One night I couldn't fall asleep right away... And after about 15 minutes of just laying there I heard one of my parents get out of bed and quietly shut the door and lock it. I instantly heard kissing and some movement on the bed. Then I hear my dad take off his pants and I heard him say 'Suck it honey'. Then I heard sucking noises and I heard him moaning softly. (at this point I'm super hard and started to jack like crazy).
Then my mom said 'lick it hard this time'. And within and few minutes I heard her start to moan a little bit. Then within a few minutes I heard my dad ask 'you almost ready'? And my mom whispered 'yes honey fuck me'. I almost cummed as soon as she said that.
I then heard someone get up and open the closet door. And my dad said 'We're out of lube'. And she said 'there's more in the hall bath'. Then my dad unlocked and opened up the door and I saw his full erection as he walked by my room to get to the hall bath. Then he walked back in and said 'I got it'. Then I heard more kissing and then I heard the lube bottle open and then I heard movement on the bed again and then I heard squeaking of the bed as my dad started to pound her. She started out by moaning just a little bit but then started to scream as she said 'harder honey, harder'. Then I heard noises as he was pounding her and she continued to scream 'harder, harder'! I then got out of bed and walked near their door for a better listen and to jack more.
My dad then began slapping her ass. And he started to moan pretty loud and yelled things like 'oh FUCK YES'. My mom then yelled 'I'm cumming, keep going'! He then screamed so loud it could wake neighbors and she screamed 'YES, YES, YES'! I was even out of breath at this point.
He then sped up even more and then yelled 'OH, SHIT' and moaned a lot while running out of breath... she then said 'Your cum feels great'!. and my dad kept moaning and after a few minutes sighed 'oh god that felt great'... In the mean time I cummed like crazy all over the floor. I can't wait until they fuck again.
