Third base means any physical touching below the waist. (First base: kissing. Second base: touches above the waist.)

WARNING: this mentions partners NOT being ready in intimate situations and having to indicate a stop. It all ends good but if you cannot handle it then it is best you skip this one.

Daniel:

You were sleeping over so a lot of cuddles once the night came. Today was different than usual. Not something bad, just different. So you both followed it as both seemed okay with it. The kisses turned to touching each other slowly and anxiously, seeing what each other likes and dislikes, exploring: learning. Nothing was wrong, but just that alone already felt like enough for you.

"Can I..?" he asked as his hand stopped on your pelvis, eyes anxiously studying your expression.

"I think we did enough today already."

"Okay," he nod, pulling his hand off so both laid there, facing each other, smiling like idiots because you two are: two idiots in love.

"Thank you for trusting me, and letting me touch you," he whispered, feeling embarrassed to say something like that but knowing it can mean a lot to others. His embarrassment changed to feeling glad he did when you gave a kiss and told him you'll always trust him.

Zack:

He has always been a guy who moves fast, and now was the same. He pulled your clothes off so fast, so eager. He's so excited he felt sick, but somehow in a good way. He's gonna get laid! What boy doesn't like that?!

Oor not, because you kicked his stomach so he fell on his ass, asking, "What the fuck was that?!"

"What the fuck is with you?! Never heard of foreplay and setting mood?"

So it turned to an argument, him arguing he's just excited and wants to do it with you and you arguing back that's not how he should do it. It was back and forth until silence fell. Silence that allowed him to finally process it then groan and rub his face before dropping his hands, admitting; "It was wrong of me. Sorry... I won't do it again, next time. If you want to leave I get it..." Now that his annoyance vanished shame came.

"I won't leave. Just don't do it again."

"Okay. I promise." He felt glad you are staying but still ashamed. He can't believe he ruined it that bad then dared argue. He apologized for it a few more times later on in the week.

Jay:

Both laid down, holding each other, when you felt something. His face was bright red, sitting up on his knees and bowing his head. But you slid your hand on his knee, assuring that it's okay. Leaned up and captured his lips so he leaned back down, laying back down with you. Both held each other again, kissing. Slowly he moved his hips to yours. It was nice, and you didn't mind, but when his hand moved to undo your pants, only halting to look at your eyes for permission, you realized it might still be too soon.

His gaze held yours, so you told him, "I rather not."

He gave a firm nod and took his hand off then hugged you back close. But it's awkward to cuddle when he has that issue, and he must have sensed because he got out the cuddle, stuck up a finger as "wait a minute" then hurried away.

It was not a few minutes but eventually he returned, issue gone. He cuddled back to you.

Vasco:

It was fine, he asked "can I?" many times so you felt safe and not like an object, until you caught on to how nervous he is and began doing odd things so it made you nervous and unsure. He began good but then his touches became too hurried and rough so you had to pull your legs away and tell him, "Stop".

He immediately did. As if you stopped time and now he's frozen. Only thing that changed was his nervous eyes to one of genuine worry and guilty, asking; "Did I mess up already?"

So you told him not really, which made him confused so you had to try and explain of how his behaviour is turning you off. This made him awkwardly laugh, embarrassed as he thought he did a good job hiding it, then apologized before admitting that "maybe it's best we wait a bit more... Can we cuddle?"

So it ended up in a cuddle; which is okay, will both try again another time.

Jace:

He did so much damn research on this stuff to make it so you would have the greatest time! So to get halted halfway with a displeased look broke him. He was quick to ask what he did wrong, so sure he's following all that was written down and he prepared.

You told him: "You are moving as if this is a play, not with the flow and mood" he couldn't fault you. Sheepishly he agreed, then felt he should share more so he admitted he had it all prepared from sites he read. So both managed to fix this situation by reading the list he has, laughing at the sillyness but cuteness of trying to be that prepared, and you informing him of which parts you would rather not have done to you or he should focus on, and then the same for what he hopes you'll do and won't do.

Johan:

His hands roam your body as you laid with your back to his chest, both watching TV. It was a boring show so the excitement of his hands roaming was welcome. They mainly roamed your upper body. It started as a massage and somehow became this. You felt the issue in his pants against you so became unsure if you should roll back to it or just stay still. He gave your cheek then neck some kisses, asking if he can continue.

You took too long to answer, so he said, "Don't have to."

"No, just-"

"Took too long," he dismissed, moving his hands to slide around you so he was hugging you. "It's fine."

"But-"

"If you aren't hundred procent sure then I don't want to do it."

So he just held you. You asked what about his issue, to which he stayed silent, so long it turned awkward, then mumbled it'll go away, eventually.

Jake:

You both returned from an evening of hanging out. He might have drank a bit, leaning in to whisper to tell no one. So you laughed you won't. Once the door was open and inside he twirled you to give you a deep kiss, moving to pin you to the wall. Your hands slid in his hair, returning the kiss. His hands slid around your waist to hug you close to his body, just loving you so much he wishes he can show it but he won't ever be able to say or show how much it is.

His hands moved from your chest to your waist, trying to tug your clothes off. Your mind went alert as you two had done this plenty but never gotten further than the waist level. So his hands now there, one moving to rub between your legs, you crossed them. He stared at it, trying to process then looked at you with nothing but desire behind his eyes.

"I can't continue."

"That's the point."

"... You don't want me to?"

"I don't."

He stayed silent then stood up straight, and SMACK! He slapped himself!

"Why did you-?!"

But he already moved away. He locked himself up in the bathroom. After a while he got out of it, refreshed and back to his usual self; asking what you want to do now.

Gun:

He had plenty of intimate partners already, so for him to read your body language during this was simple. He saw you were uneasy, but he kept going, deciding if you really don't want it will say so and you probably getting over the mental hurdle. His movements were slow, so you could be sure.

You became sure. You are not ready and want this to stop. So you grabbed his wrists. You began saying; "I don't want this" but he was already pulling away, answering casually with a shrug; "I saw, it's fine". He just flopped aside you, pulled you close for a snuggle, and went on his phone to show you some video he had saved on it earlier he saw he knew you would like.

Goo:

It was fun, both being silly. The quick small pecks he gave in the cuddle turned to longer kisses and soon it was a make out session. He moved to lay between your legs, grinding his hips down to yours. You both have gone from first base to second already, so the kisses and upper touches was nothing new, but the hip grinds were. And he seemed eager to go further than just grinding. It caused an immediate panic in your chest, clenching so tight that your hands flew to push on his pelvis and say: "Stop!"

"What the fuck?" was all he said, surprised at the sudden change. "What?"

"I don't want it."

He watched your hands start to shake, your eyes blink more, swallowing deep. As if scared he will say 'don't care' and continue. So gently he cupped a hand to your cheek, thumb stroking your cheekbone, then gave a tender kiss, "Kissing good?"

To know your boyfriend was okay with it, to get that assurance, caused the panic to ease away. "Kisses are okay."

So both spend a bit of more time just sharing soft, gentle kisses before going to play a game together.

Taesoo:

You were both watching a movie, the mood was right and you didn't mind his hand rubbing your thigh. His hand slid to the inner side, giving it a squeeze. He waited, eyes on the TV but still waiting to see your reaction. You didn't swat him off or shift so he slid his hand up, moving his head to give your cheek a kiss. You were enjoying it but it felt wrong. So your hand went on his, "I'm not ready."

His hand stopped, eyes staring at your face for a second or two then he nod.

"I can't put it into words but-"

"You don't have to," he interrupted, moving his hand from your thigh to wrap it around your shoulders and pull you to his side to cuddle, "If it doesn't feel right then that's enough. Plenty of time."

Out of curiousity also asked: "What if I never want to do it?"

"Well, I have a hand, don't I?"

Jichang:

The mood was right but the setting wasn't. It was at his desk, both were being more touchy than usual. Soon you found yourself standing between his legs, kissing, his hands sliding over your legs then gripping the back of your thighs to pull you even closer. His kisses moved from your lips to your neck. His hands slid upwards.

It was perfect. Had it been somewhere else. You wanted this, but something in you was twisting. You knew you wouldn't be happy if this is where it would be. When he felt your hand push his shoulder, even just the light push, he looked at you, halting his hands.

"What?"

"It's..." it felt foolish to say, telling yourself it can still happen here, "Nothi-"

"It's something. What?" He leaned back in his chair, moving his hands. Not off you, just to take your hands in a soft hold, a reassuring manner to tell him anything.

"It doesn't feel right to do it here."

At that he nod. He gave your hand a kiss, "Thank you for telling me. I'm sorry for not considering it."

You assured him it's not his fault. He pulled you on his lap, asking if you thought he would have been angry. Both ended up just talking, halting the intimacy for when the setting is right.

Seongji:

He didn't know what to do but he went off what felt right. But sometimes that doesn't mean it feels right for the other person. So when he saw your body twist away from his touch he stopped, staring, as if to make sure. His mind didn't think it was due to displeasure but because his hands disgusted you as it must feel odd so he took his hands off, mumbling, "sorry".

So you told him, "It's okay, just... can we stop it here?"

"Okay..." He sat away, a distance between now instead of priors closeness. He did not use his hands again that day, which felt awkward. Until he had to. You asked him to get a dessert so he gave it, but flinched when your hands touched. Of course you asked, "What was that for?"

Anxiously he replied; "You don't want to feel my hands..."

"What..?"

"You didn't like it when we-"

"I meant the action! Not your hands!"

Hearing you answer that quick and defensive, as if it insulted you, made him feel warm and treasured. A smile even formed from it. But then a bright blush when you added,

"Better yet: I want your hands all over me!"

Then he laughed, a pure laugh of joy, playfully answering: "I might if you don't stop it."

I figured this was a good chapter as these are young men and it is normal for young people to begin exploring these things.

ALWAYS be safe, ALWAYS have a safe word, ALWAYS communicate with your partner even if it feels embarrassing.
