"Wow." I said to myself as I stared out the window. The sight in front of me was one to behold. My older sister's best friend, Sara, was lounging by the pool in her green bikini. She was wearing large, black sunglasses and her long, brown hair was resting on her lightly tanned shoulders. The thin material of her bikini top was barley wide enough to cover her firm, round 34B breasts. I was pretty far away, but I was almost positive that I could see a little bit of her bush sticking out of her bottoms. My sister, Karen, was sitting next to her, but I had no interest in looking at her.
Karen had invited Sara to spend the weekend at our house while my parents were gone. Karen was back home on summer break from college and I was out of high school for the same reason. It was my senior year and I had just turned eighteen a few weeks ago. Karen and Sara were both twenty. I had always had a thing for Sara. She was so fucking hot and seeing her long, sexy legs and perky, firm breasts lying by the pool had never failed to give my a stiff erection.
Before I knew, I was rubbing my cock through my jeans as I watched Sara apply sun tan lotion to her chest. I was getting really hard now and I knew I would have to... relieve myself pretty soon. I was just about to head up to my room to finish up, when I heard a voice behind me.
"What the hell are you doing, Carson?" Karen's voice rang. She must have gotten up and used the sided door without me noticing. I pulled my hand away from my crotch and looked back at her.
"Nothing." I lied.
"You were watching Sara, huh?" She laughed and my face turned red.
"No!" I retorted. " I was just watching the sky."
"Whatever, freak." She rolled her eyes and went back outside. I sighed. That could have ended much worse, and I was very relieved that it hadn't. My cock as straining against my jeans still and I gave Sara's beautiful body one last fleeting look. I knew I couldn't hold out any longer and I ran up the stairs to my room.
When I got up there, I started to fiddle with my belt buckle. I cursed the fact that I had worn a belt today. I should have expected that I would be jerking off at some point that day. Anytime Sara was around, I couldn't help myself. My cock ached for her and that just couldn't be helped. It didn't help that I was still a virgin either. I spent almost every night fantasizing about how a pussy would feel around my 8-inch long member. I had been close to experiencing it once, but my then girlfriend dumped me before we fucked. I had spent a few nights thinking about her while I jerked my shaft, but most nights it was Sara's perfect ass that was on my mind.
I finally dropped my pants and my boxers, unleashing my fully erect shaft. It was pointing straight up at this point and seemed to be staring at me in anticipation. I couldn't wait any longer. I grabbed it and laid down on the bed. I managed to wiggle out of my t-shirt as I began to stroke my cock. My eyes were clamped shut as I pictured Sara. In my mind, she was fondling her pert tits and pinching her hard nipples, while licking those sexy full, red lips of hers. As I stroked, I could feel that oh so familiar tightening in my balls. I started to massage them while I stroked my cock and kept fantasying.
"Mmm Sara" I moaned aloud. "
"Oh!" I heard a voice and my eyes flew open to see Sara staring at me, wide-eyed.
"Oh... um" My hands fell from my crotch, but my penis was still hard as a diamond. I looked at Sara with horror in my eyes. Sara stared back at me with a strange smirk on her face.
"So, you do think I'm attractive, eh?" She asked in her innocent voice. She leaned in the doorway and my eyes fell to her breast that her still incased in the thin fabric of her bikini top. Were her nipples hard?"
"I'm sorry." I said dejected. "I... I didn't...." She just smiled at me.
