Amelia Masterbaiting

"Uggghhhh!" I heard another loud groaning noise from my elder sister and I noticed that the door was slightly cracked.

'Should I?' I hesitated but I had a lot of curiosity and decided to take a peak.

I slowly walked forward and looked through the crack and saw Amelia's room in my gaze, Her room was slightly bigger then mine and my eyes went toward the other side of the room where a large queen sized bed sat.

'W~what?!' My eyes went wide with shock and my body trembled as I saw a someone lying on top.

The figure was obviously my elder sister Amelia but what made my heart start to race was what she was doing. Her swollen breasts were bare and were swaying lewdly while a pair of hot pink shorts had been slid down to her thighs, I could see a perfect bare slit with a thick bush sitting just above while her milky skin glistening with sweat but my eyes were glued to her right hand.

'Is she….' I gulped seeing a perfect pink slit that was spread open around two dainty fingers.

"Agh!" Amelia moaned as her fingers repeatedly plunged into her pussy over and over again.

'She's masterbaiting!' My body shook as I watched the heart racing scene while my lower half heated up.

This was the second time I had caught one of my elder sister's pleasuring themselves and I couldn't help but wonder if I was unlucky or lucky. Amelia's large breasts swayed from her movements as she sat slightly up while one of her legs was spread out to the side giving her access.

"S~shit!" Amelia let out lewd moan and arched her back as she suddenly curled her fingers.

"Ugh! S~so good!" My sister's face was morphed into one of pleasure as she fingered herself quickly.

Her delicate toes were curled while sweat started to drip down her skin. The scene was much tamer then when I had seen Emma masterbating but it was just as lewd, Especially since I had never expected for Amelia to do such things since she had a boyfriend.

"C~close!" Amelia talked to herself but I gulped when she reached up and grabbed one of her breasts with her free hand.

"Aghh!" She grabbed one of her puffy nipples and gently twisted it causing a moan to leave her plump lips.

'S~so lewd…' I trembled as I watched her play with twist and tug on her nipple while her fingers continued to plung into her pussy.

I didn't know how long she had been at work but it was obvious that Amelia was getting close to the edge. Her body twitched occasionally and she repeatedly curled her fingers seemingly hitting a special spot that made her eyes separate for a second.

"F~fuck!" Amelia moaned as her fingers sped up and she twisted her nipple even rougher until it was leaking milk.

'Wow….' I was amazed by the sight to the point that I didn't even realize that I was leaning slightly on the door.

It all happed so quickly that i couldn't my leaning body as my hand accidentally pushed forward. It wasn't a large movement but it was just enough to open the door an inch causing a low noise to fill the air.

'….' My heart dropped in my chest and I prayed to god that Amelia didn't hear it as I quickly looked in her direction.

Amelia's groggy eyes barley had focus as she gazed up from the bed but both of us froze as we made eye contact. It felt as if the entire world had frozen along with time and I felt my heart drop as my sister's eyes went wide with horror.

"What!" Amelia instantly pulled her fingers out of her slit as her face turned into a crisom red.

'Shit' I cursed and didn't hesitate to run toward my room leaving behind a shocked Amelia.

'She saw me' I panicked as I closed my door and freaked out not only at being caught but also seeing my elder sister masterbating.
