttons to make me humiliated but also sexually excited.

I clambered awkwardly over Ben, who was smiling knowingly at me. This was obviously pre-planned by my Parents in Law. In the toilet I did a nervous pee before removing my knickers. Once my jeans were back in place I stuffed my knickers in my pocket and made my way back to my seat.

Again I had to clamber awkwardly over Ben as he made little effort to make room for me to reach my seat. Once seated I reached into my pocket, extracted my knickers, and went to hand them to Jane

'Put them back in your pocket' Jane commanded quietly. I frowned at her confused, but obeyed.

'Now stand up, and hand me your knickers like a good young lady should.' I was so embarrassed, as I was sure neighbouring passengers could not have helped but overhear my Mother in Law's request.

Gingerly I stood up, extricated my knickers from my pocket once again, and holding them in a tight ball in my fist passed them to my Mother in Law's open hand. To my horror she let the ball unravel in her open palm, so that it was clearly evident to anybody watching that she was holding a pair of knickers.

'Good girl', she smiled, as she placed my knickers in the pouch of the seat in front of her.

Hastily I sat down, pulled the blanket over me, and settled back once again.

'Now remove your jeans to your knees'

I was mortified by this request. Although I had a blanket on my lap, it would make me very vulnerable to exposure. My heartbeat increased, but damn it all, so did my excitement.

Trying to look as inconspicuous as I could I reached under my blanket and unzipped my jeans, and very gradually edged them over my buttocks and down my thighs to my knees, being very careful to ensure my blanket stayed in position. Once the task was completed I breathed a sigh of relief and relaxed back into my seat, trying to act normally. However my Mother in Law was not finished with me yet. She wanted to take my humiliation a few steps further yet.

'Have you completed the task'?

'Yes ma'am'

'Show me.'

I looked around to ensure no one was obviously staring at me before carefully lifting up the side of the blanket so that Jane got a peek of my naked thighs.

'Good girl. Are you wet?'

I couldn't believe this woman. Would she never let up? And to make matters worse I knew I was sexually excited and my lips were swollen, which meant I was in distinct danger of leaving a wet spot on the seat.

'I am excited,' I confessed

'Which means you are probably wet' My Mother in Law pressed the issue, speaking too loudly for my liking.

'Yes Ma'am' I admitted in defeat.

She gave me the same sort of look a mother would give a naughty child who had just spilled her ice cream. Jane then reached into her handbag and conveniently produced some tissues.

'Am I going to have to do it for you?' Jane enquired, holding the tissues in front of me.

'No Ma'am. I will.' I virtually snatched the tissues from her, and again tried to look totally inconspicuous as I raised my butt slightly and placed the tissues under me.

I again relaxed back into my seat, half expecting my Mother in Law to make further demands, but fortunately she did not. Half way through the flight I needed to pee again but decided it would be in my best interests to hold it in until we had landed. Jane made me wait until the flight had hit the runway before allowing me to pull my jeans back up again. As we departed our seats my Mother in Law took out my knickers and dropped them on my seat, on top of the pile of slightly soiled tissues. Very embarrassing!

At the airport we picked up a rental vehicle, and as we drove from the airport Jane looked back at me. She did not need to say a word. I lowered my jeans, and at least did not have to worry about my knickers. I even reached over so that she could hand me some fresh tissues. I actually fell asleep with my trousers at my knees, exposed to passer-by's.

When I awoke we were driving along a bumpy roadway, and looked around to see that we were on a small ranch, and were heading up to the homestead.

Jane looked over and noticed I was awake. 'You had better pull your jeans up little lady.'

I was so groggy from my sleep that I had forgotten about my nakedness. Hastily I made myself presentable.

As we drove up to the house I noticed Ben's business partner, John, and his young wife Debbie, standing on the porch waving at us. I groaned inwardly with trepidation. I could well remember the mixture of disgust and unbelieving fascination that Betty had displayed when she and John witnessed my discipline at the home of my Parents in Law. To make matters worse there was also another young couple standing on the porch beside Betty.

I was plainly very uncomfortably, not to mention embarrassed, as everyone greeted each other with great warmth. I was introduced to the young couple, who turned out to be Rachael, Debbie's eighteen year old youngest sister who was on vacation for a few days, and her boyfriend Troy who looked to be a similar age.

It was very late at night so we all retired very soon after our arrival, and I was relieved my Parents in Law made no further demands of me. I was a little dismayed to find I was sharing a room with Rachael and Troy, however everyone was so weary that sleep came easily.

The next day we awoke to glorious sunshine and sat outside having a leisurely cooked breakfast. Rachael and Troy turned out to be a very friendly, outgoing couple and we quickly bonded. Late-morning we decided we would all go horse riding, which was great for me as I had never ridden a horse before. We had a lot of laughs as I helped Rachael and Troy round up the horses and they showed me how to put the saddles on. They had plenty of horses, enough for all seven of us to go riding.

To be honest, I would have preferred to just go off riding with Rachael and Troy. I was constantly weary when I was in the company of my Parents in Law. I never knew what embarrassing big surprise they would hatch up for me. However I hoped that there would be safety for me in numbers. I should have known better!

Riding a horse turned out to be a lot of fun, although a little tough on the backside. We rode into the hills for a couple of hours before stopping beside a picturesque little lake for a picnic lunch we had bought along with us. The isolation and peacefulness was such a wonderful contrast to the city life I was use to.

After lunch Rachael, Troy and I played in the huge rock formations beside the lake. I really did feel like a young teenager again. It was great to let go the burden of adulthood and feel like a free spirit.

By the time the 3 of us rejoined my Parents in Law and John and Debbie we were all hot and sweaty.

'Why don't you 3 young ones have a swim in the lake before we head off.' Debbie suggested.

I was not sure if Debbie was trying to be sarcastic by grouping me in with the 'young ones', considering her and I were about the same age, however I knew better than to react.

Rachael and Troy jumped at the idea and were soon stripping off their outer clothing. Both were wearing boxer shorts, and Rachael had a full sports bra supporting her surprisingly full breasts. Being a typical woman I felt a small snippet of envy that she was almost two bra cup sizes bigger than me. Importantly their undergarments were not revealing so they were happy to strip off in front of strangers and dive into the lake.

I, unfortunately, was not in such a happy position. For one thing, I was not even wearing a bra. Since I have small perky breasts I often go braless under my tee shirt.

Plus my knickers were a very small pink lacy thong that left very little to the imagination, if you know what I mean. When we dressed this morning I had no idea we were even going to be riding horses, let alone swimming in a lake. I felt a bit annoyed that Rachael or Troy hadn't given some sort of warning as to what we might be doing for the day. I could have at least had the opportunity to dress more appropriately. As it was I felt more than a little foolish as Rachael and Troy waved at me to join them in the lake.
