On her tits

You reach out and grab another handful of boob and say "I wanna cum all over these!"

"Mmm, ok," she replies, "just let me know when you're ready!"

You quickly give her a few more good pounds, slap her ass a few times, and say "I'm ready!"

You pull out and start stroking it slowly while she turns around and kneels in front of you. She grabs her tits in her hands and pushes them together creating a nice landing spot for your jizz. Even though they aren't the biggest breasts out there, they're still sexy and cleavage turns you on so much that the sight of her squeezing them together starts to put you over the edge.

As you near the finish line, you slow down a bit and bend your knees slightly to get a better aim on your target. You reach down with your other hand and pinch her nipple. She grins at you and moans, "You like that huh? You like these titties?" She shakes her breasts up and down at you and eggs you on, "Come on, cum on me. Cover my tits with your cum!"
