The urge to drink water woke me up in the middle of the night. It wasn't actually very late, but because I had slept early, it felt like it. I slowly stood up from my bed and carefully opened the door, got out and closed it with the utmost care, making sure to not wake anyone up.
The house was dark, but the small lights at the end indicated me toward the stairs. Slowly walking, I climbed down the stairs and reached the kitchen. The water was filled up on the counter. After quenching my thirst, I began walking back.
But as I was walking back to the stairs, a weird sound caught my attention. At first, I thought I was just dreaming but the sound kept on coming back. It was like a cry, sometimes low, sometimes loud.
'Maybe I should go check it out. Someone might be in trouble.'
I wondered as I started to follow the direction of the sound. It was likely coming from a room on the same floor as the kitchen. The sounds became more clearer and louder the more I walked in their direction.
After just a while of walking, I saw a room whose lights were still on. As I went near, the door was also open but not fully. I tried to peep in to see what was going on. And the moment I saw what was going on, I was left in complete shock.
"Mmh! Aah!" It was Yui's mother, Saikawa-san, masturbating. "Mmhh!"
She was sitting on her bed, completely naked. No clothes at all! Her legs were in an M shape. Her right hand, with the middle two fingers, slowly going in her pussy, circling it, massaging it, and pleasing it in every way possible.
While her left hand, groping her breast, moving and squeezing it firmly. Her index finger playing with her pink nipples, which were completely aroused.
"Mmhp! Mmh! Oh yes! Ah!" all I could hear were her moans in the silent house. The more she did it, the faster she moved. Her fingers were thrusting in and out faster everytime.
'As a single woman in her late thirties, this might be her only way of pleasing herself' I thought.
Then she did something unexpected. Her removed her fingers from her pussy, which were soaking wet with her juices and started licking them, putting them in her mouth and sucking on them. Then put them back down there and started going even faster.
With every thrust her body moved to the vibrations. "Ohh! This feels so good!" she lied to her side now, still going. It felt like she was reaching her limit.
Her body shivered with every thrust. Her thighs first squeezing her hand, but then opened up. I could see everything going on down there.
"Oh! If I keep doing this, I am going to-" she pushed her fingers deep inside one final time.
"Cum!"
And with that, she was done. Her tongue sticking out, her body completely covered in sweat. Before she started to clean up and sleep, I managed to escape safely and return to my room.
"I truly witnessed something else today!" I said to myself as I went back to sleep, preparing for tomorrow.
