Nearly always when I'm in the shower, thinking of a late teen girl or early twenties woman I've seen at a dance class when I go to the gym. Beautiful, young, slim, imagining her there in the shower with me, back to me, her hands pressing the tiles, my cock rock hard and raging with desire, pressed against her back, aching to go into her little butt. Cover my cock in shower gel and imagine I'm lubricating it for her, then reach down and grab her little waist and lift her on to me as she holds on to the shower head and I press myself against her tightness and she gasps, then she feels the lubricant and relaxes her anal muscles and she slides down on to me. Now I moan as I'm absorbed into the silky heat of her bowels and I'm on the verge of coming almost immediately. Depending on how much time I have I'll let this go on for some minutes as the orgasm is better the longer I hold back, then I'll finally have to let go, my legs shaking as I imagine impaling her and pumping her and holding her gorgeous little titties and hard nipples as I let loose a gusher of cum into her pooper, biting the back of her neck or her ear as I shiver into her.
Sometimes my GF won't be in the mood for sex in the mornings, but then she'll come in the shower while I'm there and already hard, and she'll soap me from behind and whisper "Oh baby, look at you. What are you thinking about? Are you thinking naughty thoughts?"
"Yeah," I gasp.
"About some gorgeous young hunny?"
"Yeah. I know it's wrong..."
"It's ok," she says, "it's only a fantasy." And she keeps stroking me and I'm very hard, and she says, "You're imagining her little butt aren't you - I know what you like."
"Oh yeah..."
And she jerks me, and a soapy finger plays with my butt and I moan and I know it's going to be a good orgasm and she says "Imagine how good it would feel inside her, yeah that's what you want."
And she keeps stroking and fingering. "Fucking pretty girls in the butt, it's all you want isn't it?"
"Oh yeah!"
"Go on, honey, come for me, fill her guts with your cum..."
And I'll shake and cry out and spray the walls.
After she'll squeeze me to get the last of the cum on to her fingers and wash it away, and we'll kiss and I'll tell her how much I love her, especially for understanding my wrong desires, and she'll say it's ok no one will ever know, it's our secret.
Ahhhhhhh. Until tomorrow morning and all over again.
