“Take your bathing suit off.” Steven growled, impatient.
I stripped down and asked how he wanted to do this. I really didn’t want sand in my ass.
“Get on your hands and knees. I’m gonna fuck you like a dog.”
I did as he said and got down. He licked a finger and touched my asshole. Involuntarily I clenched briefly before remembering and relaxing. My hole was still slightly loose from the assault the night before; Steven’s finger slid in without difficulty.
“Still a little loose huh? That’ll make it easier at least.”
Steven got down on his knees behind me and for the second time in 24 hours Steven began to eat out my ass. His tongue was so wet as it slid in and out of my whole. The pleasure was so good but I wanted more. I wanted his cock. Steven wet my asshole thoroughly and loosened me up a great deal more by the time his tongue finally left my hole.
Like the night before Steven moved around to my face and pushed his cock towards my mouth; I didn’t need instructions. For the second time that day I took his dick into my mouth. I took as much of his cock as I could, wetting it down with my saliva as I sucked on it and ran my tongue along it. I could taste some residual salt from his brief dip in the ocean when we first got to the beach.
When his cock was wet enough he pulled it from my mouth and moved back around behind me. He rubbed his cock up and down a couple times, spreading my spit around. He quickly relubed my ass up with his tongue and then positioned himself.
“Ready?”
“Yes please.” You could hear the need in my voice.
Steven placed the head of his cock against my hole and I moaned in anticipation of the pleasure that I knew was coming my way. Steven started to push, sliding his cock into me. It went easier and less painfully than it had the night before. I guess you get used to being fucked I thought. Steven kept pushing steadily, quickly sinking the full length of his cock into me.
“Mmmm…” I moaned.
Steven kept his cock buried in me for a moment to let me get readjusted to having him in the depths of my ass. Slowly I felt him pull out and then push back into me. Steven continued to fuck me, slowly at first but speeding up gradually. With each thrust of his hips his body would slap against mine and his balls smack against my balls. The sounds of us fucking, the moans, groans, and slaps, turned me on almost as much of the very fact that my brother was inside of me. I had yet to touch my cock and it was rock hard and swinging between my legs. On exceptional hard thrusts my cock would swing up and hit me in the stomach leaving a small wet spot of precum.
“How are you still so tight?” Steven moaned, “Sarah always loosens up a bit when I fuck her. Your ass feels just as tight as it did last night.”
Steven knew that this couldn’t be a marathon session. We didn’t have hours to fuck like we had the night before, our parents were down the beach and they were probably wondering where we were by now. I looked back and saw a look of pleasure on Steven’s face as he pounded my ass. He grinned at me and slapped my ass
With one hand I grabbed my bathing suit and wiped my hand on it. While Steven continued sawing his dick into me I reached beneath my legs and grabbed my own cock. I started to jerk off, determined that I was going to cum too. With Steven fucking me like he was, hitting my prostate with each thrust, and how turned on I was, it wasn’t going to take me long to reach orgasm.
“I’m getting kinda close,” Steven gasped.
“Just hold on a bit longer,” I begged, jerking my cock harder and faster.
“I’ll try.”
Steven slowed down a little bit, trying to hold off his orgasm so that I could cum. I felt some his sweat drip onto my ass and that turned me on a little more. I continued jerking at a feverish pace. I wanted to cum so fucking bad. I started to feel that familiar feeling deep inside me and knew that I was getting close.
“I’m getting there.”
“Gotcha.”
Steven started pounding into me again, working to shoot his cum into me. Both of our breathing became erratic as together we approached orgasm. Beneath me my hand was practically a blur as I jacked off. Behind me Steven was humping me as fast as he could in his need to fill me.
“Fuck yes!” I moaned as my orgasm hit me.
My ass clenched around Steven’s cock, increasing the friction, as I started to cum into the sand beneath me. Five strings of cum exited my cock and landed in the sand. I almost collapsed from a combination of the pleasure of my orgasm and Steven’s pounding. I rode off my orgasm, out of breath as I felt his cock start to swell even more and pulse inside my hole.
“Here it comes,” Steven said hoarsely.
He roughly thrust into me once more, holding his cock balls deep inside me to shoot his cum as far into me as he could. He gasped with each pulse of his cock as he filled me up. He placed his hand on my back for support as he too coasted off of his orgasm.
He pulled his cock out of my ass leaving me feeling slightly empty and very loose.
“That never gets old,” Steven said with a grin on his face, looking at my gaping ass.
He stuck a finger into my ass and wiggled it around a little.
“What are you doing?”
“I dunno. Just seemed interesting.”
Steven pulled his finger out of my ass and showed it to me. His finger was covered in his cum from my ass.
“You want some?” he asked me.
The idea of tasting cum that had been in my ass both disgusted me and turned me on at the same time. I nodded and opened my mouth. I sucked on Steven’s cum covered finger, cleaning it off. I love the taste of his sweet cum but this time it had a slight nutty flavor to it. I wasn’t sure how I felt about that.
“Good?” Steven asked, clearly quite curious.
“Why don’t you have some?” I joked, shaking my ass at him.
“No thanks. Not much of a cum slut.” He said and stood up.
I clenched my ass and followed suit. As much as I clenched my ass it wasn’t enough and Steven’s cum started leaking out and down my legs.
“Looks like you need a little dip.”
“Looks that way.”
We got our bathing suits and made our way out of our little hideout and into the sun. We walked down towards the water, cum continuing to drip down my legs. Steven reached the water first and ran, diving in and surfacing several feet further out. I decided it would probably be safest if I just walked in. We floated around for a while letting the cum leak out of my ass and wash away in the water. We didn’t talk much, just floated.
When we finally got back to where our parents were they were both ready to go and were quite interested in why we had been gone so long. We said that we’d walked really far down the beach and then got in the water and let the current carry as back to where it was time to get out. That answer seemed to satisfy them and they didn’t say any more about it.
Steven felt like a burger for dinner so we decided upon Steak & Shake for dinner since my mom loved their milkshakes and melts. Dinner was much better than it had been the previous night and the conversation was lively. We all reveled in the color we had gained.
