Can he make me squirt?

I've always wanted to squirt, but nobody has managed it yet. I had almost given up hope when my girlfriends kept telling me that Mark had managed to get them to squirt. Now I've finally met him and just asked him straight away. So we made a bet straight away to see if he could really do it. After I've blown him, he fucks my pussy first before he lays me down on the sofa and tries his luck. Do you think he'll make it?
