I have this reoccurring fantasy; Me and some guy are on a couch and I'm straddling his lap slowly rubbing my lap on his. I continue this until I can feel his bulge against me. We then proceed to strip each other naked, and resume our position on the couch.

This time however I am rubbing my wet pussy on his semi hard pecker. Slowly up and down feeling him slowly growing harder against me. Feeling his pecker grow warm an stiff, rubbing from the base to the tip and back down. I then start teasing the tip, slowly pushing it into my opening but backing off jut before he penetrates I pull back up, and rub my pussy down his shaft.

After a little teasing I slowly push down until he just enters me. Then I gently bounce on the tip before slowly taking more and more until I have taken his whole pecker deep into my pussy. Then I roll my hips gently as I go up and down his shaft until I can feel him throbbing inside me, then I would fuck his brains out until he shoots his big hot load deep into my pussy.

This is my biggest fantasy, but I can't do it for a couple reasons.

1)I have a girlfriend

2)I don't want to get pregnant.
