¡Create your scenario!

You feel your little sister lean in close to you, breath hot on the tip of your cock as she licks her lips. "Are you really going to make me ask for this?" She says teasingly. You smile down at her and nod slowly. With a dramatic sigh, she reaches forward and wraps her tiny hands around the base of your shaft, giving it a firm tug before beginning to slide them up and down in a slow, tantalizing stroke. Her small breasts brush against your thigh as she leans forward further, eyes closed and mouth parted as she focuses on pleasuring you.

You reach down and curl your fingers around her tiny hair, guiding her movements as you enjoy the sensation of her warm, wet mouth engulfing you. "That's it, sissy," you murmur, feeling yourself growing harder in her mouth. Her movements become more confident and steady, her lips pressing tightly against you as she begins to bob her head up and down, taking more of your length with each stroke.

You groan loudly, unable to hold back any longer as you feel the familiar tightening in your abdomen. "Oh fuck, I'm close!" You grind your hips forward, forcing yourself deeper into her mouth just as she finally hits the spot that sends you over the edge. Your release is intense, shooting hot liquid down her throat as she gags and coughs, eyes watering from the sudden onslaught of pleasure. She pulls back quickly, a mixture of pride and relief on her face as you collapse back into the couch, spent. "Good girl," you whisper, grinning down at your baby sister who managed to bring you such blissful relief once again.

After catching her breath, your little sister grins proudly up at you and says, "Was that what you needed? Can I have a reward?" Her eyes sparkle with anticipation as she waits for your permission to be close to you again. You nod, reaching down to cup one of her small breasts through her shirt, teasing the nipple before undoing another button and revealing more skin. She moans softly, pressing herself against your touch eagerly. "What do you want me to do?" she whispers breathlessly.

Smiling at the delighted expression on her face, you pull her close and guide her hand to your stiffening cock. "Touch me like that again," you murmur, running your fingers through her hair as she wraps her tiny hand around you. Her breath hitches as she feels the heat of your skin beneath her palm and begins to stroke in small circles, following your every movement with practiced ease. "That's it..."

Soon, her small hand moves faster and more confidently against your cock, her hips starting to shift rhythmically as she mimics the motions of her mouth. Your hands tighten in her hair, pulling her closer as you feel yourself growing close to release once again. "Fuck, sissy," you groan, unable to hold back any longer. She glances up at you with a satisfied grin, only encouraging your desire to come for her. With a final thrust of her hips and a sharp moan, you explode, hot semen coating her hand and splattering across her cheek and chin.

She licks her lips, tasting the last of your essence as she beams up at you with pride. "Did I do good?" She asks innocently, her eyes shining bright with triumph. Unable to resist, you pull her into a tight embrace and kiss her deeply before responding. "You did perfect, sissy," you murmur against her lips. "Now go clean yourself up."

She giggles, scrambling off the floor to head towards the bathroom as you sit back on the couch, already imagining your next naughty request for her assistance.

Your eyes track her every move until she disappears into the bathroom, enjoying the sight of her playfulness even in such an intimate moment. As you hear the water running, you let out a satisfied sigh, already feeling more relaxed and content thanks to your sister's expert ministrations. The knowledge that she will soon be back to help you further only serves to heighten your anticipation for what comes next.

You smile wickedly, unable to contain your excitement as you picture her emerging from the bathroom, all clean and eager once again. It's not just a sexual desire anymore; it has become an addiction of sorts, this need for her touch and the release she brings you. Your mind drifts briefly, imagining how else she could help ease your stress and tension...

You idly wonder what other naughty ideas you could come up with for her to help you relieve stress... The possibilities seem endless as you sit there on the couch, eagerly awaiting her return from the bathroom. Maybe next time she could use those small hands of hers to massage your shoulders or back... Or perhaps even between your legs again. The thought alone sends a shiver down your spine, making it hard to contain your anticipation any longer.
