Explain yourself.

"Mmm," is all you can say.

The first catkin slides her hands over the fingers caressing her chest.

"Do you think it hurts him somehow?"

"We can test it and see," the newcomer says. She grins.

Coming back to her side, the black-haired girl takes the other's face in her hand. She slides her fingers down the soft skin of her cheek and moves to press her lips lovingly to the other's. She kisses her passionately. Then, her hands become adventurous and slide down to her hips, wrapping around to squeeze her rear end. In response, the blond-haired girl lets out a sharp moan.

"Really? Right in front of him?" the topless girl asks.

"Mhm... Why not?"

Now the other girl wraps her arms around her, but instead of wandering down, she moves to the back of her bra strap and begins to work it free. They kiss again, and it lingers for a long time as they begin to explore each other's mouths with a lustful passion. Her bra becomes discarded, leaving their bare tits to press together. Their nipples begin to grow excited, and their faces flush red with desire. Fully now, they start to slide their hands over each other's mostly exposed bodies while they make-out in front of you.

One kisses the other's neck, causing the first to raise her head--mouth agape and panting.

It's the blond-haired girl who slides her daring finger down the front of her friend's panties.
