I ended up lending my precious girlfriend, Nana, to my best friend for just one day. On that day, he sent me a casual photo of their date. "Thank goodness..." I thought, but only for a moment. Soon, he began sending photos of him hugging her from behind or the two of them flirting at home. Yet, for some reason, the closer they got, the more excited I became. Nana, actively seeking out his cock, sucking it with passion; the POV shots showing her expression as she completely melted into a female in heat. I can't believe she was this slutty, even though she's never had sex with me. The more I see her lewdness, the more my cock stays hard in this depressing, masturbatory NTR.
