In her pussy

I can't hold it any longer. I pull her down and hold her hips against me as I thrust my own hips upwards. I feel her vagina trembling as I throb and shoot inside. As I orgasm, I imagine Marie vividly. I can see her cock inside my girlfriend's pussy, pulsing like a tentacle monster, filling her with sticky, white cream.

"OH GOD! Did she fill you like this??"

"Yes!! She shot so much more inside me!! Please give me all your seed!!

I let out a huge load as we both moan. She shivers as I embrace her, climaxing too. We remain immobile for a long time, just enjoying my cock getting squeezed by her inner walls..

"Oh, babe... That was... Amazing..."

"Yes... I love you, sweetie."

We kiss.
