My Mom and Dad split up when I was a freshman in high school. She remarried when I was entering my senior year. To say I was pissed was an understatement, because not only did I have to live in a house with her new husband, I also had to put up with his squirrelly son, who was just a scrawny pimple-faced freshman.
I was the captain of the cheerleader squad and wanted nothing to do with a step-brother. I couldn't wait to graduate and move on to college. That day finally came, and I happily said 'adios!' and moved away. Although I had to come back on the occasional holiday, for the most part I was able to avoid the step-family as I continued my studies by taking summer school classes after my freshman year at university.
Unfortunately, my luck ran out after my Sophomore year. The classes I needed for my major were not offered that summer, so I reluctantly moved back to my home town, dreading the next three months of living with the "steps". As I begrudgingly drove to the house and started to unload my car, I was greeted in the driveway by a stunningly fit guy who had me doing a double take of his body. "Hi Tori!" he said as if he knew me. It took me several seconds before I realized that it was my step-brother Kent. 'Holy shit!' I thought to myself. This kid sure has grown up!
"Kent, you look amazing! When did you grow up?" I said with a whole new attitude and a genuine smile.
"Been working out a lot since I made the football team last year. Guess I hit a growth spurt at the right time." He said, stating the obvious. He was now 6' 2", 220 pounds of solid muscle with v-cut shoulders to a trim waist and tight ass! The pimples were gone, replaced by a handsomely rugged jaw line below a beautiful smile.
'Damn!' I thought to myself. This may not be such a bad summer after all. Kent helped me carry my stuff into the house and said to give him a shout if I needed any help with anything, he would be in the garage working out. He then smiled and left me in my room.
I must admit that I was now seeing him through a totally different set of eyes, which I didn't take off his ass until he was completely out of my bedroom. My mind was already racing as I felt a warmth between my legs. The attraction I felt was demanding attention, so I quickly changed from my jeans and sweatshirt into a pair of tiny running shorts and a matching sports bra. I then put on my running shoes and went down to the garage.
I opened the door to find that Kent had turned the garage into a well-appointed gym. Complete with dumbbells, a bench press, and lots of serious workout equipment. "Mind if I join you?" I asked. He was wearing only a pair of workout shorts with no shirt. Muscles already bulging from the completion of several sets of lifts. Seeing me in my outfit caused his jaw to drop, but he stammered "Uh, sure! Come on in!"
"I work out at school, but I don't know much about weights. Can you show me some exercises?" I asked as I pranced around the garage, giving him a full and unobstructed view of my ass, legs and tits as I bent over to examine various pieces of equipment.
He proceeded to explain various exercises and what parts of the body they targeted. He had me lay down on the bench press and do a set with just the bar, focusing on proper form and technique. Then we did a set of dumbbell curls for biceps and a set of triceps pushdowns on a cable machine. Next was back. "Dumbbell rows!" he announced, having me place my left knee and hand on a bench while grasping a dumbbell from the floor with my right hand. Instructing me to slowly raise the weight to my chest before lowering it back to the floor. He was standing to the side and behind me as he provided instructions. I knew my ass was clearly exposed. As I slowly raised the weight, I made a point to push my ass up and back, teasing him unmercifully. After doing a set of ten reps, I dropped the weight and sat on the bench. Kent quickly turned away, fumbling to find his shirt and quickly put it on as he stood with his back to me. I could see in the mirror that he had developed a massive erection and was attempting to hide it from me.
I smiled to myself, then let him off the hook by saying "Thanks for the coaching! I'm heading out for a run now." As I left the garage, I felt the wetness between my legs. Damn! I thought to myself, I need to take care of this and circled around to the back door and then headed for my room, intending to masturbate like crazy.
In order to get to my room, I had to pass Kent's bedroom. As I approached his door, I noticed it was shut but not latched. I could hear heavy breathing coming from the room, so I quietly pushed the door open just enough to see in. To my astonishment, Kent was laying on his bed completely naked furiously jerking off! I watched in amazement as he stroked the full length of his big cock. I know I should have walked away, but I was mesmerized by his growing excitement. A few more pulls and he shot a huge wad of sperm straight up into the air followed quickly by several more. His cum splashing down onto his midsection and running down the sides of his belly. He continued pulling on his cock until he was spent, then settled back into his pillow. I quietly made my way to my room and closed my door.
As I sat on the edge of my bed replaying the whole scene in my mind, I felt my juices running down the inside of my thighs. I also felt my nipples begging to be touched. I raised both hands to my sports bra, which I pulled over my head. I then started playing with my nipples. It felt so good and I was so horny that I decided to go for it right then and there. Standing for a second to peel off my running shorts, I quickly laid back on the bed. I again started rubbing my tits and pinching my nipples with my left hand as my right hand went between my legs. After a few long strokes across the length of my pussy, I went for my clit.
