Nothing

She takes hold of your shirt collar and brings you up to her face level. Your mouth is still open but you soon find your mouth covered with hers as she kisses you. Her tongue meets yours, she is tasting her own cum.

Then, she smiled and said "You know you're a very naughty boy? I was hoping to fuck that nice tight arse of yours. But you surprised me with that nice blow job."

You smiled and said "I aim to please. When I saw your cock I couldn't resist; it was so beautiful."

"So did it taste as good as it looks?" You start to realize she has a sense of humour.

You hug her, and as you press your bodies together, you reach around her and take hold of her bum. A cheek in each hand and moved them around as you went back to kissing her on the lips. Then you slipped a finger in her anus, then a second one, and she did the same to you. You both started finger fucking each other's arses.

She broke the kiss, put her lips close to your ear and whispered, "Fuck me."

You got behind her, lifted her skirt and brought your cock close to her bum. She reached under herself and guided you to her bumhole. With only a little push to get past the sphincter you found yourself in her anus. As you started to fuck her, you felt her passage become tighter around your cock. Not too tight, but tight enough that you could feel every inch as you moved in and out of her arse.

At first she was bent over and you held on to her hips. But then, she stands up and you reached up and cupped her breasts. You kissed her cheek and neck as you kept fucking her arse. You got her nipples between your fingers and played with them. It was all too much and you started cumming in her asshole.
