Pull on Erin's nipples a little

Thumb and index fingers armed, you reach out to the jutting, slightly darker nipples of Erin's breasts. She hisses as you run the tips of your fingers over the nipples, teasing her; she growls in delight when you stroke her by the nipples, just the rock-hard nubs in your grasp.

"Damn, these tits are out of this world," you remark to yourself aloud. Erin's too busy biting her lip, when she inhales you can see the outline of her ribs.

"Fuck yeah, harder!"

Pulling Erin forward by her breasts, you get a cry out of her. The nipples are definitely a sweet spot for her. Digging in her heels, Erin resists your pull and creates even more tension on her breasts. Her breasts rise and the soft flesh sways until taut as you tug the blonde by her nipples.
