At least, that's all she said until the caught her breath. Her cock still laid deep inside of me minutes after. "Anna," she began, her voice soft, "what did we just do?"

I kissed her neck sweetly. "Made love."

As soon as Elsa began to squirm, I fell into a panic. When I pulled her out of me, her worried eyes poured into mine. "I think we made a mistake." I didn't reply. I couldn't. I'm fairly certain I had just fallen in love with the way my sister fucks me and she's backing out.

Elsa scooched her way off the bed and grabbed her pants. "This is wrong," she said, slipping one leg on at a time. "We're sisters." The blonde fastened her belt. "I should have listened to my gut." She threw on her shirt and headed to the door. "We have to swear to each other that this will never happen again."

My lips wrenched in. I slowly nodded my head and choked back a tear.

"I'm sorry. I really am. I shouldn't have led you on like that." She furrowed her eyebrows and smiled tenderly from my doorway. "Are you okay?"

"Yeah," my hoarse voice trembled out.

I caught the kiss my adorable sister blew and held it, smiling as she left.

Once the door clicked, I pressed her kiss to my lips. My body collapsed onto my mussed sheets, unable to move or speak. Only cry with every inhale I took in Elsa's scent.

I still felt the remains of our love boiling inside of me. She was a part of me now. A part of me I wasn't willing to let go.
