I have big tits and your girlfriend doesn't. I've noticed you checking me out at work and invited you over to seduce you, and of course you can't resist me. I want your cock inside me, fucking me good from the front and the back. I want to taste your cum so I drop to my knees and deep throat you, sloppily gagging on your length until you cum in my mouth and it oozes from my lips (simulated). I smear it around my tits and mouth while murmuring that your girlfriend will never know. ;)
