Liam returned home earlier than usual due to a throbbing headache, deciding to skip his last two lectures. The oppressive heat of the day urged him to head straight for a cold shower. As he pulled off his shirt, he heard the front door open and close with unusual urgency. It was his stepsister, who should have been at her own classes, being in her final year of high school. Her heavy breathing and anxious demeanor suggested something was wrong.Standing in just his underwear, Liam opened the bathroom door and called out,"Hey sis, what's going on? Why are you home early and why do you look so panicked?" His stepsister, visibly flustered, rushed into the bathroom with him, closing the door behind her. She placed a finger to her lips, signaling him to stay quiet, and whispered,"Shhh, be quiet. You’ll find out soon." Moments later, Liam and his stepsister, Emi, heard the front door open again. It was their stepmother Anna, who should have been at work for another four hours. Through the closed bathroom door, they could hear the unmistakable sounds of hushed voices and soft murmurs, clearly indicating she was not alone.Muffled sounds of passionate moans and labored gasps drifted from the living room, unmistakable evidence of what was transpiring mere feet away. Emi's eyes widened as she pressed herself against Liam, both of them holding their breath.

"Fuck, yes! Take me right here!"Anna's lusty voice rang out."We're all alone until the kids get back." A loud smack followed by a low groan indicated things were escalating rapidly. Emi trembled against Liam, her cheeks flushed crimson. He could feel her racing heartbeat pounding against his bare chest.This was beyond inappropriate - eavesdropping on his stepmom getting ravaged by God knows who in their very own house. Yet morbid curiosity kept them rooted to the spot, straining to catch every lurid detail.The obscene symphony intensified, with Anna's shameless cries echoing off the walls."Yes, yes, YES! Fuck me harder!" Emi squirmed against Liam, quivering with barely restrained arousal. Her delicate fingers crept down to cup his firm buttocks.

Emi's body tensed up when she felt Liam's member brushing against her bottom. Despite knowing they shouldn't, both teenagers couldn't help but revel in this forbidden moment.Her gaze flickered towards the sound coming from the living room before quickly returning to meet Liam's eyes. A mischievous grin spread across her face, revealing her perfect teeth."So," she purred, leaning forward ever so slightly, her breasts pressing against his arm, "you like what you hear too, huh?"

Emi giggles playfully, unable to contain her excitement. She arches her ass further into Liam's grip, silently begging for more. Their bodies continue to dance erotically, synchronized by desire.

Emi feigns pain loudly, letting out a dramatic moan followed by a soft whimper. Her head falls limply onto Liam's shoulder, giving him full access to her exposed neck. He could feel her heart racing wildly underneath her thin shirt, betraying her true feelings.
