One of my favorite tricks is to fill a condom with water... not to bursting, but just so the condom is full length and maybe an inch and a half across, so the rubber is just starting to stretch... then tie it off like a water balloon.
Lie on your back spread eagle, add a little lube if the condom is not pre-lubed or if you like it even more slippery... then hold the bulk of your water cock in the one hand and aim the little reservoir tip at yer ass.
Make sure yer nails are trimmed other wise you may burst it before you get it in there... With your free hand, start to push through the one side of the condom and up to the tip and push it into yer anus, try and slide your finger out just a half inch or less to push a little more in there... once you get say an inch or two of squished condom material in there, GENTLY squeeze with the support hand and the material that's inside will inflate and drag some of the condom inside from out.
Once you have about the condom about half in and half out, just squeeze with your support hand and you will super-inflate with all the water, the portion of the condom inside you and then let go and make sure your ass is relaxed and all the water comes rushing out to fill the outer portion of the condom... once you're relaxed you can squeeze and relax pretty fast and water fuck yourself. It's pretty cool, and fun... Experiment with different water temps to find out what you like. And remember to lay a towel or two down under ya!
I first discovered this trick when I used it on my first lover. We were having a water balloon fight and I ran out of balloons so I ran to my room and got a frenchsafe! Loaded it too much and when I let out some of the water so it'd have some snap, I just looked at the super soft phallus in my hand and got super horny. I yelled at her to get in here quick, tossed her on the bed, ate her out, and then slipped it in there. She was startled at first cause it was so cold, but once I started forcing the water in and out, she approved. Sooo.... Good trick for anal or vaginal....

Every girl I've tried it with has loved it, and while I've never had the opportunity to do it on a guy, I've done it to myself and loved every second.
One trick time, I pushed the whole condom inside so it rested nicely in my body and jerked my tube snake real good. Once I came (buckets I might add) I just went to the bathroom and shat it out! Very nice time! Have fun.
