A friend's party

You had remembered that a friend was having a party on the weekend. You had decided to simply wish to be there --- where better to enjoy a dream about being able to grope any woman you knew? --- and you found yourself on their doorstep, music clearly audible from inside. Sweet!

You try the doorknob, and it opens. By coincidence, your friend Will happens to be right there. "John!" he says with a smile. "Glad you're here."

He pulls you in for a hug for a half-second, just long enough to be friendly. Just as you part, you hear a feminine chirp. "John!"

You look over to see Lara, Will's long-standing girlfriend. She's a bit different than you remember, though: in place of her modest B-cups, she is now sporting firm DDs which stand out from her chest, with significant cleavage with her green scoop-neck shirt. Her nipples form two prominent peaks in her shirt as she rushes towards you.

Lara rushes to bump into you, and you hug her more by reflex than anything else. You'd swear that she is deliberately pushing her chest at you as she hugs you back. You feel her nipples poke into you, and her breath catches. "Squishy squishy!" she giggles, pulling herself back. She shivers theatrically as if cold, and not-very-subtly jostles her tits for you to see. "Nice to see you again!"

You feel mortified and look to Will apologetically, but he simply looks on with amused fondness, chuckling. "Lara's been looking forward to you visiting all day, you'd better give her chest a good grope for the moment."

You tentatively reach out, with Lara watching your hand. You gently grasp some boob flesh. It feels slightly firm, and she lets out a ragged sigh.

You feel like you're in heaven, but you can't shake the feeling that any moment it will come crashing down on you, so you let go after about ten seconds. "John, you tease," she moans as you let go. "Okay, I'll let you off for now, but I want you to take proper care of me later on tonight. Have fun!" she says, bouncing off into the party.

You turn to Will. "It doesn't bother you if I feel up Lara?"

Will laughs. "I've seen you do a lot worse than feel her up! It's all in good fun, though."

... Huh. It looks like this is all for real --- and Lara's larger bust size also seemed to confirm it. The question is. what do you do next?
