That fall Caitlin’s brother Sean went off to college at Michigan State, leaving Cait and Megan with only each other to satisfy their desires – and me, of course. They had gotten such a kick out of dressing me up as a girl that they decided to do it again, and this time they would take me shopping for an outfit of my own. As we strolled through the mall, it felt strange and exciting to feel the eyes of every boy tracking u...

The morning after our day at the lake, I was half-convinced I had dreamed the whole thing, from the feel of Cait’s amazing tits to getting a blowjob from my stunning big sister Megan. But at the breakfast table, Megan gave me a lewd smile, which of course our parents didn’t notice, and started playing footsie with me under the table. I knew my pecker was in for another day of adventure. Just watching her eat her breakfast...

Caitlin climbed up on my shoulders as I crouched in the water, and when I felt her hot inner thighs on either side of my neck and her firm belly pressing into the back of my head, I began to get hard. Chris hopped astride Megan, and when the two riders began to shove each other, it was a great pleasure to feel Cait’s thigh muscles flex and hear her grunt with exertion. Even holding onto her little feet as she wrapped her...

One weekend we drove to Chicago to visit Dad’s parents, leaving Friday evening and riding late into the night. Caitlin and I rode in the back seat, and after a while Cait pulled a blanket over herself and stretched out, resting her pretty head on my thigh. I ran my hand affectionately through her velvety close-cropped hair, and the sensation, together with her warmth against my thigh, began to turn me on. When she rolled...

One day the next week I picked the girls up at the high school. I had brought a football and proposed walking over to the soccer field and tossing it around; Megan was dubious, but Cait said, with a twinkle in her eye, “Aw c’mon, babe, it’ll be fun. We’ll make it worth your while.” The three of us played keep-away--tackle keep-away, that is. Even if she managed to catch the ball, Megan would panic when she saw Cait runnin...

One warm spring day, after Cait got home from school, we went for a walk in the woods. I enjoyed letting her get a little ahead so that I could watch her tight ass pumping with each athletic stride. We walked until we came to the nearest lake, then sat on a flat rock, taking our shoes off and cooling our feet in the shallow water. I sat close enough to feel the side of her thigh against mine, sensing the muscles tense whe...

I always thought my little sister was pretty hot, but my fantasies began to become a reality when she was sixteen, a junior in high school. I was two years older, still living at home and working at the local hardware store to save money for college. She was five-foot-three with dirty blonde hair cut short enough to stand up, nerdy hipster glasses, and full soft lips. Her narrow hips gave her a boyish figure that was beli...
