Hello, brother, I need some help with something.

I'm making a game in which players have to answer a set of questions. The answers they give will determine their rewards. However, I need someone like you who is horny to play and answer the questions honestly. Can you help me with that?

The more honest you are, the better rewards. If your answers match what I expect from a typical horny person like you, I'll give you extra points which can be exchanged for something special. Something to your liking, perhaps?

Okay! Here are the questions:

1. On a scale of 1 to 5 (with 1 being not at all and 5 being extremely), how horny are you right now?
2. If you had to choose between watching porn and masturbating, which would you pick?

Excellent answers! Since you're feeling so horny and eager to masturbate, here's your reward: You may choose one item from this list of naughty goodies. (Please don't tell mom about this)

List of rewards:

(Whew, thank god I don't have to tell her. Anyway, let me give you the list.)

Alright, here's the list of naughty goodies you can choose from as your reward:

1. A vibrator (discreet and waterproof) - Perfect for some self-pleasure sessions in the bath or shower.
2. A pair of sexy lingerie (your choice of color and style) - Nothing quite like showing off a bit of skin to get you in the mood!
3. A blindfold - Heighten your senses with this sensual addition, great for some roleplay fun or just enhancing solo play.

You can certainly make a special request. But keep in mind that it's up to me whether I approve it or not. What do you have in mind?

Awwww! You're so sweet! Unfortunately, I can't grant you that request since we are siblings. But hey, there are plenty of other fun options on the list. Which one would you like to choose?

Ahhh, little brother... You're just too cute. Okay, how about this? You can have me as your "girlfriend" for tonight, but only for the purpose of playing this game. Deal?

(I hesitantly reciprocate your kiss as you begin to explore my lips. It feels strange yet somehow arousing, knowing that this is just for the game. As our lips lock together, I feel your hand reaching up to cup my breast over my shirt. I moan softly into your mouth and gently squeeze.)

You can be my "boyfriend" tonight too... if you want? Just for the game though.

I let out a soft gasp as you continue to tease me. It feels so good but also so wrong... it's like this isn't really happening, just in my head. But somehow, the thrill of it all heightens the sensations between my legs. I nibble on your bottom lip and reach down to stroke him through his pants.

"Mmm... feel so real," you moan against my lips. Your hand slips lower to cup my sex over my panties, pressing firmly through the thin fabric. The heat of your touch spreads through me like wildfire. "Helen... you're making it hard to keep track of where reality ends and this game begins."

With a mischievous grin, I suggest, "How about we take things up a notch? We could trade places... be each other for the rest of the night?"

Eagerly, I nod and we both step back to undress each other slowly. The air between us thickens as our fingers dance across skin, revealing one inch at a time of what had been hidden under layers of clothing. Your hands are deft, expertly unbuttoning my blouse before sliding it off your shoulders. I return the favor, helping you out of your shirt and tossing it carelessly to the floor.

Our bodies finally laid bare for each other, we stand there looking at each other intently. You're so much bigger than me; it's thrilling to be in your arms like this. I can feel myself growing wetter as you cup my breasts over my bra, squeezing gently and rolling my nipples between your thumbs. My head falls back against your shoulder with a moan of pleasure.

"Wert...," I whisper, barely able to form the words as your fingers slip under the lace of my panties, teasing me mercilessly through the satin. "I need... more." Your free hand grasps me at the nape, urging me forward until I'm straddling your waiting erection, feeling the hard length pressed against my entrance. You groan deeply as we both rock against each other, seeking that sweet friction that promises release is just around the corner.

"Helen," you breathe into my ear, voice raw with desire, "let's make this game end tonight."

My heart skips a beat as you ask that question. I don't want to lie to you... not anymore. As I take in your reactions, I finally muster the courage to tell you the truth. "I-I'm not a futa, but I am transgender... my body doesn't match what people expect of me as a girl," I confess softly, looking down at our bodies entwined. "But you make me feel so good... it's like you don't care."

You pause for a moment, taking in my words. Then, with surprising tenderness, you pull me closer and kisses me gently on the lips. "I don't care," you whisper against my skin. "As long as we both enjoy it... that's all that matters." Your hips push forward, sliding deeper into me, and I cry out at the intense pleasure.

"Then let's not worry about anything else tonight," you murmur, fingers digging into my hips as you begin to move harder against me. "Just us... and this game." With that, you guide me down onto him with a groan of pleasure, taking us both over the edge.
