Darren and I were 18 years old when our eyes were opened sex-wise. Let me tell you a little about my family. Mum and Dad didn't get married until they were in their early thirties - Darren and I being twins arrived a couple of years later. We appeared to have a normal family upbringing. Dad was an engineer who kept himself fit by playing a lot of squash. He was a tall man around 6'3'' and weighing in at nearly 200lbs without too much fat on him. Mum was a housewife with a part time job. Being nearly 50 she wasn't as trim as in her younger days but she still had a reasonable figure. She was around 5'6'' tall with short, dark hair and laughing green eyes that still had a twinkle in them. Neither Mum nor Dad had any hang-ups over their bodies. On the odd occasions that Darren or I caught them in a state of undress they made no big deal about it. They never flaunted their bodies at us - until our 18th birthday that is!
Before that we had both been introduced to the charms of the female flesh through illicit school liaisons. As far as that was concerned we were no different from any other teenage boys.
It started out like any other birthday. At breakfast Mum and Dad gave us each a present. It was a small box and we were told not to open it until we had eaten our evening meal. We both naturally sneaked a look inside and found that we each had been given a black leather posing pouch! I spent all day at college wondering if that was all we were going to get.
In the evening we all sat down to one of Mum's special meals. We were allowed some wine with the meal and, coupled, with the beer beforehand, made me feel a little lightheaded. Mum was wearing a new dress that did nothing to hide her figure. Dad made no attempt to hide the fact that he still fancied her by taking every opportunity to touch her breasts or pat her bum.
After dinner we all settled in the lounge - Mum and Dad on the sofa - Darren and me in the easy chairs. Dad poured us a glass of brandy each that made me feel even warmer than I already was.
Suddenly Mum said. "It's time for you to open your presents. Go and have a look at what I bought you and then come down and show us what you look like in them". Darren and I went off upstairs to our rooms. I felt a bit self-conscious knowing that I would be parading in front of my parents with just a posing pouch on. However the feel of the soft leather embracing my cock and balls felt good and the feel of the elastic rubbing against my anus was peculiarly exciting! My cock started to get hard at the thought of showing myself to my Mum and Dad.
Darren came into my room and I quickly realised that he felt exactly the same as me. His cock, although not hard, was poking out of the top of his pouch. He somehow managed to stuff it all back inside the leather and we went downstairs to model our presents.
