The girl with long black hair.

"How about you?" You say, pointing to the girl with long black hair. She's been sitting there with a playful smile on her face, seemingly amused at the whole situation. Her smile only gets better when you call on her.

"Samantha?" Diana says, "what do you say? Want to help Joe get hard?"

"Sure," the girl responds, pulling her hair back to reveal a perfect, long neck, "What shall I do?"

"This is your experiment," Diana responds, "Men tend to be more turned on by visual stimuli than women, but it's up to you to discover what gets him hardest."

"I can do that!" Samantha says, standing up smoothly from her chair and walking over to get close to you. As she walks, she smoothly and swiftly starts unbuttoning her cream-colored top. In moments her shirt blooms open, revealing a smooth, perfect stomach above her blue skirt, and underneath her black bra surprisingly full breasts compliment her slim figure.

The shirt falls to the floor in instants. She stands in front of you, just a few feet away, letting your eyes room along her curves. Your dick is pointing right at her, about halfway to fully hard. She looks down at it, nods thoughtfully, then smiles back at you again.

Locking at eyes with you, she reaches behind her back and swiftly unclasps her bra. It falls to the floor, revealing her luscious, firm breasts, nipples surprisingly dark and deeply alluring. You feel hypnotized, and your cock starts to harden. She notices, and steps closer to you.

Now she's just a foot or two away, her smile is smaller now, as she's more focused. Your eyes can't decide if they should look at her amazing breasts, her beautiful face, or the perfect line of her flesh where her stomach meet her skirt.

She sees you looking down, and without hesitation, she loosens her skirt and it falls to the floor. She's wearing nothing but thin, navy blue panties. You're almost fully hard now, and she's so close you could grab her. You want to. Your eyes are roaming all over her body, hungrily.

Like she read your mind, she reaches out, grabs your hand, and presses it to her ass. You squeeze. She smiles big, grabs your other hand, and places it on her breast. It fills your hand satisfyingly, and you lovingly let your thumb slide across her nipple. Without thinking, you pull her body against yours, pressing your rock hard cock against her crotch.

She gasps, mouth open, still smiling, waiting to see what you'll do next.
