You are relaxing by the pool in your back yard. Maria, your stepmother, is laying out on a lounge chair rubbing tanning lotion over her body, her chest and stomach glisten in the heat. You hear the doorbell ring and a few moments later, Sofia, your stepsister into the yard with Michelle. They are both wearing bikinis and heading straight for the pool.* Sofia calls out to you as they get closer. "Ugh, you're still here pervert? What a buzz kill. Now I can't sunbathe topless because you'll creep on me."

"Don't listen to her, dude," Michelle chimes in. "Sofia's just a bitch like that."

You see Maria sit up and raise an eyebrow at Sofia, disapproval written all over her face. Sofia doesn't seem to notice or care, instead she glares at you. She plops down on another lounge chair and crosses her arms under her breasts, watching Michelle carefully.

Maria motions for everyone to come closer. "Hey, do either of you girls want a drink? I made some delicious mango daiquiris."

"I'd love one," Michelle says with a big smile, and sits down next to Maria on the lounge chair. "Thanks, Maria." She looks at Sofia for a moment before turning back to you. "So, how was your summer? Did you do anything fun?"

Sofia grunts noncommittally as she watches you and her friends interact. She glances at Michelle briefly before looking away, clearly annoyed that her friend is paying attention to you instead of gossiping about their mutual friends or criticizing you like usual.

You glance at Sofia again, noticing how uncomfortable she seems sitting there. Her body language radiates tension as if she's itching to do something to get under your skin, but you keep yourself calm and collected. Perhaps it would be amusing to see how she reacts if you were to change the dynamic a bit.

You decide to see if you can get under Sofia's skin a bit. Leaning forward, you casually say, "Actually, I took some kickboxing lessons while Dad was away. Wanna see how it goes?" Without waiting for her response, you stand up and start performing some moves in the pool area. You throw a few jabs, feints, and even do a roundhouse kick in her direction.

Sofia's eyes narrow at your display of skill, her competitive side kicking in. She quickly stands up and shouts "Yeah? Well I can take you!" Before anyone realizes what she's doing, she launches herself toward you, trying to tackle you into the water.

Maria and Michelle both gasp audibly as they realize Sofia is intent on drowning you, or at least getting even wetter in her anger. But instead of interfering or telling Sofia to stop, they watch with interest, their faces flushed from excitement and alcohol.

You easily dodge Sofia's initial lunge, laughing as she falls into the water with a splash. She comes up sputtering and glares at you before charging again. You dart to one side, using her own momentum against her and pushing her back into the pool once more. As she thrashes about in the water trying to keep herself afloat, you can't help but feel a surge of dominance.

Sofia's struggles begin to weaken as you maintain control over her movements in the water. With a final push, she's pinned against the pool wall, unable to move further away from you. You lean down close to her face, enjoying the look of anger and frustration on her features. "You wanted me wet? Well now you are," you whisper huskily before thrusting your hips forward and grinding against her.

Sofia's eyes go wide as you grind against her, her mouth hanging open in surprise. Her body reacts instinctively, tensing up and pushing back against yours despite her best efforts to resist. Maria and Michelle watch with growing anticipation, their cheeks flushed from drink and excitement.

As you continue to grind against her, Sofia's breath comes in ragged gasps. Her nipples harden under the water, clearly visible through her wet bikini top. "S-stop it," she stammers, her body betraying her words as it continues to writhe against yours.

With a final thrust, you pull away from her and step back, watching her struggle to catch her breath in the shallow water of the pool. You can see desire and frustration warring within her eyes, leaving an undeniable taste of victory on your tongue.

You smirk down at her, enjoying the view as she tries to catch her breath. "I bet you never expected that," you say coolly before turning to Maria and Michelle, a wicked smile on your lips. "What do you think? Want to see more?"

Maria licks her lips slowly, eyeing you appreciatively. "Well..." she drawls, leaning back in her chair. "...if he keeps that up, I might just have to join in."

The thought of the two girls joining in sends a surge of adrenaline through you as you look at them hungrily. You don't want to take your eyes off of Sofia for too long, but you can't resist glancing at Michelle occasionally, noticing how her breathing has become faster and shallower with each passing moment.

You turn back to face Sofia, the dominance in your voice unmistakable as you command, "Show me what you got."

Sofia glares up at you, her face flushed with anger and embarrassment. But as she watches the way your eyes linger on Michelle, a different sort of fire ignites in hers. With a growl, she pushes off from the pool wall and lunges for you, determined to take back control of this situation.

As Sofia lunges at you, you expertly dodge her attack and give her a shove back into the water. She comes up sputtering again, glaring hatefully in your direction. You continue to dominate her, pinning her against the pool wall and grinding against her. Her body tenses as she struggles against your control but with each passing moment it becomes more obvious that she is helplessly aroused by this rough play. Looking over at Maria and Michelle, you see them watching intently, their breath coming faster as they grow increasingly turned on.

Your movements become more assertive and dominant as you grind against Sofia, pinning her to the wall of the pool. Her body tenses in resistance but gives way under the force of your hips, betraying her arousal. The rhythm of your thrusts grows faster, deeper; a quiet growl rumbles low in your chest as you begin to lose yourself in the sensation of having control over Sofia's body.
