Pool Party8/31/2025, 10:59:56 AM

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."

No I won’t

"Of course not," you reply sarcastically as they begin to climb the steps into the pool. "Anyway, I invited Michelle over, she just got back from Europe and had some crazy stories." Sofia rolls her eyes at you before taking a seat on the edge of the pool, soaking her feet in the water. "Yeah yeah, I heard all about it," she says dismissively. "Let's hear something new."

I get in the pool

Pool Party8/31/2025, 11:01:29 AM

You climb into the pool as well, leaving your father's beer on the side of the pool, then swim over to Sofia and sit next to her, splashing water in her face playfully. "Well, what do you want to hear? Anything in particular?"

"I don't know... anything crazy I guess," Sofia says as she leans back against you. "You know, like sex with a random stranger on a crowded beach or something." She shoots a sideways glance at you while saying this, her breath tickling your neck.

You feel Sofia's body pressed against you as she leans back, her breasts almost brushing against your arm. You think about how close you used to be with her before Maria came along, and the jealousy wells up inside of you. Maybe it's time for some payback.

As Michelle begins to share some of her more outrageous stories from Europe, you lean back further into Sofia, pressing your growing erection against her leg as she wiggles uncomfortably. You know she feels it, but she tries not to react too much in front of your father's beer and Michelle. This only makes you harder.

She feels that I’m in a chastity cage

Pool Party8/31/2025, 11:02:56 AM

As you begin to push against her more aggressively, Sofia looks over at Michelle nervously. She hadn't realized just how turned on you were until now. Trying not to make a scene, she quietly asks Michelle if there are any condoms in her bag. Her heart races as she waits for the reply.

Sofia bites her lip anxiously as she waits for Michelle's answer. She can feel your erection against her leg, the outline of your hardness clearly visible through the fabric of your swim trunks. Her body responds involuntarily, her nipples hardening and her pussy growing wet.

"Um... I don't think so," Michelle replies nonchalantly, oblivious to the tension in the air. "But we could probably find some around here if you want?" she adds, grinning mischievously.

I can’t I’m locked in a chastity cage

Pool Party10/19/2025, 7:26:42 AM

Sofia lets out a small laugh, shaking her head at your joke. She hopes this means you're not serious about the chastity cage thing, but she can't help feeling aroused nonetheless. The fabric of her bikini bottom is becoming transparent from her wetness as she squirms on the edge of the pool, trying to find some relief from your increasingly aggressive advances.

"Oh come on," she teases you, leaning closer and running a hand through your hair before retracting it quickly when you let out another grunt. "It's not like I want this anyways." She gives you a sultry look from under her eyelashes, trying to keep herself composed while secretly wanting nothing more than for this moment to go on forever.

User#175663790009110/19/2025, 7:28:33 AM

My step sis has the key she said my dick is to pathetic to be unlocked

Pool Party10/19/2025, 7:28:33 AM

Sofia chuckles again, unable to resist teasing you further despite the growing discomfort she feels beneath her swimsuit. She leans even closer and whispers into your ear, "Then maybe it's time I gave you a taste of what I could do with my key?" Her hot breath tickles your neck as her hand wanders lower on your body, tracing circles over the bulge in your trunks. "I bet I could make you feel really good."

Her fingers slide into the waistband of your swim trunks and begin to tug them down, revealing your hard cock to the warm sunlight. It throbs eagerly as she looks it over, her eyes traveling up and down its length before meeting yours again in a sultry gaze that promises satisfaction if you let her continue.

User#175663790009110/19/2025, 7:29:35 AM

Please my cage is getting tighter just ask her for the key

Pool Party10/19/2025, 7:29:35 AM

Sofia can't help but feel excited by the thought of taking control in this situation. She glances over at Maria and then back to you before leaning forward, capturing your lips in a hungry kiss. Her tongue darts out to tease your mouth as her hand continues to stroke your cock, granting you small releases of tension.

Meanwhile, her other hand slips under the waistband of your trunks and finds your bare ass, squeezing and massaging it roughly. Her movements become more urgent, her need for satisfaction growing with every passing moment as she relishes in the power she has over you.

User#175663790009110/19/2025, 7:30:24 AM

Fuck it’s starting to hurt I’m gonna cum

Pool Party10/19/2025, 7:30:24 AM

Sofia breaks their kiss and looks down at your cock, her eyes widening in surprise as she feels you beginning to cum. She expertly jerks you off until you shoot your load across the water, spraying hot liquid across both of their legs before coming to a stop. As your orgasm subsides, she smirks victoriously and releases you from her grasp.

"There," she says breathlessly, running a hand through her wet hair. "I think that made everything better." She glances over at Maria, who has been watching the whole exchange with equal parts amusement and horror on her face.

Meanwhile, your erection begins to subside as you finally catch your breath again. "Wow," you say with a grin. "Guess I didn't need that chastity cage after all."

User#175663790009110/19/2025, 7:31:57 AM

Fuck can’t believe I came in a chastity cage

Pool Party10/19/2025, 7:31:57 AM

Sofia rolls her eyes as you complain about coming in the chastity cage. "It's not like it matters," she shrugs, moving closer to Michelle. "Anyway, I bet we could find some actual lubricant if you need it later." She winks at you and takes a sip from her drink, enjoying the look of frustration on your face as she does so.

The tension between Maria and Sofia remains palpable even after the sexual encounter has subsided. They both know that things have changed now, but neither is quite sure how to react or move forward in this new dynamic. The pool party continues with varying degrees of awkwardness and discomfort for all involved.
