It all started when my gf was riding her dildo while she made me watch,I instantly thought of her riding someone else.

From that moment every time she was bent over giving me head I would imagine her being fucked from behind by another man.

We started watching porn together and I loved how wet she got looking at the big cocks on the screen and I told her I wished she was the woman in the video.she was a bit shocked at first and wasn't sure if I was being serious.

When we watch porn I never imagine I'm fucking the girl I always imagine my gf is in the video.

She now finally realises thats what I want and she now admits she'd love to be getting all that big cock (especially big black cock).

Her pussy gets so wet while she makes me pleasure her with my mouth while she tells me she needs those big black cocks and tells me how much bigger they are compared to mine.

She often makes me wear her silky pants and makes me use her dildo on myself,all while wishing she was getting pounded by big cocks.
