"Then fucking do it," came a voice from the other side of the door, low and amused.

We both froze as Russell sauntered in, tall and lean with a wry smile playing across his lips. My sister's boyfriend. I panicked and tried to pull back, but she kept her grip firm in my hair.

"Don't stop now," he said, closing the door behind him and leaning casually against it. "This is the hottest thing I've ever seen."

My heart pounded as he stood there, his dark eyes taking in every detail of our tangled bodies. I never imagined being caught like this would be such a turn on. My sister gave a breathy laugh, and I felt her relax beneath me.

"You like watching me get off, baby?" she asked, still panting from her nearness to orgasm.

Russell approached the bed like a cat on the prowl. His boldness rivaled hers, and he made no effort to hide how much he was enjoying this, He smirked, coming up behind me as I hovered over my sister’s pussy. “Need a hand?” He undid his belt and let his pants fall to the floor, then climbed onto the bed beside us.

My sister moaned as Russell grabbed her tits and squeezed them with familiar roughness. She reached back and wrapped her fingers around his hard cock, stroking it slowly while looking at me with eyes half-lidded in ecstasy.

I sat back on my heels, dazed and exhilarated by what I had just done—and by who I had done it with. She lay sprawled across the bed, flushed and still panting heavily. For a moment I thought she might fall asleep.

Instead she looked at me with droopy-lidded eyes and gave me a wicked grin. "Holy shit," she said softly, her voice shaky but teasing.

my sister sat up to pull Russell in for a deep kiss. I felt a rush of wetness between my legs as their tongues danced together.

Her voice was muffled against his mouth. “I found the cutest little pussy in my brother’s room.”

He chuckled, low and sexy, then turned his attention toward me. “I'm surprised your brother pulled such a fine piece of ass,” he murmured, pulling me up from my knees and into an aggressive kiss. I was dizzy from the intensity of it all—the taste of my sister still on my lips, the heat of Russell’s body pressed against mine, his cock growing harder by the second.

I kissed back
