It was a lazy Saturday afternoon, and I was watching my girlfriend get ready for her date, as usual. A few weeks ago, she had met this guy on tinder – charming, handsome, and most importantly, decently kinky. Since then, he had become somewhat of a regular, they met up once a week, usually on Saturdays, for their kinky little fuck-dates. Sophia had never really seemed like the type for rough sex or anything BDSM-related. But ever since we had opened our relationship, she seemed to be drawn to men who would treat her like a cheap little slut in the bedroom. I had only heard stories about her ‘adventures’ with Dylan, Sophia’s new FWB. He really seemed to be scratching this itch in particular, and whenever she came back from his place, she had this satisfied smile on her face for the rest of the evening.

Anyways, I didn’t try to think too much about their meetings, it was clear that this was more of a private thing between the two of them. At the beginning, I had been very curious about what they were up to, but Sophia had quickly informed me that he was not completely comfortable with her sharing every single detail with me, and that she would tell me stories if he gave her permission, which had only happened a couple of times since.

Still, it was hot watching her getting ready for him. She always packed a small bag full of toys, some dildos and vibrators she particularly enjoyed. And she always made sure to wear something nice for him. A few weeks ago, it had mostly still been summer dresses, but with the weather getting colder, lately her outfits had gotten a bit cozier. Today, she was already running late, wearing a comfy crop top hoody and hotpants, together with some thick and warm knitted thigh highs.

‘Are you running late?’ I asked her teasingly. I knew she was, the way she was frantically looking around for something.

‘I can’t find my phone’ she said exasperated. She was nervously running her hand through her curly red hair, and for a moment, her freckles were illuminated by the warm afternoon sun. She looked stunning and I felt myself getting hard with the thought that another man would absolutely ravage her in this exact outfit in a few minutes.

‘Do you want me to call you?’ I said, already navigating through the contacts of my phone. She sighed and nodded. A few seconds later, a faint sound was coming from the bag she had just packed for the night out. Relieved, she scrambled through her toys, finally lifting up her phone triumphantly. She smiled as she unlocked it, then her smile slowly vanished as she was reading her messages. First, she seemed taken aback, then she raised her eyebrows, slowly starting to smirk. ‘It’s Dylan’ she finally said. ‘He says, you’re welcome to join us today, if you want to.’
It felt like a gut punch. I did not expect that. At all. My mind went completely blank for a second. Then I was slowly realizing what this meant. ‘He wants me to join?’ I just reiterated what Sophia had just said.

Witnessing my timid girlfriend completely submitting to her FWB.

She was still reading. ‘Well,’ she explained as her smirk turned into a nasty little grin, ‘there are some conditions.’

My heart was racing, and I felt myself getting hard again. She looked so wonderfully naughty, in the slutty clothes that she had put on for him, telling me that he had the power to decide whether I could watch her get fucked by him. ‘Wha- What are his conditions?’ I stuttered.

Realizing how turned on I was by this, she moved closer to me, straddling my lap and slowly grinding my stiff cock through my pajama pants. ‘You seem to like the idea’ she whispered teasingly. ‘Finally getting to watch me on one of my little adventures with him…’

‘Ff-ffuck’ I exhaled as I was feeling the thrusting motion of her hips. ‘Maybe…’

‘Well,’ she continued, ‘it is up to you. But if you want to join us, he says you have to be okay with seeing me submitting to him completely… being his personal toy, his property, for the evening.’
I gulped as I felt my cock straining against my pajamas. I looked at her tiny frame towering above me, imagining how someone else would use her, treating her in ways that I could never do. I knew that I wanted to watch it, but me having to spell it out for her added an extra level of naughtiness to the situation. ‘What else?’ I asked gingerly.

She put her thumb into my mouth as she was grinding me, making me suck on her fingers. ‘He says if you want to watch me get used, you will have to do as he says. You will be his little bitch for the evening.’

I looked up at her with big eyes as she smiled down at me, now putting two fingers into my mouth as she was slowly rocking back and forth. ‘So, what will it be?’

I felt my cheeks burn red in embarrassment as I was trying to answer but was only able to produce some muffled sounds through her fingers. ‘Whhffaf-fllldf…’

‘What did you say?’ she laughed, grinding me faster. ‘You want to stay here and the afternoon with your PlayStation?’

‘FNo! I’vef sfaidf… Pfleaffse… I fwanft tfo fwatfch fyou’ I pleaded, sucking her fingers while trying to speak, humiliated that she made me beg for it like this.

‘Now say it again’, she said, finally removing her fingers from my mouth, instead taking them, and holding up my chin so that I had to look directly into her eyes. I felt humiliated, horny and more entranced with her than I had ever been in my life. ‘Please…’ I finally said, begging her. ‘I will do what he says. I want to watch you get used by him… I want to watch you submit to him, completely. And I will be his little bitch.’
