Sneak in

As I saw her take off her robe, my dick hardened. My brain started to get hazy as I could finally see what that pervert constantly flaunted. I guess I wasn't thinking properly because I slowly moved my hands to the window and tried to slide it up. To my surprise it lifted with barely any resistance and without any noise. Must've been oiled recently, I guessed.

It was a windless night and quite a nice temperature so no one in the room noticed anything. I moved into the room silently and hid behind the curtain quickly. The curtain was this ornate one that went from the ceiling to the ground and was perfect to hide behind. But I was so close so I didn't dare peak out to quickly. I heard a loud groan and I took that as my opportunity to use my phone to check what was happening.

I saw my tutor blowing her husband in this red lingerie that accentuated her body. Her g-string that framed her fit ass that she worked everyday on, a garter belt with accompanying red stockings and a lacy bra that showed off her fantastic tits. She was bent over servicing his tiny cock and he was looking up into the ceiling, trying his best not to blow too early.

I peak out of the curtains, watching this spectacle in front of me in awe. Eventually, he grabbed the back of her head and pushed it down on his dick as he groaned out. She moved out and opened her mouth showing his cum and closed it, I heard a gulp as she swallowed it. She got up and moved towards the robe, she looked obviously disappointed. In fear of being discovered, I retreated into the curtains.

I heard a scuffle and I peaked out again, her husband surged up and grabbed her from the back. She looked shocked, must've been the first time he could do more than one round, I mused.

She was thrown onto the bed and he rushed to get on top. He quickly shoved his dick into her vagina and started to furiously move his hips back and forth. It was quite short thrusts but judging by the sounds he was making, he was enjoying it. I looked at my tutor and she moaned but it was obviously it was fake, her face looked bored.

With one last pump, he went full hilt into her and groaned out for the last time. He rolled over to the side and promptly started to snore. My tutor looked up towards the ceiling and her hand slowly snaked down to her pussy. Before she could reach her pussy a burst of wind blew through the still-open window. My heart dropped.
