Playing Uno... jk, you get it on.

You were about to answer her question, but Olivia throws herself in your arms, and you tip backwards over the arm of the couch. As you lie in a frankly uncomfortable position, you giggle and scans Olivia's face. She is absolutely beaming. It's not in her usual smug and sardonic way. For the first time, you see her truly and sincerely content. You see her troubles and doubts and lack of self-worth disintegrate like a therapeutic magic act. You see the small brown spots in her adorable green eyes overlap with your own... you know, like in that Postal Service song.

However, your back is breaking from this awkward position, and something hurts; you're not quite sure what, but you suspect it might be your colon, so you gently guide Olivia with you as you move further down the couch so you're not using Olivia's magnificent body to crush your legs, lower torso, and (presumably) your large intestine.

"So, I was thinking that we could get naked, and then make out, and we could explore each other." Olivia proposes in an uncharacteristically gentle and delicate way. "What do you think?"

This is it. The moment you have been waiting for ever since Olivia first spoke to you.

"Not gonna lie, that's kinda gay." you respond

YES! Finally! After all of this time, you finally have your revenge. This frustrating sentence of a snarky little brat (who you do still love dearly) has been burned into your mind for almost two weeks, and now you finally have your retribution. Oh boy, it feels great to be alive on such a momentous day. "Give me irony or give me death!" you think to yourself.

"Oh, fuck off." Olivia giggles as she playfully punches your shoulder.

"But yes, I would love that." you say. You are confident that your face is kingly crimson at this point.
"Then strip, girlfriend." Olivia smugly replies.

Olivia gets off you, and you sit up. You pull your t-shirt over your head reveling your bra, you quickly get your socks offs. You fumble with your jeans, and Olivia helps you pull them off. You are about to unhook your bra but Olivia speaks up.

"Uhmm... Can I do the rest?" she asks with downcast eyes.

"Of course, honey." you reply.

Olivia hugs your chest tightly, burrowing her face into your breasts. You are pretty sure she would be able to reach you bra clasp without having to throw herself in between your tits, and that she is just using it as an excuse to get a faceful, but you're not complaining. She unclasps your brassiere, and she lets unceremoniously fall to the floor. You can feel yourself getting really excited, as you prepare yourself for her to pull down your panties.

However, that doesn't happen.

Olivia buries herself in your breasts once again, motorboating the ever loving shit out of them. "Blblblblblblblbl" you hear from the face deeply latched to your bosom. You giggle a bit. You also moan a bit. A moggle, if you will.
Olivia isn't done yet. She detaches herself from your cleavage, only to sate herself on your nipples. She sucks and slurps your tits, alternating between the two. It's arousing. Really arousing. It's also pretty adorable the way she wants to worship your body. A pang of guilt enters your mind, but the sensations in your areolae quickly dampens it.
After a minute or two she is finally ready to move on. She gives you a quick kiss before she moves down to your lower body.

She grabs the sides of your panties, and as you slightly lift your butt in the air she pulls down your last remaining piece of clothing.

There you are, completely bare in front of the girl you love. Her inquisitive mind positively brimming with lewd curiosity. Endless possibilities, and a willing body for her to conduct her erotic experiments on. You almost get a bit scared of what she is about to do.
She opts for the safe route, however, and hurriedly submerse her face into your loins.
She is all over your vagina. She does it pretty haphazardly. It feels more like she is trying to please herself more than you, and you are pretty confident that if she just calmed down a bit, you would probably enjoy it a bit more, but you don't really want to ruin her fun. Plus her absolute devotion to please you, and use you, is more than enough to get you moaning, even if the pleasing in and of itself isn't that skilled. She has plenty of time to learn (and to be fair to her, you don't know squad about this either), and right now, you are more than content to just see her happy.
After a little while you do have your orgasm. You roll your eyes back as you buck your hips in pleasure, and your already wet private bits, gets drenched even more. Olivia laps up your juices, as if to reap the spoils of her war with the nefarious nether region.

As you lie in your post-climax daze you realize that Olivia is still fully clothed.

"It's a bit unfair that I'm lying here, and having an orgasm, and you are still there fully geared up." you say as you gaze lovingly and lovedrunk at Olivia.
Olivia just kind of fidgets in her seat.
"What's wrong?" you ask concerned.
Olivia tightens up even further and you can see clear shaking.
"Ollie... darling... speak to me." you plead.
"I'm not..." she starts but quickly stops again.
"If you aren't ready, then it's fine, we can wait." you respond.
"No, it's not that. I-I'm ready. More than I have ever been but..." she stammers: "I'm just not..."
"Is this about your body again?" you ask
"...yes." She admits.
"But I've already told you. I think you are beautiful. I think your body is stunning, and your face is so lovely I wish I could stare at it forever."
"I know." she says.
"You do believe me, right?"
"Of course I believe you, Astrid."
"Then why do you still hold yourself back?"
"I don't know."

Olivia is clearly uncomfortable in showing you her body, but she also seems to really want you at the same time. A painful dichotomy.

An idea springs to mind.

You softly grab the zipper of her hoodie, and you lead it down her body, loosening it.
"I want to prove to you how gorgeous I think you are." you say with a warm smile.
You slump the hoodie off of her shoulder and it falls down on the couch cushions. Olivia doesn't resist. She doesn't say anything either.
"When you were licking and kissing my body like a worshiping ritual I couldn't help but feel extremely flattered."
You carefully pull of her socks making sure that you don't overstep any boundaries.
"I want to show you that the feeling is mutual."
You slowly lift up her t-shirt. Olivia loosely lifts her arms up, helping you to take off her shirt.
"But for that to happen I need you to be naked."
You undo the button on her cargo pants, and pull down the zipper. Olivia rises up a bit, and you pull down her pants, now revealing her half-naked body.
"I just want to show you, how much I love you, Ollie."
You cup her melancholic face, and you massage her cheek. You lean in close and giver her a deep and long but tender kiss.
"Please let me show you, how much I love you."
Olivia doesn't react for a couple seconds. Then she slowly nods.

"I'm going to take off your lingerie. Is that okay with you, sweetie?"
She nods again.
You unclasp her bra, and pull down her panties, leaving her naked. You are now seeing Olivia's lovely naked body again. It's time to gently please her, and raise her spirits a bit.
You cup her breast.
"These breasts are absolutely perfect, Ollie." you say as you plant a kiss on her left nipple. "Just the right size to be absolutely gravity-defying. These breasts are going to be perky all the way to age 35. How you can't love them yourself is beyond me."
You start to gently suckle on her nipples. You are a lot less aggressive and fast than Ollie was, but you think she needs the gentle treatment. You softly pull on the nipple you aren't sucking, rolling and playing with it. You hear Ollie moaning. It's working. You alternate between her breasts gently sucking and licking her breasts, and playing with the one you aren't orally pleasuring.
"This stomach is absolutely perfect as well." you say as you finally let her breasts go. You look at her adorable love-handles. You plant a kiss right above her navel.
"And guess what Olivia. This whole area here..." you say as you circle your hand above her vagina to showcase what area you are talking about: "This area embodies the word "perfection"."
And then you go to work.

You gently pleasure her clitoris with your tongue. Up and down. You flick it like one of those old toggle light switches.
"Oh... yes... Asta... don't stop." Olivia moans as you work on her happy button.
You slowly move down to the slit. You stick your tongue inside her to the best of your ability. You tongue, taste, and sip her lovely tenderness. As you please your girlfriend, her moaning starts to get louder and louder.
In the corner of your vision you see her firmly grab the couch cushions, and that's when you know that she is going to climax.
As she her body spasms in release you, lick up all of her fluids, just like she did to you.
Olivia lies tired on the couch, breathing heavily. You move up to meet her face once again.
"You have a perfect face." you start again: "Perfect eyes. Perfect hair. Perfect lips. Perfect freckles. Perfect blushing cheeks. I love all of these things about you, but the thing I love the most..."
You move further up and kiss her forehead.
"...Is your perfect brain."

Olivia's face has returned to a smile. It seems a tad bit smug, but that's how you like it.
"Too cheesy?" you ask.
"Maybe a bit. I still loved it though."
You kiss again.

You cuddle on the couch for about an hour, before you get dressed and clean the couch. Vanessa will likely want to use that couch at some point, and the love potion you and Ollie have brewed on it would probably make it a bit icky.
