"Alex… I'm your sister…" Lucy moaned weakly, her voice trembling with shock and forbidden arousal. Yet her body betrayed her, she melted back into my touch, her ass subtly pressing against my cock.
"Yeah, sis…" I whispered into her ear, my voice dark and hungry. "Won't you help your brother?"
I moved my cock around her hips, deliberately sliding the thick, veiny shaft along her soft skin so she could see and feel just how massive it looked compared to her body. The head leaked precum onto her belly as I teased her, showing her exactly what was going to stretch her.
Lucy's breathing grew faster, her plump breasts rising and falling rapidly as she stared down at my cock in a mix of fear and undeniable desire.
Nadia watched the entire scene with lust-filled eyes, her own hand unconsciously sliding between her thighs as she witnessed me claiming my cousin right in front of her.
