Eaten by my sister-in-law.

In '75 I was living in Ilhabela, in a small chalet by the sea. One day one of the sisters-in-law (there were four sisters), Rita, separated from her husband and came to live with us. I was faked, the chalet was compact and she had two small children. But life circumstances are life circumstances, I had to accept.
A few weeks after my first wife traveled to São Paulo, Rita was taking care of the house, making the food, that sort of thing. During the day she was on the beach, a reduced bikini more showing and emphasizing that hiding her shapes. Sunbathing, belly, was a temptation in the form of a woman, I forced myself not to think nonsense and not to look, so as not to pass the desire.
At night I was watching TV when she came up the stairs. The only room was on the mezzanine, the TV was in front of our double bed. I wore only my pajama pants, closed by a cord, the bracelet without buttons, and I was covered by a simple sheet.
Rita wore a discreet, long, dark-blue sweater that reached down to her feet, nothing provocative.
I locked the door downstairs.
Even a little counterfeit, I agreed, without thinking of the scope of what she had said. Below were her children sleeping, behind the said locked door.
Rita sat on the floor by the bed and watched TV in silence, and things started to get boring.
There's no reason for you to stay on the floor, I just ask that you don't say anything to your sister.
She was a little reluctant, but eventually she agreed, and we started to watch a late movie, the tiredness came, my day had been long, and under the backlight of the camera I unexpectedly saw that my dick was perfectly delineated by the sheets, revealing, I turned to the side to disguise.
- Watch TV as much as you want, Rita. Lie down, be more comfortable <unk> I offered, without any second intention (or first, your wise ones). <unk> I'm going to sleep, turn it off when you go to sleep, good night.
She said good night, lay down beside me, covering herself discreetly with the sheet, far away from me. I tried not to think of anything, my eyes began to weigh, before long I was entering the so-called world of dreams.
I awoke confused, feeling her hand on my chest, the TV was on, Rita seemed to be asleep, I stood still, undecided whether to take her hand off or leave it where it pleasantly was, and that's when I noticed her hand moving down a little bit, I even wondered if it had really happened, maybe it was a muscle relaxation caused by her sleep.
Once again I felt his hand move slightly, coming close to my navel, I pretended that I was asleep. In the next movement the hand stopped on the lace of the cord, it froze as Rita pulled it and released it gently. A little more and, this time, it was his fingers that extended slowly until they touched my cock that was laughing.
For a while the tip of her fingers were just resting on the throbbing side of my dick, as if assessing whether I was really asleep. I was petrified (both ways). And then, carefully, she tenderly wrapped my cock. She held it for a few moments, feeling the size and thickness, starting a few slow movements back and forth. Semi-closed eyes, I realized that the sheet was waving over Rita, she was masturbating at the same time as hitting me with a fist. She almost lost control of the situation when her hand accelerated on the stick and felt her body tremble by my side as she went.
Rita then let me go and stood still for a while. She looked at me attentively, making sure that I was "asleep". Then she got up and left the bed.
<unk>- No, don't go away <unk> I begged in my mind. <unk>
But she wouldn't. She took off her long sweater, leaving only a small one that was under it (it would perhaps be the old baby doll) and took off her tiny panties. In the meantime I had turned in my "deep sleep", lying on my side, facing her.
Rita lay down and stood still. Less than a minute later I felt her hand reach for my cock again, making sure it was still stiff. She then turned also to the side and, with her back to me, brought her delicious body closer to mine.
Incredulously, I felt Rita drive my throbbing stick into the appetizing crack and insert the tip of the header from behind into that intense wet heat.
She stood still again for a moment, the contractions of her opening making themselves felt in my dick that yearned to get into that little bottle that wanted me. And then she slowly pushed her ass against me, making the cock penetrate little by little into her fiery entrails. She began to move slowly on my dick, making it go and turn deliciously, I could not bear it any longer and I projected myself once again against her, making my dick stick to the bottom.
I embraced her, wrapped her breast over the sheet, and began to stock up on all the anxiety and excitement she'd given me, the fuck coming and going deliciously, and almost the next moment she was enjoying herself vigorously, a violent orgasm shaking her body.
Without saying a word, I pulled the throbbing cock out of her hot body, threw away my pajama pants, left her completely naked, and placed myself between her open legs. I leaned over her, kissing one of her breasts as I passed, and Rita embraced me with one hand and, with the other, led my cock back to the sweet little bottle.
We started fucking again with all the voluptuousness that we were into. My cock came and went tirelessly in its tight little mouthpiece, which sucked me with a sigh. She must have been very short of dick, because then she made fun of me for the third time, this time screaming, I covered her mouth with my hand so that she wouldn't wake up the children.
I kept savagely stocking her insides, and then she had her fourth orgasm and I deservedly splashed all over her, kept going back and forth until the fuck lost its rigidity.
I wiped her face with affection, and she went to take a bath, and then she came down and went to bed with her children, full and in peace, at least for that unforgettable night.
