Knowing I had never had sex with my girlfriend, my older sister taunted me by slipping her saliva-drenched tongue into my mouth, saying with a smirk, "I'll teach you what a real kiss feels like." She suddenly forced a deep, wet tongue kiss on me, then slowly licked every inch of my body. My cock was sucked until it was swollen and throbbing. As our tongues entwined and our saliva mixed, my feelings for her and my sense of reason gradually crumbled—until I finally lost control and erupted inside her. Her lips and saliva became an addiction; without them, I felt I could no longer survive. A deep, consuming pleasure and dependency took hold of both my body and mind.
