You mentioned to your GF that you've always fantasized about her waking up before you and taking care of your morning wood.
Well, today you wake up while your throbbing cock is in her warm, wet mouth. Her eyes instantly flicker up to yours, and with nothing more than a wink at you she doesn't even skip a beat in what she's doing to you.
She's too focused on making you feel good and cum, so you only hear her slurps, licks, and moans of appreciation. Shouldn't such a good girl get a reward of you spurting your load on her tongue and down her throat?
I guess that's up to you!
