The sun was setting as I emerged from the back door, carrying a bottle of wine and two glasses. The pervy family hot tub in our backyard was already bubbling, inviting me to relax after a long day. I stripped down, letting the cool evening air caress my skin before I slipped into the warm water for some step family sex.
“Shit,” I heard a soft voice say from behind me. I turned to see my step-sister, Ella Cruz, watching me from the edge of the patio. Her eyes widened as she took in my naked form. “Ella, what are you doing here?” I asked, trying to maintain a casual tone.
She hesitated for a moment before stepping closer to the hot tub. “I saw the lights on and thought you might be out here. I wanted to talk to you about something.”
I leaned back, watching her intently. “Sure, what’s up?”
Ella looked around nervously, then began to unbutton her blouse. “Mind if I join you? It’s been a long day.”
I raised an eyebrow, surprised by her forwardness. “Of course, come on in.”
She slipped off her blouse, revealing a lacy bra that barely contained her pert breasts. My cock twitched at the sight, and I quickly looked away, feeling a pang of guilt. Ella was only 21, and I was her older step-brother, but the sight of her half-naked was driving me crazy.
She stepped out of her jeans and panties, leaving her in just her bra and heels. My eyes trailed down her body, taking in every curve. She stepped into the hot tub, the water lapping at her waist.
“You look different,” I said, trying to distract myself from her body.
She smiled, running a hand through her long, dark hair. “I got a new haircut today. Do you like it?”
She reached over, her fingers tracing the water’s surface. “That’s a shame. You should take some time for yourself.”
I looked at her, feeling a spark between us. “Maybe you’re right.”
She leaned in, her voice soft. “You know, I’ve always thought you were one of the most attractive men I’ve ever seen.”
I raised an eyebrow, surprised by her admission. “Ella, you shouldn’t say things like that. We’re stepsister and stepbrother“
She smiled, her eyes gleaming in the soft light. “Why not? It’s true.”
She reached out, her hand wrapping around my cock under the water. I let out a groan, my body responding to her touch. “Ella, we can’t,” I protested weakly.
She stroked me gently, her grip firm. “Who says we can’t? We’re adults, and we’re not related by blood. Besides, I’ve wanted you for a long time.”
I closed my eyes, giving in to the pleasure. “Fuck, Ella, you’re playing with fire.”
She leaned in, her lips brushing against mine. “I like it hot.”
She climbed onto my lap, straddling me. I could feel her heat through the thin fabric of her bra, and I groaned again. She ground against me, her breath coming in short gasps.
“Ella, we can’t do this step family sex,” I said, my voice hoarse with desire.
She smiled, her hips moving against me. “Just one taste, Sebastian. Please.”
I couldn’t resist any longer. I pulled her to me, my mouth crashing against hers. She moaned, her tongue meeting mine as we kissed. I slipped a hand behind her, unhooking her bra and letting it fall away. Her breasts spilled out, and I groaned again, taking one nipple into my mouth.
She cried out, her hands tangling in my hair. “Oh god, Sebastian, that feels so good.”
I sucked and licked her nipples, my cock throbbing between us. She reached down, guiding me to her entrance. I slipped inside her, both of us moaning at the sensation.
“Fuck, Ella, you’re so tight,” I groaned.
She began to move, slowly at first, then faster. Water splashed around us as she rode me, her breasts bouncing with each movement.
“Oh god, Sebastian, you feel so good,” she moaned.
I reached up, cupping her breasts and pinching her nipples. She cried out, her movements becoming more urgent.
“Harder, Sebastian, fuck me harder,” she begged.
I obliged, my hips thrusting up to meet hers. The water sloshed around us, but neither of us cared. All that mattered was the feel of her tight pussy squeezing my cock.
“Oh god, Sebastian, I’m close,” she gasped.
I reached between us, rubbing her clit as I fucked her. She threw her head back, her body tensing as she came.
“Sebastian, oh god, Sebastian,” she cried out, her body convulsing around me.
I couldn’t hold back any longer. I pulled out of her, my cock throbbing in my hand. I came hard, my cum splattering across her stomach and tits.
We sat there for a moment, panting and covered in water and cum. Ella looked at me, a smile playing on her lips.
“Well, that step family sex was unexpected,” she said.
I laughed, pulling her to me for a kiss. “Unexpected, but fucking amazing.”
We stayed in the hot tub for a while longer, our bodies pressed together as we kissed and touched each other. Eventually, we got out, wrapping towels around ourselves and heading inside.
As we dried off, I looked at Ella, a sense of wonder and disbelief washing over me. We had crossed a line, one that we couldn’t uncross. But in that moment, I didn’t care. All I knew was that I wanted more of her.
