About 8 years ago my sister broke up with her boyfriend and needed a place to stay. I had a 2-bedroom house so I offered a room to her and she accepted. Her name is Amy and she agreed to stay only until she could save up enough money and find her own apartment.
Let me tell you about my younger sister, she is about 5 ft. 4, weighs about 115 pounds, curly sandy blonde hair, measures around 36-23-35 and is about 10 years younger than me. Even though she is my sister, I always wondered what she'd be like in bed. Her ass is perfect and her tits are simply the best I've ever seen. She has nipples about 1/2 inch when erect so it's easy to tell if she's cold or aroused. She always has a dark tan and super sexy tan lines which I've caught glimpses of on occasions.
I've seen her in this red, white & blue one-piece bathing suit, which is very thin and does not leave much to the imagination. She must have removed the liners as you can clearly see her nipples and the small tufts of pussy hair through her bathing suit. She could easily be a model if she tried but at 19 years old she wasn't sure what she wanted yet.
She is my sister so I kept my fantasies to myself and gave her the space she needed to get over the break up with her boyfriend. After about 3 weeks, I got up one morning and staggered to the bathroom with a morning hard-on needing to take a leak. As I entered through the unlatched bathroom door, still half asleep, I got a surprise never expected. My sister was in the tub taking a hot bath, leaning back, with a washrag over her eyes. I was fairly quiet entering the room and I just stood there for a minute feasting my eyes on her young beauty.
This was my first chance to see my sister's naked tits and her neatly trimmed pussy. The curves of her stomach and hips all coming together at her sweet pussy. I stood there taking in all the sweet curves, from the firm round globes of her breasts down to the sensual turns of her smooth sexy legs, all shimmering from the wetness of the hot water which enveloped them. I could just see the lips of her cunt slightly showing through the bubbles and water. Man, I tell you, my cock felt like it grew 2 inches.
All of a sudden she realized I was there and I came crashing back down to reality. "Ron, what the hell are you doing in here?" and quickly tried covered herself with the small washrag the best she could.
We only have one bathroom and I explained I had to piss real bad, apologizing for not knocking but stating the door wasn't latched. To my surprise, she told me to go ahead and go but make it quick. As I stood at the toilet, with my back to her, I could see her in the mirror above the sink. Her tits were still covered by the washrag but I could still see the firm round sides of her boobs. After several minutes, I was finally able to relieve myself even though my cock was hard as a rock, it just took a little longer to go.
As I stood there finishing, holding my 7 inch hard cock in my hand, I found myself again looking at her tits noticing she removed the wash cloth. Her nipples were swollen and looked like large pencil erasers pointing out. There I stood with a raging hard-on, looking at my sexy sister through the mirror. My heart was pounding with excitement. After about a minute of watching those gorgeous breasts, I noticed her right hand was gently massaging her clit, barely visible under the suds. Without realizing, I was slowly stroking my hard cock, mesmerized by the beauty of my sister as I gazed upon her in the bathroom mirror.
All of a sudden she asked in a sexy tone, "So what's taking so long over there?" not seeing I was watching her in the mirror.
I caught my breath, as my knees felt weak with lust boiling in my body and slowly turned to face my sister. My shorts were at my knees and I held my seven-inch hard-on in my hand. This was her first real good look at my hardened cock and her eyes were locked on it.
All I could say was, "Amy, you look so damn good I can't get my cock to go down".
By now, the head of my cock was purple with blood and throbbing in my hand. Her next reaction really caught me off guard as she slowly slid up in the tub allowing me full view of her super hot sexy body.
With this glazed look in her sexy eyes, she looked into my eyes and said "It seems like my horny brother might need some help with that?"
I stood, knees trembling, in disbelief, as she slid up in the tub onto her knees, her face just inches from my cock. She was looking me in the eyes and without saying another word, her gorgeous lips touched the head of my cock. I couldn't believe my eyes as she slowly slid those soft pouting lips over my shaft, watching my cock head disappear, until she had almost the whole length in her mouth. My sister pulled back, holding the head of my shaft in her moist hot mouth.
She then began to swirl her tongue around slowly and began a slow in and out motion. As her wet hands held my hips, her head began to slowly swivel from side to side as she moved my cock in and out of her soft mouth. As if that wasn't enough, she began to moan as she did this, sending vibrations through my ready to explode cock.
After about 30 seconds of that I said, "Amy, I'm going to cum, Aaaahhhh", and she quickened the pace.
