It's still dark, even after I open my eyes.

I feel dizzy especially … after everything that happened with the girls.

What a crazy few days.

I can say I've been tied to a chair.

"Hello? Anybody… home?" I cry out.

"Please keep your voice down. They might hear you."

It's my sister.

"B-Big sis…?" I call to her.

She lights up a match. It reveals my sister's face: the same long blonde hair, the same dash of freckles, the same cute button nose and thick pouty lips. Her green eyes are filled with concentration.

Ah, maybe she will help me make a sense of this mess. I think so. My sister is still immune, isn't she? I don't really want to put the moves on her.

Really: this ring is more troublesome than it is worth.

And yet, I reach for it, feeling the black band of metal against my middle finger.

"That's me. Glad you remember," she chuckles. "What did those girls do to you? Goodness, you are all bruised… and are these… hickeys?"

"I… I don't know. I can't see."

The match she is holding is making just enough light to make out where we are: our home's basement.

Thankfully, my sister seems determined to protect me. I know she's not like the others, she would ever fall crazily in love with me and the ring would have no power over her.

I am sure.

Haha, perfectly sure.

"Here, drink. You must be parched."

She passes me a bottle of water and I chug at it. It tastes refreshing, if a little too sweet. My big sis is studying as a professional chemist and herbalist and she can make the most amazing concoctions. She looks at me intently as I finish the bottle in one swing.

"That's good. Good boy," she chuckles, prying the empty bottle away from my hand. As she does so, our fingers touch and I feel a lightning jolt pass between them.

"How do you feel?"

"Uh. Good. I feel good."

"You are about to feel so much better," she growls, pushing me against the chair. She straddles herself on my lap.

I feel so weak all of a sudden, so… dizzy.

What's going on?

I glance at the ring and I feel a faint woman's laughter echo through the room.

Oh no.

The match goes off.

She scratches another one alight and holds it close to my face. I can count her freckles and the specks of light in her deep emerald eyes. She smiles at me, feverish, her cheeks growing flush. She is so beautiful, but she is my sister.

And if the ring got her as well…

"I never noticed how precious you are, little bro. How hot."

"P… Please… t-take off my ring…"

"Shut up and look at me!" She barks, grabbing my chin and forcing it so I can look at her. Only her. "Oh, that's better. Much, much better." She starts panting hard as a grin stretches her plump lips. "You have to look at me, do you understand? Only at your big sister who loves you very much… very, very much… your skin tastes delicious, did you know?"

She rubs herself against me.

"I'm so hot. So fucking hot for you, lil' bro. I need you…" she shifts on my lap, starting to grind her crotch against my stiffening cock. I am trying to hold it in, but I can feel how moist and how wet her pussy is becoming through the thin fabric of her black panties. "I need you inside me. Hot and hard. Can you do that for me?"

I am starting to feel dizzy, but I can feel my dick strain against my pants and also my sister's pointy nipples against my chest feel so stark. What did she do to me?

I thought she was trying to make me sleep, but…

The match goes off.

This time she does not use another one.

"Do you like it?" She chuckles as she leans forward and licks my neck. I groan, unable to stop her assault. Her tongue feels like fire! I shudder under her grip. She coils her arms over my neck and keeps licking.

"Ah… ah… please… sis… please! Please take… take off my…"

"You pants? I want you to take that big cock of yours and put it deep into your sister's little honeypot. Be a good little brother."

"No… you are like… like the others…"

"What the hell are you talking about?" She stops grinning and chokes my windpipe. "What other women? Do you want to leave your sister for other women? Do you want me to get… mad?" She leans forward, her voice like poisoned needles against my ear. "Because I can get pretty mad, my beloved brother. And then you will understand you need your big sister just as much as she needs you. As she needs your big fucking cock inside her. Right. Now!"

I nod. That's all I can do.

"That's better. That's a good boy. Good boy. You love your big sister, don't you?"

I nod again.

"More than any other ugly woman in the whole wide world. More than that fat bitch of your teacher, more than that ugly tomboy of your childhood friend, and more than that filthy whore of the popular girl at your school… do you?"

"Y-yshs!" I groan through her grip.

"Ah, thank goodness. I'm glad." She chuckles. Through all this, my erection has only grown stronger. "So how about we start with a nice little blowjob, hm?" She lowers herself to her knees and I can feel and hear her tinker with my belt.

She's about to do it. And all because I picked up this cursed ring.

There must be a way to get out of this, but…

"Hhhgh," I groan as I feel her hot breath against my cock.

I can't seem to find one.

And once again, that damn laughter echoes through the room… something only I can hear.

If only Grandpa had found a better present for his nephew...
