What is happening to me?
"Wh—" Michael was about to ask her what happened, but he stopped when he heard her crying.
"T-Thank g-goodness, y-you're okay! I-I was so fucking worried about you. I-I c-couldn't focus on my research u-until Mom texted me that you were okay! T-There was so much b-blood!" Theresa exclaimed, sobbing and crying while tightly hugging her little brother, trying to contain the emotions flowing through her.
"There! There!" Michael hugged her back.
"Why are you still crying?" He asked teasingly with a smile when he saw she hadn't stopped crying.
Theresa kept hugging him tightly and said, "I-I am not crying! T-These are tears of joy! I-I am happy that nothing serious happened to you!"
Michael's smile, however, froze when his cock was slowly hardening. He widened his eyes and thought, 'No, no, no! Why now? Why he—'
Theresa hugged him even more, and only then he realized that her big boobs were squashed against his chest. He could feel her nipples poking his chest through the clothes, and it didn't help with the erection that was slowly rising.
He thought, 'What the fuck is wrong with me? Why am I getting aroused by my older sister? It must be the drug affecting me. That's why it's not letting my cock die down. Fuck!'
'If this keeps up, Theresa will find out. She will be very disappointed in me and never look at me the same way. I don't want that, especially with the older sister who loves me!' Michael cursed himself.
He was trying hard not to panic and ruin the moment when an idea popped up in his mind.
'She is my older sister. I've known her my whole life. So, it's natural for her to worry about me. As soon as she knows everything is alright, her mood will calm down, and she will leave. All I have to do is to keep hugging her and wait until it calms down. At least it will make her feel better and leave with a smile. He sighed in relief and hoped.
After five minutes, Theresa calmed down and said, "Sorry. I... was scared and wasn't focusing on work, so when Mom sent me a text that said that you were okay. I was relieved, and for the first time since this morning, I could focus on my research work."
"It's okay. Everyone is allowed to have a breakdown once in a while. It's a good thing you had yours sooner and not later. I can't even imagine if it was later.", Michael assured and smiled, and the two looked at each other and laughed.
"That was a lie. But, thanks for being here for me." Theresa hugged him again.
'Great! I didn't think it would work! Now, can you let go? You'll find out in a minute, and I'll get destroyed by embarrassment and disappointment.' He thought, anxious to break the hug.
Finally, Theresa released the hug, smiled, and kissed him on the cheek, saying, "It's good to know that you're fine, little bro."
"Yeah... sure. You too." Michael nodded, and he quickly bent down to pick up her research stuff and used it to hide his semi-boner.
"There's no need to do that!" Theresa said and tried to grab her research stuff from him, but he kept dodging her and headed towards her room.
"No, no, no! I insist!" He said without turning back and jogged upstairs with a big smile.
"Oh! Alright, then. Thanks, Michael. Thanks a lot!" She replied and went into the living room.
"You're welcome, Sis!" He yelled from upstairs, not daring to meet her face for now.
He stopped in front of her bedroom door and looked at his softening cock, and said in his head, 'That was the most awkward moment I have ever had. Let's hope that there is no next time.'
He nodded, opened the door to Theresa's room, put her research stuff on the table, and walked out. Closing the door behind him, he walked downstairs and entered the living room, where he saw Theresa sitting on the couch, surfing the channels on TV.
He walked over to her and plopped down next to her, and they began talking while surfing the shows.
Theresa said, "I'm going to take a shower. I've had a long day, and I feel kinda tired. Today's work was difficult and tiring, but it ultimately paid off."
"Okay." Michael nodded and then realized that she was waiting for him.
He said, "Okay?"
Theresa nodded, got up, headed upstairs to the bathroom, and went inside while Michael watched the shows. Sometime later, he heard Theresa entering the living room again.
He kept watching the show and said, "Hey, Theresa. You're done with the shower?"
"Umm... Duh?! I've been in the shower for a while, y'know." She retorted, causing him to turn his head and retort back, but...
He swallowed his words when he saw her.
Theresa was wearing a white, low-cut tank top, revealing a delicious amount of cleavage, which, along with her bra, was showing half of her big breasts. Her frizzy, blonde hair was wet because of the shower, and water was still dripping down her hair to her neck and her exposed cleavage, making her tank top cling to her skin.
He felt his cock beginning to harden again, and he quickly looked back at the TV while thinking to himself, 'Fuck! What the fuck is wrong with my body? I didn't get turned on this easily before, and definitely not by my own fucking older sister!!! This is getting worse. What the hell is this? It's like my body doesn't care if it's my sister. If it's a girl, it just turns on like a light switch! What the fuck is in that drug?! What the fuck is this shit!?'
Michael took deep breaths and focused on the TV while Theresa sat on the couch beside him.
Thankfully, she switched to the news channel, and they began watching the latest headlines and breaking news, which helped him take his mind off certain things.
Theresa asked, "So, how many days are you going to rest?"
"The doctor said one week.", Michael replied.
"One week?" Theresa turned to him sternly and said, "Then, you must study at least 2-3 hours daily! I don't want you to fall behind. You have to make up for the missed classes so that, when you return, you won't fail in a surprise pop quiz."
Michael didn't reply and groaned instead. He wanted to relax and have fun. He wanted to spend the time on something other than studying and reading books.
Theresa made him turn to her, and she said with a severe tone, "Promise that you'll study at least two hours a day for the next week."
Seeing her solemn look, Michael replied, "I'll try."
"What do you mean, 'I'll try'? Either you will do it, or I'll tell Mom and..." She threatened.
"Okay, okay. I promise! I'll try to study two hours a day!" Michael relented in fear.
"Good." Theresa smiled, and they turned back to the TV.
Suddenly, a loud ding from the microwave in the kitchen was heard, and a smile formed on Theresa's face as she said, "Oh! That's my dinner!"
Michael nodded and asked, "Would you like me to take it from the microwave and bring it over here?"
"No, I'll do it," She said, getting up from the couch.
But, as she got up, the shorts stuck to her ass, and her booty was sticking out more than usual. Michael glanced at her booty, and his cock couldn't resist and instantly became erect. He thought, 'Fucck! Why now?! Fuck! Now, I have to go and jerk off quickly, or else my cock wouldn't work.'
"I'm going to the washroom!" He shouted and bolted upstairs.
