Sis gets naughty and anal-ready during dorm study break

Nothing kills time during late-night study sessions quite like a naughty break, and my sister knows just how to spice things up. As I was flipping through my textbooks, she playfully teased me about her wild side, hinting at some secret desires. I couldn't resist the urge to satisfy her curiosity, and soon found myself pleasuring her with my fingers, exploring every inch of her eager body. But that wasn't enough to quench our shared thirst for excitement. With a mischievous glint in her eyes, she hinted at wanting more, and I obliged, pushing a snug buttplug deep into her inviting hole. The sensation was overwhelming, driving us both to the brink of ecstasy. As we continued our passionate exploration, I couldn't help but admire her luscious curves, from her plump pussy to her ample ass, glistening with sweat and anticipation.
