It's just too much for her

As you return the girl's attention to your cock with a tug on her hair, she moves onto all fours to let her blue-streaked friend (wait... Did she just say 'cousin?') crawl around behind her. She looks up at you over the back of the other girl while letting one hand slip down.

You smile back and begin to pump your hips, still holding onto the pink-streaked ponytail. It doesn't take long for you to get balls deep; clearly she's used to this kind of treatment. It starts to get a bit sloppy but you continue anyway, finding a nice comfortable pace as you fuck her face.

Blue dips her head, beginning to lick at her friend's crotch. The reaction is immediate: you feel her moan around your cock, and her blowjob gets even messier. This won't do at all... Pulling her mouth off of your shaft, you reach down and squeeze both of her nipples through the metallic-pink bikini top.

"Eeee!" she squeals. "So goood! Keep playing with my nipples, she's got me close to- mmf!" You silence her by returning your cock to her mouth. For a little while you struggle to get a good angle - her breasts are big enough that it's hard to reach around to them with her head buried in your crotch.

Frustrated, you stop the blowjob yet again and stand up, stripping off your clothing; getting a blowjob over the top of your jeans is great, but you don't want them getting in the way once you start fucking.

Once you're naked you crouch back down and seize hold of her nipples. Her noises of pleasure grow louder, and several of the other picnic-goers look over. You ignore them and watch her face as she shudders through another orgasm, her eyes rolling back and her chest heaving with excited gasps.

Once her climax finally passes she goes limp, falling face-down on the picnic blanket. You brush her hair out of her face, and are a little surprised to see that she's totally ****... Though she still has a big smile on her face. Her cousin sits up, leans over, and licks some of the spit and pre-cum off of her face.

Looking back over to you, she feigns an apologetic look. "So... Did I overdo that?" she giggles. "I guess that means you'll have to use me instead, right?"
