I resurfaced from the cool pond, bathing myself. I owned a small cottage all alone in the woods, and next to it was a private pond. I would bathe myself in it fully naked whenever I liked. However, I was not alone. I resurfaced onto the grass by the bank of the pond and started sunbathing.
I began to think about this one guy I liked, C/N. He seemed so perfect. I couldn't get my mind off of him.
Suddenly, a tentacle slowly rose out of the pond, tall and thick. It rubbed my back and I smiled at it. "Hello there!" A tentacle monster lived in the lake, never showing its face, but it had many limbs, all being tentacles. It was kind unless I asked for it to be rough. It appeared whenever I was feeling dirty, and helped my needs.
"Would you like to help me out?" I asked, pretending to be innocent. It gently wrapped around your legs. This time, I wanted it to be rough. It could sense this and spread my legs apart quickly. It restrained my hands tightly above my head, making me feel more exposed than before. Tentacles brushed across the grass and slithered underneath me, supporting me in the air.
Two tentacles climbed onto my chest and wrapped and twisted around my boobs, arousing them by sucking them with suction cup tentacles. Another tentacle rubbed my entrance, making me moan in response. It continued to tease me. "Please," I begged, "I can't wait so long.. I need it now." The tentacle understood this and the one rubbing my pussy repositioned to directly face it, and penetrated me suddenly. I gasped and screamed in surprise and pleasure.
It went deeper than it usually goes, causing me to let out another gasp. I uncontrollably moaned and gasped, so to shut me up, another thick tentacle covered my mouth. The tentacle inside me thrusted in and out of you violently, while you let out muffled moans and screams. The tentacle suddenly stopped, and I was jerked upright to begin bouncing on it. This made the tentacle to manage to slip deeper.
The tentacle covering my mouth uncovered it in the middle of my bouncing, to hear me let out another gasp in pleasure. Suddenly, the tentacle slipped down my throat, mouth-fucking me. One tentacle reached behind me and slapped my ass to make its appearance. My eyes widened in shock for a moment before the tentacle traveled into my ass. I felt do good being fucked in every hole at once. It felt so naughty but nobody would know, right?
I was now bouncing up and down on both the tentacle in my ass and the one in my pussy. I finally orgasmed, cumming onto the tentacle inside my pussy. A milky substance dripped down the tentacle and my legs. It came inside me as well, slipping out and mixing with my own cum. More tentacles emerged from the water, holding me in place. This informed me that this was only the beginning.
A tentacle way thicker and bigger than the rest emerged, and the tentacles inside me all retreated and helped restrain me. The thick tentacle wandered towards me, and pushed its way into my pussy, shattering me with pleasure. It began to fuck me fast and thoroughly, making me cum right away. Cum splashed out of my entrance with every thrust the tentacle made.
This went on for hours, longer than usual. I soon grew tired and informed the tentacles, making them retreat. They slipped inside the water and I lay there, with every move I make end up hurting. That was amazing. The summer breeze brushed against your body, tickling you slightly. You bathed again before heading inside your cottage.
