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.
