Next Room Over

My wife works nights at the hospital 4 days a week so I don’t see her often and when I do she is too tired for sex. So my sex life has been down quite a bit, been quite some time since I’ve head any relief. Two nights ago, my daughter had a guy over and I didn’t really mind. I went to bed and was watching tv getting ready to go to sleep when I heard something on the wall behind me. I turned the tv down and sure enough I can hear them clearly in the next room over, her bedroom, having very intense sex. I could tell they were trying to be quiet but given the close proximity and the fact that they were definitely not doing it in their bed but on or near her dresser against the shared wall and the fact that he was clearly giving it to her good, I clearly heard everything. I thought about saying something but I thought at least she’s getting some and I wish I was. After a few minutes it only got more intense and I admittedly got really aroused. The lack of sex is driving me crazy so I confess that I masturbated to them, matching their speed and aggression. They moved away so I had to really listen but I could still hear them. Finally after what had to be 20 minutes, I heard what definitely sounded like her boyfriend cumming so I let myself explode and man did I ever. It was so wrong but so hot. Last night I admit I thought about it and masturbated again thinking about it. So wrong but so hot
