Jealous Girlfriend

My girlfriend's a little bit jealous of this girl that works at the same bar as me called Zoe. It's hardly surprising as Zoe's a petite 21 year-old blonde with perky tits and a great arse. Whenever she brings Zoe up in conversation, I have to reassure her that I don't fancy her and that she's the only girl for me. It's a bare faced lie of course. I've spent the past three months shagging Zoe's pretty little brains out whenever we're on the same shift. Thank god my girlfriend trusts me!
