Finish in her mouth

You decide that discretion is the better part of valor for the first night, knowing full well you'll take advantage of your girlfriend's proclivities for exhibitionism on the beach.

"May I please cum in your mouth?" you ask. Jess pulls off and looks up at you. She lets her tongue fall out of her mouth and slowly strokes you off.

"Actually, I'm going to let you watch all of your sticky cum fly into my mouth so you can see it. Then I'll swallow it. Go ahead and cum John."

"Take it all. Fuck, Jess. I love that you've become such an amazing cocksucker. Here it comes," you groan. Jess passively lets you fill her mouth, your cum landing on her tongue. She moans, obviously surprised by the volume but dutifully continues stroking.

While it's dark, you can tell her mouth is full, and she closes her lips and makes a show of drinking your semen down. She licks her lips and then attacks your cock again, cleaning you before standing up. "Was it good?" she asks.

You groan your approval and palm her breast while you kiss her. You aren't sure if you like the salty taste or not, but your girlfriend's wild tongue dances in your mouth so fiercely that you also realize you have more important priorities to take care of.

"Should we get to our room?" Jess asks, tugging at the bottom of her top, pulling it up to reveal her toned body. "Or is there more important business to take care of? Specifically, my slick pussy," she adds as her voice gets huskier.
