Last part:
She finishes her blowjob and he begins to take her from behind without a condom. But after some time she stops him and wants to get one, he begs to continue without it, which she replies to with "No, thats not good" and like a good girl she is puts on the condom for him. And so they continue safe and standing, eventually moving to her bed, falling down to the floor, laughing their asses off until he comes like a good boy and not caring for her like a bad man but she is okay with it like a good girl
He's so tired he has to lay down..poor fella.
HAPPY END
(thats also the name of an awesome japanese 60/70s band by the way!)
