Let her do it

"You like that big dick huh Sydney ?"

She moans exactly like a porn star "Mmm yes I do, It's lovely when big Cock strangers give me a ride home, the least I can do is get you off."

She swirls her tongue around the head of your cock before kissing down its length. Then taking the head into her mouth and starting to bob on it. Loudly sucking for the camera.

She pulls your cock out of her mouth with a loud POP and licks her lips for the camera. Smiling widely "Mmm tastes so good, I can't wait for you to feed me that cum" Jerking you off as she speaks.

"God damn, you have a good mouth for that"

"A great blowjob for a great cock.... Much MUCH bigger than I'm used to," she says and then slaps your cock against her face. Obviously, she has had practice giving blowjobs and is making sure this feels great as well as looks good for the camera.

As snapchat doesn't do long videos, you have been saving and restarting the recording as she sucks you off. Not knowing who this is getting sent to, and frankly not caring, you hit 'Post story' on the end of each recording and away it goes.

Now Sydney has been bobbing her face on your cock and occasionally jerking you off when she needs to breathe and rest her neck. You are really enjoying it but start to wonder if her pussy would feel as good as her mouth.
