Senior Slump Part 5: Checking In

Part 4 (https://www.reddit.com/r/BallbustingStories/comments/18y4l3h/senior_slump_part_4_lacys_confession/)

When Sam arrived home that day, he immediately went to his room and collapsed on his bed. He and Lacy had talked after she stopped crying. He had told her he forgave her, that he understood. But the truth was he wasn't at all sure how he felt about her. On the one hand, she was a beautiful girl, popular, seemingly kind enough, and she was apparently very into him. On the other hand, though, she still had been his bully for many years, and though she had been very apologetic, he wasn't sure he could just forget all of that. But he had kissed her, though, hadn't he? Why had he done that? He still wasn't sure. He was even less sure where the two of them stood now. What were they? Friends? Were they dating now? That was something they had not discussed, and so for the moment, he was left with only questions.

He pulled out his phone and stared at the new contact, considering texting her. The picture she had sent him for her contact was charming - her in her blue, cotton pajamas, smiling and throwing a peace sign. Lacy Lang... Could they be the enemies to lovers story of Sunnyside High? He chuckled to himself at the thought. Maybe he could forgive her. She was very sexy. He locked his phone, closing his eyes and leaned his head back, imaging her on top of him, kissing him, undressing him, undressing herself. His hand slowly snaked its way down into his shorts. Lacy Lang, his girlfriend? She was very sexy. Very sexy.

Sam jolted and whipped his hand out of his pants at a sudden knock at his door.

"Sam?" came the familiar voice of his sister.

"What?" he replied, slightly annoyed.

"Uh, can I come in?" she sounded nervous.

"Why? What do you want, Penny?"

"I just- Look, can I just come in, please? I just want to talk."

He sighed. He wasn't sure how many more 'just want to talk's he could take that day, but in spite of himself, he got up and opened the door.

"What is it?" he asked.

She pushed her way past him and sat down in his desk chair.

He sighed again and shut the door, then sat back on his bed.

"Well?" he asked.

"You don't have to be rude, you know?" she teased, mock pouting

"Oh my god, Penny, can you just tell me what you want? It's been a long day, and my fucking balls hurt."

Penny dropped her act, looking slightly guilty at the mention of his balls.

"Sorry, yeah. Uh, that's actually why I'm here. I just, ya know, wanted to check on them- on you! Check on you, and stuff, I guess. Yeah. Oh, and I uh, brought you some ice, if that would help?" her face lit up like a christmas tree and she held out an ice pack.

He took the pack, giving her a suspicious look. It was most unlike her to do nice things for him.

"Uh, thanks." he said, putting the ice on his aching balls.

Penny stared at his crotch for a second, biting her lip, then spoke.

"Don't- Don't you think it was be more effective if you, uh, took- took off your shorts." she was staunchly avoiding eye contact now, and her face was beet red.

Sam stared at her, a small smile beginning to form around his lips. This little pervert wanted to see his junk again. He couldn't believe it. Suddenly all those strange looks she had been giving him made sense. His sister was a dirty little closet slut. The shear hypocrisy of it astounded him. But fine, if she wanted to play this game, then so be it.

"Oh, you're right, Penny," he said, "Let me just-"

And without further warning, he pulled down both his shorts and his boxers. Penny gave a quiet help of surprise as his still semi hard cock was revealed to her again.

"Ahh." said Sam, placing the ice pack on his swollen balls. He looked at his sister. She was staring hard as his cock, still biting her lip, her legs pressed tightly together. After a few moments of letting her take in his package, he decided to bring her back down to earth.

"You know, Penny. I just thought of something."

"Huh?" she said, almost like she was surprised he was still in the room.

"It occured to me that you've seen me naked quite a bit today, but I haven't seen you naked. Doesn't quite seem fair, does it?"

"W-what?!" she gulped. Now she met his eye, and in that moment, he knew he had her, "What- I- Oh, uh, n-no? I guess- y-you, you want to see me naked?"

"Well, it's only fair. You watched me cum like three times today, after all."

Penny gulped again, "Y-yeah, that's true. I did. I guess it is only fair, right? I mean, you're cock..." she trailed off, staring at his cock again. She sat for a second, and then said in a lusty whisper, "It's only fair."

With that, she stood up and pulled down her jeans, kicking them into a corner. Sam could clearly see a dark, wet stain on the front of her white panties. His dick grew harder. Unsure of where to look, she kept her gaze cast down as she then pulled off his t-shirt. She paused for a moment, then, psyching herself up, and eyes closed, unclasped her bra. Her breasts weren't large. Like Lacy, she had a slender frame, and her bust reflected this. Small, perky, and with nipples as hard as diamond, her tits jiggled slightly as she dropped her bra to the floor. Now, it was time for the final garment. She took a deep breath, took another long look at Sam's now hard cock, and then pulled her wet panties all the way to the floor. Sam couldn't help himself now, and slowly started to stroke his cock. Her pussy was drenched, the deep red lips swollen, pulling her cunt open as it dripped with lust.

"Fuck, Pen." Sam gasped

Without saying a word, Penny came to sit on the bed next to him.

"C-can I touch it?" she asked quietly, now maintaining eye contact.

"Yeah."

Slowly, she reached out and wrapped her slender fingers around his cock.


"Fuck.."

"God, your dick is so fucking big, bro. I can barely wrap my hand around it."

"Shit, Pen, you're gonna make me cum if you say stuff like that."

"Yeah? You gonna cum for your little sister?" she whispered in his ear, nibbling on it slightly, "Then you should make her cum, too."

With newfound confidence, she took his hand and placed it between her legs. Understanding her intention, he began to rub her pussy, following her pace. She moaned into his ear and leaned against him, her breasts pressing into his side.

"I've wanted to do this for so long." she whispered, stroking his cock faster, "You're so fucking hot, bro."

Sam followed her que and stuck two fingers inside her.

"Me too." he gasped, "So are you."

Suddenly, Sam felt her pussy constrict, and she moaned in pleasure as she squirted all over his floor. This sent him over the edge.

"Fuck!" he moaned as well, and came all over his sister's hand and chest.

"Fuuuck yeah." she gasped in pleasure, licking the cum from her hand.

They sat there for several minutes, panting, leaning against each other, knowing they had just crossed a line that could never be uncrossed.
