The Irresistible Twins

Chris Evans woke up to the sun shining down on his bed, which was bouncing abnormally.  As he was clutching to the last remnants of his dream, he opened his eyes to see what was causing all the shaking. Upon seeing Josh, his best friend, he could help but smile. “Bro what the hell” he said, his voice still filled with sleep. “Happy Birthday! Now get up! Look how nice it is! And we have tones of things to prepare for tonight” Josh answered excitedly. “Happy birthday to you” he replied. Chris looked through the window, for a 1st April, it looked like it was going to be a beautiful day. It was a Saturday and his and Josh’s 18th birthday. His parents weren't so strict on alcohol consumption, so the party was gonna be a lot of fun. Chris got out of his bed, his usual morning wood flopping around for all to see. Josh looked away, making a scene, while this was not the first time he’d seen his friend stark naked. They had always known each other’s. Their mothers were high school friends and they were born on the same day. They had been play mates early on. When they were 5, however, Josh developed a bad leukemia requiring a bone marrow transplant. As they couldn’t find a donor, Chris’ parents had had him tested, and surprisingly, they were a match. They had every since been linked by a deep brotherly love that had got them to be nicknamed by all the Twins. They grew up at each other’s house, calling their parents Mom and Dad, for Chris biological parents, and Mam and Pop for Josh’s parents. Despite the nickname, they looked nothing alike. Chris was short, at 175cm tall and 70kg, with only a slight muscle definition although he tried countless work out routine and diets. He had brown hair which he kept short. Josh, on the other hand was taller at 187cm, and he was the football captain and had the muscles to match. He had dirty blond hair which he kept longer and pulled back.  Due to the countless hours playing sports and the afterward team shower, they knew what each other looked like naked. Chris wiggles his c**k for good measure to annoy Josh and said “that must be the only part true in the Twin” They both laughed as Chris made his way to the bathroom and closed the door. He looked at himself in the mirror and sighted. If only he could build some muscle like Josh. As he was picturing himself stronger, he felt a tingle in his arms and hands. Taken by surprise, he lost his train of thoughts. His eyes wonder to his still hard c**k. He was proud of it, but only when erected. His manhood was 17cm long and 14 around. But he was a grower, so soft, he didn't have any bulge. As he was jumping in the shower, starting to stoke himself, his mind went to Erika, as it often did.  Erica was a super hot girl from his class, a couple weeks older than him. She had the perfect cheerleader body. She also was Josh’s ex. Chris had met Erica when she started dating Josh, and they got along quiet well, although Chris hoped for more, even more so after Josh and her had broken up. As they shared everything, he had seen pictures of her naked, and he knew she was wild in bed. After finishing off and getting out of the shower, Chris went downstairs to have a quick breakfast and help his mother set up the party.  Chris's parents, Andrew and Anne, were waiting for him in the kitchen with Josh. They were both in their late 40's, super fit and looked nothing like him. His mother had a lean and toned figure, thanks to her many hours of yoga and tennis, long black hair, and dazzling blue eyes. His father was 190cm tall, 100kg of pure muscle, jet black hair and deep green eyes. Chris’ eyes were green but neither deep nor dazzling. "Happy birthday" they shouted as he walked in the kitchen.  He gave both his a hug and thanked them.  Turning around, he saw a bunch of pancakes waiting on the table, with freshly made orange juice. His mother really knew how to spoil them. While the men were slowly enjoying the food, Anne left to buy more stuff for the party. She quickly mentioned to check that the pool heater was on and was out the front door. As soon as the door was shut, his father took a much more serious look and announced: "Boys, now that you're 18, it's time I tell you our family secret."
