Approach the tall girl

You see the tall girl mutter to the boy (her boyfriend, presumably) beside her. He glances guiltily to her, back to Vivian, and then averts his eyes. You find this interesting. "Excuse me for a bit Vivian," you say, "I want to ask someone something."

Vivian smirks. "You always did like to tease," she says, squeezing her breasts between her arms. "I assume you want me to keep my tits out? Just put my bra with the coats," she says.

"Sure," you say, noticing Vivian's bra still draped over your arm. You're close to the coat rack, so you just hang her bra there by what looks like her coat.

You're interested by the reaction of the tall girl, and you soon find her and her boyfriend, who wandered towards the kitchen. They don't notice you and are having a hushed, tense conversation.

"I just want to feel appreciated," she says.

"I do appreciate you," he responds.

"Excuse me," you decide to interject before things get too awkward. The pair both jump slightly. The boy looks a little embarrassed, but the girl quickly recovers and looks a little annoyed.

"We're having a private conversation," she says, a little annoyed.

"In the kitchen," you point out. "I just wanted to apologise if I upset you somehow by exposing my friend's tits," you continue, fishing for her reaction.

The girl's face relaxes slightly, but does not brighten. "You don't have anything to apologise for. I think your friend's tits are great, and my boyfriend seems to agree," she says.

"Dawn, this isn't fair," Dawn's boyfriend complains. You realise that you seem to have inadvertently set up this poor guy for an argument with his girlfriend --- Dawn --- when you exposed Vivian's chest to the party. However normal it is for girls to occasionally be topless, when they were playing with one another, it seems to trigger Dawn to see her boyfriend looking at larger girl's chests.

"Sorry Dawn," you say, "I'm John, by the way," you add, "can I interrupt to ask you to take your jumper off?"

"Oh," says Dawn. She pauses a moment, as though someone were offering her a free ticket to a concert. "Uh, don't you mean that you'd like to take my jumper off?" she asks.

"Right, sorry," you say. You move in, and Dawn raises her arms so that you can pull her jumper over her head. She leans forward so that you can pull her top off of her long, tall frame.

Soon you have her jumper in your hands, and Dawn is standing in front of you in jeans and a black bra which contrasts sharply with her pale skin. Dawn's boyfriend is looking at you with something like pleased surprise. You extend her jumper to him.

"Sorry, er," you prompt him.

"Oh, Jim," he says. "Nice to meet you. Let me take that for you," he says, collecting Dawn's jumper.

Dawn is blushing slightly. "Is that all you wanted?" she asks, her voice less stern now, but thick with anticipation.

"I think I'll take the bra next," you tell her, moving in to reach around her. Her soft breasts are warm against your upper chest as you undo her clasp, and as you pull away they sag slightly downwards into natural tear-drop shape. You hand the bra to Jim, who is staring at Dawn's naked chest.

Dawn is blushing brightly, but smiling. "You don't have to do this," she says, "there are lots of bigger girls around."

You shake your head. "Your boobs are perfectly nice," you tell her, as you grasp one gently. Dawn giggles as her nipples come to attention.

Dawn's breast is firm, but less firm than either Vivian's or Lara's. "Do you mind if I ask why you didn't get a boob job, like most girls?"

Dawn's expression becomes more neutral. "I'm allergic to the standard augmentation agent," she said slightly breathily, "and the doctors determined that I had enough breast size and sensitivity that it wouldn't adversely affect my quality of life." She is starting to pant slightly. She looks over to Jim and smiles. "This is nice!" she says, leaning forward slightly so that you don't have to reach as high.

Jim smiles back. "I know I enjoy playing with your tits when I get the chance," he says.

Dawn looks at Jim with a sort of playful shock. "Jim! Not in front of our new friend! Oooh," she moans as you roll a nipple.

You're quite pleased by how you've managed to turn this whole scene around, but you're about ready for something more.
