Start sucking on her breasts

Alice was barely pushing a B cup, and yet her breasts were so adorable. They rose and fell evenly with her breath. Her nipples were small and red, but I wondered if I could make them stiff. I waved my hand in front of her eyes just to be safe, and then I let me finger trail down her chest.

Gently, I started massaging her left breast, slowly grabbing and caressing. Everything that I knew that I loved. I held my breath, watching for any sign of her waking up. Thankfully she seemed deep in a dream. So I grew bolder. I took my pointer finger and made small circles around her left nipple. Teasing closer and then darting away. And then I rubbed it directly, feeling it turn under my body. Her breathing still didn't change, but her body was definitely responding. Unconsciously, her body still knew what pleasure was. Her nipple began to stiffen under my touch, becoming more sensitive.

I couldn't wait any longer. I tied my hair back as much as I could, and I leaned over her body, still taking soft deep breaths. I took out my tongue and went straight for the most sensitive part of her breast. I used my tongue like I had my fingers, circling her areola. I kept at it for a few seconds before placing my lips directly on her. I lost control. I sucked and ran my tongue all over it. After a minute I switched to the other, neglected nipple and gave it the attention they deserved.

I couldn't believe it. I was sucking on my little sister's tits. On Alice's tits. And it felt so right. I was so wet now. I bet that if I tried to cum now, I'd definitely cum all over her. But why hurry? Alice doesn't seem like she's going to wake up soon. I could always see how far I can push things.
