Fooling around.

I hold Jane's hand as we walk into my house and up to my bedroom, letting her go in first so I can see how great her ass is.
"I'm home!" I shout as I go upstairs.
As soon as me and Jane get to my bedroom she hops onto my double bed, bouncing on it playfully before lying back on the pillows, smiling at me.
I walk over to her and lie down next to her. I put my arm round her waist and stroke her smooth stomach. My head leans into hers and she sighs. I turn to her and place light kisses on her cheek, which slowly turn into little licks, at which point she giggles, and turns to lick me too. We lick each others faces for a minute whilst continuously laughing until we both begin to kiss each other passionately, all sense of humor gone. She blushes slightly, and she still seems so perfectly innocent.
To stop people from coming in I get up and lock my door. To cover up Jane's cute little moans as I kiss her I turn on the TV. Our makeout session continues until I get bored. So I flip her round surprisingly, and her moans get muffled as her face is shoved into the pillow. For a joke she sticks up her cute ass and gives it a wiggle, which, to her surprise, I proceed to bury my face in,making her laugh.
She is still overdressed, so I take down her tights and panties, but leave her skirt on. I push her skirt up a bit and spread her ass cheeks, noticing how tight Jane's cute little anus still is, almost as though she were still an anal virgin.
Starting at her shaved pussy, I run my tongue all along up through her crack, before shoving it in her pink asshole. She squirms and shows signs of resistance until I slap her ass, at which points she relaxes her gives me full access. Not being able to take it anymore, I drop my pants and reveal my cock, which she can't see yet. I begin to rub her clit with my hand till she almost screams. Thankful for the soundproofing pillow I ram my dick straight up her anus. Her ass clenches from the sudden intrusion and she comes to an insane orgasm. As I come close to cumming myself, I bend over her and grab her tits aggressively. This had gone further than either of us expected.
"Ah yes Jane! I love buttfucking you!" I whisper as my seed completely fills her up, her ass clenching hard around my cock as she too cums. I then pull down her skirt, but keep my dick buried inside her as I lie down on my back with her on top of me, panting like a dog.
Then there is a knock on the door.
