I have a girlfriend who likes holding pee and having hot piss sex. Our favorite thing is to get up in the morning and have full bladder sex. Sometimes, however, I suggest we wake up, play for awhile, then get up, get dressed, and go to McDonalds. Since it is only 2 blocks away, we are safe in case either one of us has to piss. As we walk we laugh as our morning bladders are bouncing up and down in our pants. I have a hard time keeping my dick soft as the combination of a full bladder, a full load of cum, and my dick rubbing up and down in my jocks makes it hard. Mary can hold alot of pee, but sometimes her bladder spasms and she has to stop and cross her legs. I am sure the men looking out their windows at this time get a free show. We always make it to McDonald's without pissing our pants. We order coffees. Mary likes iced coffee. We sit in a booth for atleast an hour holding our morning piss. It is so intense because we both know how each other feels, and I want to put my hand on Mary's pussy and rub it till she cums. She puts her hand on my leg up high, and that makes my pisser so hard, I want to burst. Mary looks at my piss hard-on and laughs and squeezes her thighs together tight. After an hour, we depart. As Mary gets up, she bends over as her bladder is so full it feels like exploding. Then we are off on our controlled walk back to my house. Our bladders are now at 98% and we wonder who is going to show piss on their pants on the way home. I want to put my hand in my pocket and rub my half-hard piss cock, and I know Mary really needs to rub her pussy to hold back the flood.
We barely get home and both are doing the PP dance. We strip and dance in front of a mirror. There is something so erotic about doing the PP dance naked while looking at the other person. I go behind Mary and rub her nipples and her pussy as I rub my now very hard cock against her ass. I come around her with my head and jam my tongue in her mouth and give her, what we call, a big piss kiss. She returns with her tongue as we piss kiss together with our bursting bladders. There is also something hot about kissing like this when you are horny and full of piss at the same time. We do this till one of us can't hold it anymore and something starts leaking or in my case squirting straight up. Then at this point we jump into bed and we alternately jerk each other and lick each other's bursting cocks and pussies to help hold in all the piss. Mary loves her pussy licked when she has to pee very bad. I then get on top of Mary and as I enter her bursting pussy, I kiss her hard. We rock and roll in bed till we both cum each atleast once. That is the rule. Then we run to the toilet and while Mary sits down, I kneel and kiss her, and piss on her hairy bush till we are empty. What a way to start the day. I think for a girl to like this, she has to love you, you have to make her feel hot and sexy, and pleasure her sexually during the event. It always works for me.
