Sunbathing with my stepsister

Wednesday morning. I woke up to see the summer sun shining in through my bedroom window. Bright and early. Well, not exactly. It was 10 a.m., and I was enjoying the laziness of summer break between my sophomore and junior years of college. I was back at home living with my mother and stepfather for the summer, sleeping in as they were off at work. The only noise in the house was the hum of the central air conditioner. Seemed I had the house to myself.

I got up and showered to ready myself for another day of relaxation. As I got out of the shower and toweled myself dry, I glanced out the bathroom window overlooking the back deck and saw that I was not alone. My stepsister, Christine, was walking through the back yard, onto the deck. She was staying with us for a couple of weeks until she could move into her new apartment. She was wearing running shorts, a white t-shirt, sunglasses, and a baseball-style cap. Seemed she was coming back from a jog.

At twenty seven, she was seven years older than me. She had just retired from playing for a WNBA team, but she wasn’t the stereotypical female pro-basketball player. Christine was tall for a woman, a shade taller than me. She was very attractive with long black hair and beautiful green eyes. Her body was fit from years of playing sports, but still very feminine at the same time.

I watched as she walked across the deck to the door leading into the house. The sounds of the door opening and Christine’s footsteps across the rooms downstairs carried up to my perch by the window in the bathroom. Soon she reappeared on the deck with a bottle of suntan lotion, a beach towel, and a book. She was now barefoot, but still wore her running shorts and t-shirt. Her hair was tied back in a pony tail. I watched intently as she evenly spread the towel out on the chaise lounge chair.

To my surprise, she slid her thumbs under the elastic waistband and pulled her shorts down her fit thighs. She bent down to slide the shorts down past her knees and step out of them, tossing them aside. She wore no panties underneath the shorts, only the liner of the running shorts and I could see the well-trimmed triangle of her black pubic hair. She removed her sunglasses and grasped the bottom of her t-shirt, pulling it up over her head and dropped it onto her empty running shorts. She did the same with her sports bra, revealing her perky breasts and pink nipples.

I felt like Judge Reinhold from that famous scene in Fast Times at Ridgemont High when he fantasized that Phoebe Cates took off her top as she got out of the swimming pool. But, instead of it being a fantasy, Christine was really nude. I gasped audibly when she stretched and arched her back to pull the bra over her head and bare her beautiful breasts. I could feel myself becoming aroused watching my stepsister from the bathroom window.

Christine picked up the bottle of suntan lotion and began spreading it over her fit body. She started at her ankles and spread the lotion up her shapely legs, working her way up her tone belly to her round breasts. I was starting to breathe hard as she spread the oily lotion over her breasts. They bounced up and down as she rubbed them with the palms of her hands.
