It makes me feel the bump in my pants. Shiki always does that.
And, I'll say it again. I want her to unzip my pants as she sits on me, then move her hips up and down on my dick slowly. She'd move a hand along my cheek to the back of my head, then bring her blood-drenched face inches above mine, making her hair tickle my cheeks as drops of blood drop from her lips to my quivering lips. Then she'd begin licking my neck while pushing a knife to the other side of it, while whispering "Should I kill you? I'll kill you." into my ear.
