My cheeks were flushed, and it felt as though I was enduring a rigorous workout. Max was panting down my neck, making me increasingly uncomfortable. I attempted to wriggle my neck away from his heavy breaths, but the constraints of the costume made it impossible.

Desperate to escape the situation, I endured the assault of his hard cock against my pussy and forced myself to take the last three steps up the stairs while still on tiptoes. During those steps, his cock slipped out and re-entered me repeatedly.

When we reached the second floor, the nearest room available was his, merely five steps away. I noticed he was standing a bit more upright than when we were on the stairs, and he nudged me a bit harder below. It seemed like he wasn’t trying as hard to pull his cock away from my pussy anymore. But perhaps I was being overly sensitive, so I ignored it.

I said to him, "Max, let's go to your room and change, okay?" He didn’t reply. We took small, cautious steps towards his room. As we walked the first two steps, his cock continued sliding in and out of me. It felt really weird now.

We could walk much easier on level ground, but still, his cock stroked into my pussy. It took me a second to realize that Max was subconsciously pumping his hips as we walked in the costume. Worse, he was trying to push himself deeper into my wet slit with each step we took.

I was totally concentrating on making my way to his room and wasn’t aware that he was already stroking about two inches of his manhood into me from behind. But we were almost at his room. I only had to put up with him for the last few steps. Then I’m going to strip myself from this costume and give that little weasel a piece of my mind.

I kept my silence and pulled him with me as I took the lead. All he did was take the chance to push his hips against me and drive more of his hard cock inside me. We finally reached his door, and just then, my knees buckled under the constant strain of my awkward tiptoed posture.

My legs gave way, and I impaled my poor pussy on his cock, unexpectedly driving more than half his length into me. I almost screamed right then as I felt his hardness spread my buttery depths, but I bit down on the foam in the costume and muffled it.

It was as if his cock met no resistance from my tight pussy. I realized I had gotten very wet along the way. Max moaned in pleasure as he felt my pussy drive itself down onto him. We stood at the doorway, unmoving and a little breathless. I was adjusting to the size of his cock, and he was just standing there, enjoying the feel of my velvet folds.

"Ohhh... oh my god... Max... it hurts..." I moaned incoherently. It felt like a huge rod rammed into me, leaving me completely winded. It was painful despite how wet I was. When I used to make love to my ex-boyfriends, we always spent a lot of time on foreplay to get me adequately relaxed for penetration.

The juices seeping from my tight, relatively inexperienced pussy weren’t enough for a cock of Max’s size. Although I couldn’t see, I guessed he must be at least eight inches fully erect, but I wasn’t in the mood to find out. This is my brother I’m talking about!

He moaned softly, his lips very close to my left ear, his breath tickling me. He sounded seriously excited and in heat now. I was really worried that this would escalate into something more, so I had to act fast. I lifted myself onto my toes again and bent forward in the costume as much as I could to pull my hurting pussy off his large cock.

But as I tried to put some distance between us, he pressed forward with his hips, indicating his unwillingness to let up. I was fuming and frustrated with him. My whole body was shaking, and I was drenched in sweat from my efforts. At least that was what I thought.

Part of me knew my body missed the ecstasy of good sex, and an erect cock buried in my pussy was unquestionably having a reaction on me. But I was unwilling to admit it. I wasn’t about to become a slut for Max! I could feel the heated skin of his tummy rubbing on my fair heart-shaped ass from behind, almost scorching my delicate ass cheeks.

The smell within the costume was a distinct combination of our sweat and my female juices, causing me much embarrassment. He didn’t need to know how aroused and wet my pussy was.

"Ahhh... Zeh... you feel... so good..." he murmured, breathing heavily across the left cheek of my face. He didn’t try to fuck me, but his hands slowly reached down and gripped the waist of the costume, hanging on to it as he tried to pull himself into me.

I wanted to strip that damned costume off right there and then, and put a stop to this before Max went too far. I glanced around the corridor, and I could see no one else. I could only hear a group of kids playing PS3 in the study room next door. If they came out of the room and saw us, they might get curious. I wouldn’t want that.

I grabbed the door frame for support and started to slowly make my way into his room, dragging him along on my tiptoes. That little bastard took the opportunity to stroke his cock in and out of me again as I struggled to walk in front of him.

This time, he pumped me with a couple of near-full strokes as my pussy muscles had somewhat loosened up after my own mishap earlier. I bit my lips to suppress the soft whimpers of pleasure coming from me against my will.

In a few short steps, we finally got into Max’s room. I hastily reached for the door, pushed it shut, and locked it. He was still drowned in lust and not helping. With shaky arms, I immediately pulled off the costume’s head, reached for the zip on the right side of the costume, and desperately jerked it all the way down.

The costume fell away from our bodies, completely soaked and sticky with our sweat. I quickly removed my arms from the inside of the costume and was about to step out of it to end this ordeal when, unexpectedly, Max had other ideas.

He took me completely by surprise when he wrapped his arms around my waist, lifted me off my feet, and stepped out of the costume. As my feet hovered above the floorboard, I felt his hard cock drill even deeper into my pussy. The tip of his manhood was touching me in virgin territory, reminiscent of the night my first boyfriend deflowered me.

However, this time was slightly different. No man had ever gone so deep or stretched me out so much. He was almost buried to the hilt inside me and could have gone deeper if not for my tightness. I had to cover my mouth with both hands as I screamed into my palms from the stinging pain and sensitivity.

Despite the shock from what Max was doing, I couldn’t let anyone find out what was going on upstairs. What would our parents think? We would be ruined! Our lives would be over! How could we face the world? I couldn’t let that happen. I had to stay rational, and I held hopes that Max would come back to his senses. But to my anguish, it seemed like he had completely lost his mind.

I tried to reason with him, "Max! Put me down, please! Don’t do this. I’m your Zeh!" My pleas fell on deaf ears. He carried me to his bed and threw me face down on it. He pressed my butt with his palms and pinned me down. As he slowly drew his cock out of my pussy, I groaned softly into his mattress.

I could feel his burning, lustful eyes looking down at where he entered me when he gasped in awe. He must have been watching my wet pink lips being dragged out as he unsheathed his meat pole. I have been told by my ex-boyfriends that it was quite a pretty sight, and it would always drive them wild.

And the fact that I always kept myself fairly shaven, save for a sexy little Mohawk, could have added to Max’s insane desire. As I felt him vacate my depths, I could also feel my warm, overflowing juices escape from my stuffed female opening, droplets gathering at my pussy lips and running down my inner thighs.

Deep down inside, I was fighting the temptation to drive my ass back onto his cock and ride my wet pussy to orgasm on his thick, hard cock. I was determined not to give in to my bestial urges. I turned my head to the side and saw our reflection in his full-length wardrobe mirror. It had the whole view of his room, and there I was, kneeling on his bed in my sweat-soaked T-shirt and shorts.

My back was arched, my arms were slumped under me, and my long hair had fallen around my face. He was standing behind me in his singlet and boxers, with his cock poking through his fly. That little pervert had forgotten to button his fly before we got into the costume, which led to this predicament!

I could see the left leg opening of my FBT shorts pushed wide to the side as his meat shaft went through it. I could also see his exposed, glistening cock at my wet entrance, raw, obscene, and utterly drenched in my juices. It was like a scene from a porn flick.

His eyes never stopped staring down at my ass as he drew his cock out of my pussy, inch by slow inch. His fingers kept kneading and stroking my butt cheeks. By now, he had already pulled about 6 inches out, leaving only his cock head inside me. But my pussy still felt stuffed. God, he was big.

After he had pulled away, I could feel cool air behind me. Beads of warm sweat rolled down behind my thighs and onto the back of my knees. The heat was getting to him, so he pulled his singlet up, took it off, and threw it to his side.

His chest was rising and falling in anticipation with every breath he took as if he had some sinister plan in store for me. Getting afraid, I tried to crawl forward on my hands and knees to get away from him, but before I could even dislodge his cock from my pussy, he reached down and gripped me at my hips to pull me back.
