*****
I tried to climb off my sister as soon as she'd orgasmed, but she held me there.
"Stay in me. It's lovely, having your cock in me."
So I did, and after a few minutes my now-soft cock just slipped out of its own accord, wetly. I was aware of warm secretions all around my groin, and because of the drink I'd downed that day I was also aware I needed to piss.
"JJ, I need to take a leak. Back in a sec."
"Oh wait! Um, can I hold it while you go? I've always wanted to do that."
"Er, OK. If you want."
Standing over the toilet and holding my cock from beside me, she said: "How do you aim it?"
"Um, maybe this ain't such a good idea. I don't want to have to clean the bathroom."
"Get in the shower then."
We did. There was not much room and we stood facing each other so she pointed my dick at the shower wall. I let go a dribble and a spurt, which seemed to delight her. I closed my eyes to relax and let go, which seemed to work. When I opened my eyes I looked down to see my sister was aiming my piss stream at her tits.
"Oh wow that's warmer than I thought. Tickles a bit."
She looked at me grinning like the cat with the cream. I just pissed and let her play the stream wherever she wanted. Then she hit on the idea of parting her pussy so she could have me piss on her clit.
"Mmmm, that's hot! Sexy hot and warm hot. Um, Mikey?"
"Yeah?"
"Can I pee on you too?"
"Er, sure I guess."
I no sooner finished than my cock began to rise. I had often fantasised about watching a girl pee and now
my own sister
was going to do it for me.
"Mikey, I can't aim upwards like you. Kneel."
I did. We were so cramped in that shower cubicle that my lower arms were around her knees. She pushed her pussy forwards a bit with her hands on my shoulder to steady herself.
"Ready?"
"Yeah."
A few seconds passed, and then she sighed as her muscles relaxed and a thin stream of pee left that gorgeous bald pussy and splashed down my chest and around my cock.
