The low rumble of tires on the driveway cut through the quiet afternoon like a warning shot straight to my chest. I stood frozen at the front door, palms slick with sweat, heart slamming against my ribs hard enough to make my vision pulse. Mom’s last text still glowed on my phone screen: Be nice and help Aunt Tara with her bags, okay? She’s family. Family. Right. As if that word hadn’t already started twisting into something filthy in my head the second I knew she was coming.
The engine died. A car door clicked open, then shut. Footsteps—confident, unhurried—crunched up the porch steps. I wiped my hands on my shorts and forced a casual smile, the kind that felt like it might crack my face in half. The door swung wide and there she was.
Step-Aunt Tara.
Thirty-six, divorced eight months, and built like every guilty fantasy I’d ever tried to bury. A thin white tank top clung to her skin from the summer heat, damp in places where the fabric had stuck. No bra. Not even a hint of one. Her 38H tits—God, I hated how precisely I knew that number from overhearing Mom once—swayed heavy and full with every step, the soft weight of them shifting under the thin cotton like they had their own gravity. Her long dark hair fell loose and a little messy from the drive, strands sticking to the curve of her neck. Tight black yoga pants hugged her wide hips and thick thighs, the material stretched so tight it outlined every lush inch.
She dropped her purse with a soft thud, arms opening wide, that sweet, warm auntie smile blooming across her lips. “Ryan, sweetie!”
Before I could even say hi, she pulled me into a hug. Not the quick side-squeeze kind I remembered from holidays. This was full-body, chest-to-chest, her arms wrapping around my back and holding on like she meant it. Her massive breasts crushed against me instantly—soft, warm, impossibly heavy—squashing into my chest with a plush give that made my breath catch. The heat of them radiated straight through her tank top, soaking into my shirt, and I felt her nipples stiffen right against me, two hard little points dragging across my sternum as she settled in deeper.
Fuck.
Her scent hit next—vanilla-cherry body lotion mixed with the faint, clean sweat of a long drive. Sweet and warm and way too intimate. My cock twitched hard in my shorts, thickening against my thigh before I could stop it. I tried to pull back, but she just held tighter, rocking me gently side to side like we were slow-dancing. Each little shift made those heavy tits drag across my chest again, the soft flesh molding and bouncing lightly with the motion.
“Ryan, sweetie, you’ve gotten even taller since last Christmas,” she murmured against my ear, voice low and throaty, breath warm on my skin. “Come here and give your favorite aunt a proper squeeze.”
She hugged me again, harder this time, her body pressing flush. My hands hovered awkwardly at her waist before I let them settle on her lower back, feeling the dip of her spine and the flare of her hips. My cock was fully hard now, throbbing painfully against her stomach, and the guilt crashed in like ice water—this is your step-aunt, you sick fuck—but it didn’t stop the blood from pounding south. She laughed softly, that low, knowing sound that vibrated through her chest into mine, and finally stepped back.
But not before one of her hands “accidentally” brushed down my side and grazed the front of my shorts. Just for half a second. Long enough for her fingertips to feel the rigid outline of my erection. Her eyes sparkled with that playful glint I’d always remembered, but there was something new in them now—something darker, hungrier.
“These bags are heavier than they look,” she said, smirking as she glanced down at the suitcases by her feet. “Be a good boy and help me unpack a few things?”
