The warm summer air was blowing around the yard. My mother in law was talking to me about some useless garbage that I really didn't care about. My cock was hard in my now untied shorts. My sister in laws young hard ass was facing me, while she floated calmly half on an inflatable air mattress. I nodded and agreed with the mother in law in an attempt to appease her and make her go to work and leave us alone.
My sister in law was in one of those great moods where she was horny and perverted all at the same time. I loved it because I was usually the recipient of her horniness. She had this knack of making me hard with just a glance. Her big C cup tits bounced around as she turned me on. She had already flashed her ass at me a couple of times in the pool and she was aware that I was rapidly joining her in her amorous mood.
I loved to remember the times that we had been naughty together and from what I read in her diary she enjoyed them too. She had spent several nights sleeping down stairs in my apartment before today, but I easily remembered I time when I had pushed the limits.
After a long afternoon of swimming and playing she joined me downstairs for pizza and chips. We did this on a regular basis as my little treat for her when her mother was working. We had encountered so many things together that I felt weird when she wasn't there. Tonight was different from all the others. Tonight she had worn her panties. Usually she chose not to. I was taken aback, but decided not to push the issue. I got changed into my usual attire, loose cotton shorts and a light t-shirt. After the food she popped in a movie for us to watch. Now she had already seen quite a few movies before she should have. So the choice of movies we could watch together was almost unlimited. She had seen more bad movies before she was allowed to than I had all together. As the credits started she jumped onto my lap and snuggled in. Her hands were dangerously close to my cock as it lurked just underneath her.
On several occasions she took the opportunity to graze my cock with her hands. She gently brushed against the head of it in a feeble attempt to fondle me. I, for one, was not even remotely interested in preventing her from grabbing hold of it and doing what ever she wished. In fact, I was always hoping that she would feel the desire burning so deep inside her that she acted on her own and made the first move. For her to be overcome with such emotions that were so strong that she couldn't control herself is something that had become a burning desire of mine. I was not so fortunate.
I made every attempt to lead her into a sexual situation but she resisted them all. I repeatedly rubbed my cock against her in an attempt to arouse her. I flashed my hardening cock. She ignored it. I was getting horny trying to get her turned on. I tried putting my hands on her leg and rubbing it. This usually started to get her going, but not tonight. I was getting frustrated, but still horny.
When the movie was over it was pretty late and she was complaining about how tired she was. She asked if she could crash on my couch and I readily agree. I went into my room and left the door slightly open while I changed for bed. I had positioned the mirror so I could she her in the living room. My mood was suddenly uplifted. She was watching. I took my time and allowed her to see everything I have. She watched my act for a few minutes. I was getting hard and my cock was starting to rise. I wondered if tonight was her attempt to drive me crazy and that all my advances where being refused despite how horny she was getting. I reached down and gently stroked my cock a few times with my back to her. I turned slightly in an attempt to show her more. I left my hand on my cock and continued to stroke when I knew she could see everything. I heard her gasp and glanced into the mirror. She was sitting in my chair looking straight at my cock. Her hands had disappeared into her pants.
The left hand was holding onto the waist band of the pants and holding them away from her body as the other worked furiously on her aching pussy. Seeing this, my cock easily became consumed with the idea of fucking her hard and often. No more rubbing or flashing, I wanted full deep penetration. I wanted to pull down her pants and force my face deep into her love box and eat her until she came again and again. I wanted to feel the lips of her shaved pussy dance with mine while my tongue flicked gingerly at her clit. I wanted to let my hands roam all over her ass and around her rosebud. Fingering her ass as I ate her was such a turn on. I released my cock as I was stroking it vigorously and was about to shoot my load all over the carpet. I glanced up at the mirror for confirmation of her passion and she was gone.
She wasn't watching anymore. I wondered if she went out of sight to finish herself off. I quickly grabbed my housecoat and headed for the living room. There I found her, but as I expected or hoped. She was pulling out the hide a bed from the couch and was going to make the bed. She looked up at me and then down at the obvious tent I was forming in my housecoat. She turned her back to me and continued to avoid me again. I was stunned and confused. Even worse I was still very horny. I didn't know what to do. I stood there stunned. Probably with my mouth hanging open. She looked at me for a moment and stepped past me and went to the bathroom. She locked the door behind her as I heard it click behind her. I went into my room totally frustrated and stunned. I sat on my bed with my cock still semi hard and dying fast. She came out of the bathroom and headed to the coach. I begrudgingly crawled into bed.
I lay in bed with the lights out for what felt like and eternity. Actually three hours had passed and I was still awake and still incredibly horny. I thought maybe if I went to the bathroom and jerked off I could release some strain and get some sleep. I headed down the hall to peak in on her before I did my deed. There on the couch was my sister in law, spread eagle and her shirt pulled up with her nipple peaking out. I walked into the room as quietly as possible and approached the bed. She lay so still and I was so gentle. I pulled up her shirt to around her neck. Both of her beautiful tits were laying there for me to see. I watched them for a moment before I got enough courage to touch them. Gently I rubbed my finger tips over the soft skin of her breasts. I paused for a moment as I touched her nipple as it reacted to my touch. The stimulation was appealing to her as her nipple started to rise. I watched it as it moved. Concentrating on one I had an idea. I pulled off my housecoat and stood inches from this vixen with my hard cock in hand. Part of me now says I should have fucked her, but I was in a teasing mood. I rested my cock on her nipple and gently rubbed it against her.
In a swirling motion I gently fondled her nipple with the aching head of my cock. I was incredibly turned on at this. I had never had skin on skin contact with her. In my excitement my cock started to ooze my pre-shot. Surprisingly, I had a great deal of liquid leak out of my cock. I wasn't sure if I was going to be able to stop cumming all over her tits. This still wasn't a bad idea. It would satisfy my fantasies, or at least some of them. I pulled back as she started to move. The last thing I wanted was for her to wake up and send me packing with no satisfaction.
She settled herself down, but covered up her greased tits with the blanket. Her rolling over had placed her head dangerously near the edge of the bed. Her mouth hung slightly open and facing towards me. The idea over took me. I didn't even think about it. I stepped up to her face and placed my ridged cock to her lips. I wiped the pre-shot from the head of my cock onto her lips. A big drop of juice dripped off of her upper lip and landed in her mouth. I paused for a moment to see her reaction. Her mouth closed and she swallowed it down. Her tongue darted out of her mouth and licked her lips as it looked for more. More than willing to oblige, I rubbed my cock against her lips again. I held my cock against her luscious lips and awaited her return. She did not disappoint me.
