Ever since my totally erotic encounter with my younger sister Amy, in the bathroom the other morning (story “Sister’s Stay), I've been completely obsessed with her beautiful 19-year-old body. My sister looks very similar to the playboy playmate, Suzi Simpson, if you've ever seen her great body. She has sandy blonde hair with the same color light blonde haired pussy and grapefruit size tits with very large nipples. I'm a leg and ass man but my sister's breasts are a perfect sight to behold. Now, I will add that her legs and sweet looking butt are pretty fine too.
Since that morning when we first had sex together, I've been taking every chance I can to see her body. From my bedroom, I have a full length mirror on my bedroom door and when angled properly, I can lie on my bed and see right into her bedroom. I've caught her several times undressing before bed as I lay in my bed stroking my cock to the view I get each time. She wears some real hot and sexy lacy type bras and panties. Sometimes she undresses and then comes into my room and slides into bed with me, sometimes she pull her nightshirt over her head and goes to bed. I've had a constant hard-on since that morning but she's happy I'm always ready for sex. One night, after she turned out the light, I could tell she was getting herself off just by the sounds. I creamed the sheets of my bed just listening to her.
My bathroom has a louvered door with one of the louvers missing so I can watch as she takes her bath. She likes to take hot baths over a shower usually. One time I was watching through the door and she started to massage her breasts with her soapy hands. The sight of her tits and nipples sliding between her fingers was too much. I pulled my cock out and began stroking my cock to the sight of my sexy sister before my eyes. Her nipples were standing erect as she pulled them between her fingertips. Her right hand slid down her body, across her tight abs following that sexy vee right to her sweet pussy mound. She began to work her pussy with first one, then two and three fingers, rubbing her clit faster and faster. As she reached orgasm, she arched her back and her body shuddered in lustful bliss. I came at the sight of her orgasm and couldn't help but let out a groan as I shot out another hot load of cum for my sexy sister. She looked at the door and just smiled as she knew I was there and put on a show for me. Amy motioned for me to enter and she asked, "So Ron, did you enjoy the view?" “Amy, you are the sexiest woman I’ve ever seen.” I replied back. “You’re not so bad either big brother. I just love that hard thick cock of yours.” She said seductively. She then slowly stood up and I enjoyed the view as the soapy water and suds glided down every smooth ripple and curve of her sexy body. Looking deep into my eyes, she slowly brought her hands up and cupped her large soft breasts. She smiled devilishly as she rolled her swollen nipples between her fingers and pulled those soft white mounds of breast flesh together for me to see. God, she was so fucking gorgeous! She turned her back to me, put her hand against the shower wall, arched her back and pushed her sweet ass out to me. Her skin was glistening wet with small patches of suds on her perfect butt cheeks. Her sexy thong tan-lines were very hot and sexy looking but nothing compared to the completely erotic expression on her face as she looked over her shoulder, her sexy eyes penetrating my very soul and sending jolts of sexual energy to my rock hard cock once again. I quickly shed the rest of my clothes and entered the tub grabbing her sexy hips, sliding my hard thick shaft up between her slick wet thighs until it grazed her wet pussy mound from behind. “Ummmm yes baby, that feels very good.” She moaned as my hips moved back and forth, my cock gliding just under those soapy wet pussy lips. She took her right hand and reached under, softly grabbing my hard shaft and pressed it hard against her opening, spreading her labia as her juices mixed with the suds. My swollen cock head was sliding across her wet opening, just touching her erect clit on each forward pass. “God Ronnie, that is really getting me hot.” She panted as we picked up the speed slightly and she pressed my cock harder into her. Suddenly she arched her back a bit farther which changed the angle just enough as my cock hit her opening, spread her pussy lips and slid right into her hot waiting pussy. In one slow move, my shaft slowly slid all the way in, her pussy muscles squeezed and pulled me into the hilt.
