2: Show Time
It was several days after me and my sister Kate had our walk in the woods. Kate was still visiting and although she hadn't given me another treat like the one in the woods we had been behaving differently around each other. When mom had left for work in the mornings me and Kate would strip off and spend the day walking around the house naked, if the weather was nice we would sunbathe naked. Usually I would get erections from seeing my sisters beautiful naked body, I never tried hiding my erections from Kate but I would go to my bedroom and masturbate over the thought of her.
I woke up in the morning and went downstairs into the kitchen. Kate was already in the garden sunbathing, mom was still home so Kate was wearing a red bikini that clung tightly to her body. Her bikini had string ties holding it to her body and it showed every curve of her body beautifully. My mom was in the kitchen getting her things together for work. Normally I never paid much attention to the way my mom looked but since my experience with Kate I had been looking at her very differently. My mom was in her early forties but she looked ten years younger. She had a slim toned body, her dark brown hair came down to her shoulders. Her breasts were much smaller than Kate's but looked very firm and pert. She was wearing a pale blue blouse and a black skirt that stopped just above her knees, she had a pair of black stilettos on that made her bare legs look amazing. It was her normal work clothes but I hadn't noticed how sexy she looked in them before now. Mom gave me a kiss on the cheek and left for work, as soon as she had left I went into the garden to see Kate.
"Has mom left now?" Kate asked as I went outside.
"Yes, she just went." I answered.
"Great it's about time. I don't want to get tan lines." Kate then stood up and quickly pulled off her bikini, dropped it on the floor next to her and laid back down to sunbathe naked. I had seen a lot of my sisters naked body in the past few days but I never tired of how beautiful her large breasts were, I loved the dark triangle of pubes above her pussy. I got naked as well and sat with my sister talking, It didn't take long for me to get an erection but I didn't run off straight away. I stayed with Kate talking with my erect cock fully on display to her. Kate noticed my state of arousal and she took a good look at my cock.
"It's always getting hard but never gets bigger does it little bro." she said with a giggle. My penis was quite small and although me and Kate had an unusual relationship she was still my big sister and she often teased me about it.
"I like a nice big one between my legs." As Kate said that she grinned at me and gave her pussy a gentle stroke. That was enough to push me to the edge so I got up intending to go to my bedroom for a quick wank.
"Where are you going?" Kate asked.
"Where do you think." I gestured to my hard-on as I said it.
