Keep up the , make her cum

You try to make her orgasm, deciding you want to see this beautiful blonde cum on your fingers. You start ripping your fingers in and out of her maniacally, with as much for as you can must.

Erin's wet... but she doesn't cum.

You really double down: focusing, you push up into her with your hand and finger her aggressively for several minutes... but, Erin isn't cumming... and your damn fingers are starting to get tired.

"If you're trying to make me cum, it'll take more than just your fingers," Erin offers scornfully.

Unsuccessful, you extract your hand; Erin's dripping less than she was a few minutes ago. Well, it was a nice gesture on your part, right?
