This story is based on a story I was told by a friend:

 When we were first married (before we had kids) my husband and I would play a game we called "the sexy beast." When we were alone together, one of us would randomly strip naked and pretend to be a "beast." We would chase the other down, rip off their clothes, and "force" them to have sex. It was all in good fun of course because, back then, we had all the time and desire for it. The fun of it was it could happen at any random time. First thing in the morning, right before going to bed at night, during meals, anytime. 

One time, it was my turn to be the beast. I was in my pajamas making an egg for breakfast and my husband came in wearing a suit and tie for work. Suddenly, I started growling. Knowing what was coming, my husband tried to run, but I stripped out of my pajamas and took off after him. Before he knew it, I cornered him in the bathroom, shoved him into the tub and poured the gooey egg mixture I was still holding all over him. His nice suit was saturated in egg but he was laughing because he knew, this was the game. Next, I did what we called "marking territory." In other words, I crouched over him and peed on him. We did not do that every time, but it was a kinky thing we liked to do now and then (more times than I can remember, I have awoken in the middle of the night to him standing over me naked, soaking my pajamas and the sheets in pee). His suit was completely ruined by egg and pee so I tore it off and turned the shower on and we made passionate love as the mess was washed away. He was a bit late to work that day, but we loved every second!

Another time, he was the "beast" when we were out in the middle of nowhere hiking and we had sex in the middle of a mud puddle. We both finished the hike naked and muddy that day!

Still another time, it was out anniversary and we got all dressed up in formal clothes and went out to eat. When we got home, it was raining, but it was his turn to be the beast and we ended up playing in the rain and mud of our yard (we have no close neighbors who could see us) until our formal clothes were ruined but we were ecstatic.

Just the other day, it was his turn again to be the beast. I got home from work and saw his car was there, but when I went inside, there was no sign of him. I was instantly on my guard as I went through the house. I was wearing a red and white dress, dark gray-ish stockings, and tan flats. I made it to the bathroom and started to let my guard down. Maybe he went for a walk or was working in the basement or something. I started to undo my clothes to use the toilet when I heard it...a swish from the shower curtain. I squealed when the curtain was pulled back and there stood my husband, in all his naked glory, his penis pointing straight out like a spear. 

In an instant, he had pulled me into the shower and stood over me as I lay on my back. I looked up and saw that he was aimed straight at me. Suddenly, a wash of warm pee washed over me, soaking my hair and face as well as my dress. I had to go too, so I just peed myself and felt it flow down my legs over my stockings and into my shoes. Both of our flows lasted until I was drenched from head to toe in pee.  Then, my husband was on me, pushing up my dress and ripping my panties off. His other hand, meanwhile, pulled down the front of my dress and my bra and kneaded at my already stiff nipples, eliciting a moan of pleasure from me. He was astride me next and I felt the hot, hard, throbbing spear of his penetrate me. I cried out in a delicious moment of pain and pleasure mixed. My outstretched hand blindly found the spigot and I turned on the shower. We were soon awash in water as we coupled passionately, rocking in rhythm to our love. His hands and mouth were all over me, awakening me. But nothing could distract me from the throbbing of himself deep inside me. After what seemed too short a time, we both climaxed simultaneously as he shot a hot flow of lava into my deepest part. We screamed in passion and pleasure as he pulled out of me. I licked his penis clean, earning a few more squirts of his seed over my upturned face. But we weren't done yet, oh no. As we were drenched by the water, I made him come again and again, with my mouth, with my hands, with my tattered stocking feet, between my breasts. This was the most fun part of it for me. Because, even though he was the powerful beast, I was the one with the true power, making him lose himself to me, give me the most intimate part of himself, over and over again. 

When we finally exhausted ourselves, we lay in the bottom of the shower, the water still soaking us, kissing and touching softly. My dress had, surprisingly, survived mostly intact although soaked, with what holes there were easily sew-able. My stockings, though, were torn to shreds and covered in pee and cum stains. I peeled them off and threw them out. My shoes were, of course, waterlogged, but otherwise unharmed, so I slid them on to my bare feet. We finished washing off and then, with him naked, and me wearing nothing but my shoes, we climbed out of the shower and went about our day. You can be sure that, once we had recovered a little, we would make love again today. And, I was already thinking of how to get him, now that it was my turn to be the beast.
