The Right Impression

"it's not that..." I replied. I shivered at Sophie's touch. I was still very sensitive.

"You want more of me then?" Sophie asked, brushing her breasts against my groin. But she knew what I was thinking of. "You're an incredible person, Darren. It takes a lot to resist like you did. You didn't touch me."

"So do I pass the test?" I asked. My voice was quivering. Sophie really had me close to the edge.

Sophie sighed. "I was hoping you wouldn't. Now I'm dripping wet." She moved closer to me. "Are you sure you don't want to indulge before you commit? I won't tell."

"I..." I felt something wet against my back and shot upright, nearly knocking my head against Sophie's. "What was that?"

"What was...ew!" Sophie recoiled, also feeling something slimy. "Oh yuck, we slipped into mud."

Ignoring the fact that we were both stark naked, we got up and wiped the mud off skin. Something was dangling in the back of my mind. The mud patch felt out of place. The entire pit had been dry the whole time, and it wasn't raining. Something happened while Sophie was giving me a blowjob. As I regained blood flow to my brain and control of my thought processes, I became aware of something else.

"Do you hear something?"

Sophie went quiet. "Water? But where?"

It was a quiet gurgle. I struggled to make sense of the puzzle in front of me, but all I had to work with was the mud patch. That definitely weren't there before.

"Whoa!" Sophie yelled out, windmilling her arms. The soil she was standing out suddenly broke away and she nearly fell into the mud. I pulled her back by the waist and we both stepped back in time to see the glisten of the now-undulating mud where we were standing.

"What's going on?" I asked.

"Darren," Sophie said, holding me around the torso. "Didn't you say that this pit was made by an underground current?"

"Yeah, but..." Sophie and I looked at each other. We didn't need to say the word. Whether you call it a sinkhole or a quicksand, we were trapped in it.

"What are going to do?" Sophie asked.

We were calm. The excitement from our strip game and make-out was replaced by a controlled, thoughtful assessment. The patch of mud was expanding towards the middle of the pit, so we shuffled over to the far side, where the dirt was piled up the most where we had fallen in. We thought about putting our clothes back on, but they were scattered over the unstable mud, along with the now half-buried backpack.

"How long has it been?" I asked. "Tara must be close."

We tried calling out for Tara, but there was no reply. We weren't even sure if our voices could be heard outside the pit. Naked, we hugged each other. Feeling Tara's warm body against mine, and her soft breasts squish against my torso, sent another wave through me. My penis brushed against her pubic hair, slightly damp from her arousal. Thoughts filled my mind again. The danger was not too urgent, not enough for the adrenaline to kick in, and Sophie's soothing embrace was making me feel more excited. I realised then that it was actually my own arms keeping Sophie pinned against me. She said nothing.

We looked down at the disintegrating soil. The edge of the dirt pile was beginning to slide into the liquefying mud, turning it into a thick sludge. We could feel the dirt moving beneath our feet, moving towards the muddy trap. Bubbles began to appear in the deeper areas.

"How deep do you think it is?" Sophie asked.

"It can't be that deep. It won't suck you under. Quicksand doesn't work that way."

There was something about what I said that sent a jolt through me. Maybe it was the quicksand part. Or the sucking. This wouldn't sound abnormal in a classroom, but Sophie's naked body rubbing against mine added another connotation that I didn't think of at the time. We could both feel the soil become damp under our feet, and we settled into it an inch. We didn't make a sound. We were scared, but at the same time, unspoken, we were still very turned on. I could feel it. She could definitely feel it. I would never forget her soft breasts and hard nipples squashed against my chest. Since we were the same height, our cheeks were touching. As she pressed up closer against me, I felt the base of my penis touch her moist slit. Sophie's body shook; the intimate contact sending sensations through her body.

Our descent into the quicksand was not as I had imagined. Instead of the mud cracking and sending us straight down, we were lowered into the sand, as if we were standing on a shelf that was being pulled down. The mud opened up around her legs and then swallowed them, forming a thick, sucking seal around our skin. The mud was surprisingly smooth and warm. Our entrapment played out in slow motion. We made no attempt to escape, only holding as still as we could to stop the mud from simply snatching us in one gulp. The opportunity to get our legs free passed when the quicksand took hold of our knees. There was a gurgle, and we suddenly slipped deeper. Sophie noticed that I was going down faster, and my head was approaching her chest. We were so close that my nose was nuzzled between her soft breasts.

"Getting comfortable?" she asked me.

"Mmm."

"I'm so turned on right now, Darren."

"Mmm."

"Darren! Don't spoil the mood."

"Well, we're trapped in a sinkhole, and I'm trapped between your boobs."

"Well, you do owe me a blowj...wait, are you holding me up?"

"I might be."

"Darren! No, please!" Sophie protested. "You don't have to do that. Stop that right now!"

Sophie wrapped her arms around my shoulders and tried to pull herself down to my level, but tremendously miscalculated her move. The mud bubbled and she leaned forward. Next thing I knew, she slid right on top of my erect penis. She had been dripping wet, and there was no resistance as she took my entire length.

"FUCK!" we both shouted in unison. She tried to pull herself off immediately, but the mud was now around our thighs and the weight of it around her legs were too much to fight against. She tried squirming free, but each movement wracked her body with pulses of pure ecstasy, and the same was happening to me.

"Hold...ugh...still," I gasped. I was caught between lots of things: Sophie riding my cock, the fact that I was literally fucking my future sister-in-law, and the quicksand liquefying beneath us. "Making...it...worse."

"Can't move," she groaned. "OH GOD."

Holding still just didn't help. Sophie was already over the edge and was humping me. Even the smallest shifts were enough to rip through her control. Her pussy lips glided up and down my shaft, each time hammering me down into the mud just a bit more. The mud seemed to heat up with our intensity. As the mud surrounded our buttocks and made movement harder, our pace change. Our rhythm was staggered, partially fighting against the mud and resisting a deeper urge, partially giving into it. Neither extremity helped us deal with our lust or our peril.

Sophie suddenly doubled over and slumped over me; her weight pushing me down deeper. Our bodies were sticky with sweat, and I could hear a tinge of elation in her gasping.

"Are you alright?" I asked.

"Yeah," she said with a coy smile. "Just hit my orgasm."

The quicksand gurgled again, having patiently witnessed us. It was around our waists now, and there was no chance of getting out of this by ourselves. "Shit," Sophie muttered. "I didn't mean to- OH GOD!"

I was still inside her, and I hadn't reached my peak yet. I wasn't trying to either. But now with the quicksand pushing us closer together and Sophie catching up with my descent, I was thrusting deeper into her. "Damn it, Darren," she gasped. "Ugh, can't...stop..."

"I just hope Tara doesn't see this," I said, trying to hold in the throbbing pleasure below.

There's always this thing about speaking of the devil. Tara had not heard us in the sinkhole, nor did she have any inkling as to what was happening down here. When she appeared above the hole, she was with another man who happened to have a rope. His friend had run back to get help.

"Yoohoo!" she yelled from above. She couldn't see much inside the hole. She definitely couldn't see us naked and still involuntarily going at it. "Are you still there?"

"We're down here!" Sophie yelled back. She stifled a moan. "The hole's turned to mud. It's like quicksand."

"Oh my god!" Tara screamed. "Don't panic, we'll get you out. Come on, Paul, hurry!"

"Relax hun, they're not going anywhere," Paul replied in a deep voice. He unravelled his rope, tied it to a nearby root and began to lower it.

"Wow," Sophie whispered. "I'm going to have to do him a favour for this." She giggled too. "It's going to be hard to keep this quiet between the two of us."

"How deep are y'all?" Paul shouted.

"We're nearly up to our chests. The mud's pretty soft though." Sophie replied. She noticed that I had become stiff and quiet. "Something wrong, Darren?"

I groaned. "Trying to...hold it in..."

"Hold what...OH!" she felt my penis twitch inside her. "Oh god, please don't come inside me."

"Trying not to!"

"Rope's coming down! Watch for it!" Paul's voice echoed.

"Okay!" Sophie turned back to me. "Think of something else. Drowning puppies."

"Not helping," I mumbled. "Your puppies are in my face. And you're REALLY grinding into me."

"I can't help it!" She twisted her hips to loosen the mud. "If this goes any longer, I might orgasm again."

"Don't say it!" I shouted.

"Is everything alright down there, honey?" Tara called.

"Y-yeah! Yeah, fine!" I shouted back. I've never felt so torn and embarrassed before. I was still inside her sister trying not to ejaculate.

"Maybe you should think of my less hot sister," Sophie suggested.

"Not helping!" I could see the rope just above Sophie's head. "There! Grab it!"

My arms ached as I pushed Sophie up. It really did nothing against the weight of the mud, but it was a symbolic effort to part with Sophie. I gave her up willingly, not corrupted by the lust for her. Anything that could stifle some of my guilt. Tara's smiling face was like the sun above me. We were in the darkness. This wasn't meant to be real. I tried to remember Tara as Sophie slipped free, and I hit my peak. I closed my eyes, blinded by an imaginary light. My body jolted and I released everything I kept contained. My juices became one with the mud and my sore loins relaxed. Sophie was already a few feet above me, slowly scaling the wall. Her feet kicked a few grains of dirt onto me.

"Nearly there," Paul assured her. "Is your friend getting deeper?"

"He's up to his shoulders," Sophie said as she was pulled up. She was so covered in mud that Tara didn't notice that her sister was naked. Paul, however, glanced through the corner of his eye. Sophie smiled back.

It took over two hours for me to be pulled out. The rope ended up being short and they didn't risk falling into the collapsing hole. The rescue teams eventually pulled me free. By the time I was out, Tara was so happy that it never occurred to her to ask why I was naked, and she was none the wiser.

While Sophie and I were covered in blankets under observation, we exchanged a guilty look at each other. I wasn't sure what to say after what had happened. Sophie looked at me with sympathy.

"Don't think about it too much," she said gently. "I don't feel bad about it. It happened. Don't let it ruin a good marriage. It was my fault anyway."

I sighed. "I don't know what to tell Tara."

"Just tell her we had a deep and meaningful," she replied.

"Very deep."

"In more ways than one." She smirked. "Seriously Darren, don't tear yourself up over it. Now you can screw Tara and never have to fantasise about the sexy sister-in-law ever again."

"Thanks...I guess?"

Sophie came over and gave me a hug. "I mean it, Darren. You're a good guy. I know what you were thinking in the back of your mind. You still wanted to protect me. I know you'll be a good partner for Tara. She needs someone like that." She kissed me over the lips. "And someone who is very gifted in bed too."

"Sophie!" I pushed her back, but it came out more playful than angry. "That's now how I wanted to make an impression on you!"

"At least it's the right one," she replied.
