It all started when Janie came to visit us most evenings.
She was my wife's brother's girlfriend, Janie was 18 tall slim and beautiful with lovely tanned skin.
We all got on well and teased and joked around a lot and for a laugh I sent away for a catalogue of skimpy underwear for men which everyone had a look at.
It didn't take me long to order a couple of pairs of very brief, briefs and soon when I arrived home from work the package had arrived.
My wife her brother and Janie were sitting chatting as usual as I unwrapped the briefs.
I held up a pair, they had a full back and just a pouch at the front and of course everyone laughed and I was dared to model them.
I went upstairs stripped off and put them on, I started to tremble, they were very brief and I wasn't sure if I had the nerve to show everyone.
Excitedly though I pulled them up as far as I could, took my shirt and went down to the room where they were and stood holding the shirt in front of me to pleas of, come on let us see.
I closed my eyes and dropped the shirt to howls of laughter; I can still feel my face burn with embarrassment.
When I calmed down a bit and felt a bit braver, I told them defiantly that I would stay like this for the rest of the evening, which I did.
As the evening went on and I became more relaxed the briefs gradually worked their way down until they just covered my dick, leaving my pubes on show, I even got up and walked out of the room and back a few times just to show off.
From then on, it became a daily routine for me to have a bath and then sit around wearing only the briefs, then, as I became more and more at ease I took it a stage further by wearing only a small towel around my waist.
I really enjoyed the feeling of sitting usually beside Janie almost naked, but showing nothing.
Then I couldn't believe my luck, Janie asked us one evening if she could stay with us for three months while her parents were abroad, oh yes!
This gave me the opportunity for more adventures, Janie would get up early in the mornings to get ready for work, so of course I'd get up too and join her for a morning cuppa, wearing just my briefs.
I'd sit beside her on the sofa chatting, usually my wife would stay in bed, so it was just the two of us, then I discovered that if I crossed my legs and lay back a little the briefs would slide down giving her a view of the root of my dick although I had no intention of taking it right out in front of her.
Some mornings I would oversleep and didn't hear her get up and leave for work, so I developed a little fantasy routine to have my compensatory buzz, which would put on a full show of my whole body for her to view.
I'd get out of bed naked have my morning pee and come downstairs with just a semi hard, which I reckoned made me appear not so small.
I'd stop outside the living room door and gaze out of the small window at the side as I opened the door with my back to it.
