Lately my wife has been fucked twice in whitch she was kind of "used". And by that I mean she had (kind of) consented sex but the guys just shoved their dicks into her and fucked her untill they came. Not much caring for her "needs". At those moments she indeed felt used. But to get fucked (hard) in that way turned her on afterwards. So we decided to dig into her submissive side.
Saturday afternoon we started with mild bondage. I tied her up on the bed spread eagled, put a blindfold on and started teasing and tickling her with a (clean) duster, queezing her tits, fingering her pussy and feeding my cock to her mouth. All went well and we both got very exicited.

And then my MIL saw us...

She lives close by and decided to drop in llike she regulary does. We'd forgot to lock the backdoor and also the door to our bedroom was open. My MIL has a slight hearing problem but she'd heard our voices from coming from the first floor and innocently thought we were just talking to eachother. And we hadn't hear her coming in

She stood in the door of our bedroom and the look on her face when she saw us... Her daughter tied up spread eagled to the bed. Her son in law snaked with a hard-on next to her. And from where she stood she looked straight into my wifes' pussy.
I guess she stood there for about 10-15 seconds trying to grasp the situation she's stumbled into, before it dawned to her. She said something like "Oh my god... You're naked.. And... Oh.. Eehrrr... I'm so sorry..." She turned around and left our house.

Needless to say the mood was over. Although my wife hadn't seen her, she'd defenately heard her mothers' voice and she was really embarressed. After I'd untied her she put on her clothes and rushed after her mother. It all ended up fine. My MIL was quite shocked, but after some clearing up from my wife they apparently had some laughs about it.
Later me and my wife also had some laughs about it. But we'll make sure we locked the backdoor from now on.

Just to get a visual idea of the situation. Below is a picture I found on the interwebs that kind of resembles the view my MIL had.
