ahh.. I’ll love to write this for you!
ok, so here is how I’ll give you your first anal sex:
To begin with, first we’ll need to make sure that nothing comes out from there when we are having the fun. Well, not that I won’t like it if something do come out, but guess you’ll agree that it’s better to have a moderately clean anal sex. So let’s make the initial cleaning part fun!
I’m sure you’ll agree watching and being watched in the toilet is fun. Those are some of the most personal moments, exposing which to your partner opens up a whole new world of erotism. I’ll watch you in the toilet. To make it a little more explicit, you’ll get up on the rims of the toilet bowl (sort of like this lady: http://porn-inside.biz/dtr/thumbs/ebe8a9.jpg - sorry about this reference from a porn site, but I really like this posture :). That will give me a clearer view of what’s going on!
But I promise, I won’t interfere. And all along that time I’ll be standing before you, and you may have my dick to play with while you poop. :p
So once you have done all you can, we’ll flush the toilet. Then just to be double sure that there isn’t anything big left inside, I’ll do some slow and gentle fingering inside your ass. We’ll try something sensual while doing that: when you try to push out, I’ll move my finger inward counteracting your effort, and when you try to pull in my finger I’ll move outward, again counteracting your effort. This will continue slowly until you feel bored/tired. But I’m pretty sure you’ll love it too much to want to stop it! Believe me, this will be more pleasing than anything else you have ever experienced!
Once done, I’ll definitely wash my hand, but you hold on… don’t use the toilet paper yet! Now you get down in doggy style posture on the bathroom floor, and I’ll use my tongue to gently clean up your anus. Slowly and gently I’ll roll my tongue on the rims of your anus, and then penetrate little inside to lick up all the tasty juice you have let flow from there!
So now that we are ready to get started, we’ll do a little foreplay. For playing with the anus, 69 will be a good position. You may fiddle with my penis, while I’ll finger your anus and pussy with both my hands. We can once again go the counteracting thing if you please.
Then we’ll have the condom in place and your anus all greased up (with my saliva mixed with your anal juice) we’ll start the main play in doggy style. Slowly I’ll get my penis inside. Once I’m completely in, I’ll stay there.. as long as you want me to. You’ll push and pull me inside you, and I’ll watch you doing that. Once it’s long enough, I’ll slowly start pulling out, stopping often as I do. Once totally out, I’ll lick your anus and take a look inside there, and then again start pushing in my penis slowly. This we’ll continue for long, and we’ll steadily increase the speed. All throughout I’ll fiddle your clit with my fingers. We’ll do this until you have a real good orgasm!
I can stay erect in multiple orgasms. So it won’t end unless you have felt the ecstasy!
After all is done, we’ll throw away the condom. Then we’ll go to bed with you holding my dick, and me with my finder stuck inside your anus. I’ll gently undulate my finger in there, like a lullaby, as you go to sleep!
By the way, all along you can do similar things with me. I mean you can finger my anus, lick it, etc if you want to. I’ll love it. Although you needn’t if you don’t want to.
So, how do you like my story?
