2) This is so tempting, Sis. But wrong.

There was no doubt that Rachel looked hot. She had a rocking body. Not too skinny but no hint of fat. Just lean meat.

Now, to be honest, the animal in me wanted to fuck her until she couldn't take anymore. I'd plow that field for hours and not get bored. It would be hot, sweet and sinful. But, alas, my moral side told me she was my sister.

So, rather reluctantly, I suggested to Rachel. "Rach, don't you think you should get dressed before you catch a cold?"

"But, don't you want to play doctor and nurse, like when we were little?" Rachel slipped a finger into the waist of her panties and slowly drew them downwards, revealing her trimmed pubic hair. "Don't you want to show me how special I am to you?"

"Rach... you are special to me. Always will be. But you know it's wrong ."

"Wrong? You didn't say it was wrong when you made me undress for you all those years ago. You didn't say it was wrong when we both..."

"Wait..." I began to sweat buckets. Shit, I didn't think she would remember that? My voice quivered. "We were both kids, the both of us were just experimenting. We were too young to know any better."

"Back then we might not of known better. But, I still think about that long, hazy afternoon."

Wow, still thinks about it? Those memories had been locked away in a deep cavernous pit in my mind. However, my sister is the queen of manipulation. I had to remain in charge. "But this is different, Rach. Way different."

"How?"

"We've grown up. Look... we'll talk about this when you're sober... And give you time to get over your heartbreak."

"Why does no one wants to fuck me." Rachel stamped her foot and stormed into the bedroom before slamming the door. "I hate men!"

I stood motionless... thinking about my guilty past. "But I was just a kid myself."

I had tried to speak with Rach through the bedroom door, but she continued to ignore me. And after a few minutes, there was nothing but loud drunken snores. But I couldn't get visions of Rach in her pink lacy underwear out of my head. I felt a huge urge to break-out into a furious guilt wank.

I began to tidy away her clothes, but I paused as I picked up her white blouse, then held it to my face and inhaled her sweet scent. She always smelt so nice. So fresh... unless she'd been smoking pot, of course.

I pondered that wank long and hard but in the end, the temptation got the better of me. I undid my belt and unbuttoned my jeans before sitting on the couch. I place her shirt over my face and lay back on the couch, lost in sister's scent.

Pulling my cock through the fly of my boxers I then began stroking myself.

In my sordid dreams, I had Rachel, my little sister, pinned over the back of the couch, fucking her without mercy. Stretching that tight pink pussy of hers. Maybe even slipping a finger into her tight ass while spitting on that stupid fucking tramp stamp she has on her lower back.

In my head, I didn't care it was my sister. In fact, it made it better. We had an unbreakable bond. A deep kinship which no one else could experience or understand.

As I continued to pound Rachel from behind, I swear I could hear her screams in my ears. Begging to have my cum deep inside her.

But before I could build up steam the doorbell rang. But I wanked harder. Hoping to come to a quick finish.

However, it rang a second time. "Fuck sake." I stood up and battled with my stiff cock, trying to **** it back into my boxers as I made for the door. It was a struggle but I just about managed it. "Wait, I'm... I'm coming."

But not in the way I had hoped.

I opened the door. Standing in a black trench coat carrying a large cooking pot, plus having a large handbag slung over the shoulder, was Little Ria. For the first time, she was wearing makeup. Her doe-eyed brown almond face looking the definition of beauty. She had finally come of age. "Oh... Hi."

"Hello, Mr. Mike."

"Er.I thought I told you not to..."

"Well... " Her accent, half American and half Indian, always sounded luscious to me. "I know, Mike. I know. But Rach is my friend. And... "

"The thing is, Ria, Rach is sleeping."

"It's OK. To be honest, I thought she would be. I saw her through the window of the shop. She looked so drunk," Ria peered over my shoulder into the living room. "Can I?"

"You still want to... come in?"

"I need some help."

"Help?"

Ria, usually so shy, pushed past me and strutted into the living room. The clicks of her heels on the wooden floor made my cock hard. I had only ever seen Ria wear tennis shoes. So, it was nice to see her dainty brown feet in glitzy heeled sandals. "I have some chemistry homework, which I would love to help you with. In return, I brought you some food we can share... I also thought some candles to make it special."

"Candles?"

"Yes. I thought you could be my first study date."

To be honest... I didn't know what to say. "Oh. Sure." I felt the back of my neck and followed Ria into the kitchen."But your mum and dad? They know you're here, right?"

"Yes." Ria placed the cooking pot on the dining table, quickly followed by her handbag. She then un-belted her trench coat, followed by undoing the buttons one by one. Slowly, she revealed a dark purple cocktail dress. Her tanned brown pins were on show... just for me. Her petite cleavage just peaking above a tight bodice.

She looked sexy... looked naughty. "But do your parents know you're dressed like this? Cos, I've never seen you so... good. I don't want to get in trouble, Ria."

Ria giggled and thanked me."No, they don't. But don't worry. Pappa is on business and won't be home til tomorrow. Mother is on phone to Aunt Ansoo. She will be busy for three hours or more." Ria then lifted herself onto the kitchen table, where she sat, before slowly crossing her left leg over her right. I didn't quite get a glimpse of her underwear... but I felt turned on, for sure. Ria smiled at me suggestively. "So... Mike what do you want to do?"

"Erm... You mentioned chemistry?"

"About time you realized. I always thought we had lots of chemistry."

I smirked. "Clever."

"So." Ria opened her handbag and pulled out her book. "Let's go over my work before dinner."

We sat next to each other at the table, studying the periodic table. It was a bore. But suddenly Ria rested her hand on my thigh, then leaned into my flank. Her black silky hair tickling the side of my chin while felt dreamy smelling her strong but sweet perfume. My heart pounded. I had always found Ria cute. But recently it was more than that. I found her attractive.

Ria's hand slowly crept up my leg until it found my hard cock, and gripped it tightly. "Hello, Mr. Willy." She giggled childishly. "I've never felt a penis before."

"I think you should stop that before we get into serious trouble."

"Could we have a physiology lesson instead?"

I turned to face her. Her dark eyes large shimmering under the ceiling light. Her hand remained on my ever growing cock. Although I should, I couldn't contain my animalistic nature, which had been teased and tortured all afternoon.

If I couldn't fuck Rachel... I had to fuck Ria. Smash that tiny brown body of hers.

1) Do I give Ria a physical examination? Tease her but don't cross too many boundaries.

2) Tell Ria she better leave. Go and get in bed with Rachel.

3) Fuck her

4) Have dinner first, talk things over - make sure it's what Ria wants.
