Fictional story and characters:
Raj finally settled their living arrangements with Leonard and after signing contract and participated on drills required by Sheldon, he fitted right in. He was glad Leonard came up with the idea to trade places while his sister Priya is in town. The constant fucking between his sister and Leonard, in his own bedroom, flooded his thoughts with images of his sister in various sex positions each time he heard them role-playing; Leonard with his Star Trek theme and Priya's references of Kamasutra sex positions. He hated to admit it but there were times when he watched porn that the girls in the scenes morphed into the image of his sister.
The living arrangements worked very well; Sheldon experienced the difference, as Raj said, between eating and dining especially with the touch of origami napkins. For Raj, he can do his nightly ritual of downloading and watching pornography in private. To top that, the images of the girls seemed to morph into Penny instead of Priya since he now constantly sees her in and out of the apartment.
Raj has been dreaming of having it with Penny since the very first time she was introduced to them with just a towel on. He couldn't forget and always in his thoughts how he had a bonner when she got really close and hugged him after she poured out her thoughts of Leonard and Sheldon when they invaded her apartment while she was sleeping. Her scent and her bosoms pressed against him lingered each time he sees her.
"Perhaps I'll have that chance..." Raj said, his thoughts wondered around Penny as he watched porn and wanked.
-------------------------
Penny joined Sheldon and Raj for a dining experience in their apartment and began chatting while they enjoyed each other talking and drinking wine.
"More wine?" Raj offered Penny.
"Oh, no, no, no. I've had way too much already," Penny said as she raised her glass and took a sip.
"Here's an interesting fact about alcohol," Sheldon said.
"Hit me," Penny interjected as she reached out with her glass at Raj.
Sheldon ignored Penny's gesture, "Man is not the only species that ferments fruit in order to become intoxicated. Can you guess what the other is? Hint, sometimes they pack the alcohol in their trunks," he continued.
"Monkeys," Penny answered.
"When does a monkey have a trunk?" Sheldon asked with his quirky attitude.
"When a suitcase just won't do," Penny answered as she laughed.
"Mmm, all right. It would appear as if alcohol is playing keep-away with your intelligence. Good night. Please note, it is now past ten p.m. Per our roommate agreement, kindly refrain from raucous laughter, clinking of glasses, and celebratory gunfire," Sheldon said as he sensed Penny's drunkenness.
Penny watched Sheldon walked to his bedroom. "Okay, explain something to me. You watch Leonard put up with that guy for years and years. What has to break inside your brain for you to think, Oh, Krishna, I've got to get me some of that?" she said to Raj.
"Well, it's a lot better than having to hear all that sex in my own apartment," Raj said with a disappointed tone.
"What? Oh, God, yeah. Yeah. Leonard's a noisy little dude in the sack," Penny commented as she remembered her sex with Leonard.
"Every night," Raj added surprisingly.
"Really? Even during allergy season, when he has to alternate between kissing and breathing?" Penny commented sarcastically.
"It's my sister. Can we not talk about this any more?" Raj said acting disgusted.
"Yeah. Sorry, sorry. Can I tell you a secret?" Penny apologized.
"Yeah," Raj said interestingly.
"I screwed up. Leonard's a great guy. Never should have broken up with him," Penny confessed sadly, regrettably.
"Well, uh, to paraphrase Shakespeare, It's better to have loved and lost than to stay home every night and download increasingly shameful pornography," Raj said for Penny to refocus her sadness to something else.
"Oh, you poor baby," Penny said apologetically but kept her thoughts of disgust to herself.
"What's wrong with me, Penny?" Raj asked feeling sorry to himself.
"Nothing, nothing. You know, if we weren't friends, and you hadn't brought up that creepy pornography story, I'd be on you like the speed of light squared on matter to make energy," Penny said trying to cheer Raj.
"Hey, you totally got that right! E equals M C squared," Raj said excitedly.
"I listen. I have no idea what it means, but I listen," Penny said proudly. "To friendship," she said and raised her glass.
"To friendship," Raj replied as they clink glasses.
"Would you booze hounds please stop that infernal clinking? And the answer was elephant!" Sheldon yelled from his bedroom.
Penny and Raj snickered at Sheldon's outburst. They continued the chit-chat as they consumed wine. As they both getting drunk and bolder, their topic started to drift to sex. Both were already under the influence of alcohol that they talked and exchanged thoughts that doesn't make sense, absurd or just plain nonsense and laughed at their words. But Penny's much, much drunker and Raj played along as he thought of a scheme to get in Penny's pants.
Penny suddenly felt some jealousy with the thoughts of Leonard and Priya together, "So you said every night?" She asked slurring.
"What?" Raj asked, his word much clearer than Penny's.
"Priya must be something," Penny added.
Raj nod his head slowly, agreeing, "Maybe you forgot that we invented sex right?" he said with pride.
"Oh yeah. Right... that book Kam... su... something right?" Penny dizzily said.
"My sister most likely showed Leonard some moooves," Raj said as he gestured a sex act with his hips then snickered.
Penny laughed at Raj's act, "Hmmm... you done it?" she asked giggling.
"Me? Shus... done it lot of times," Raj bragging.
"Reeaally? Lots of tiiimes? With whoo? Hmmm," Penny asked doubtfully with squinted eyes.
"Ah... Ah... with you... in my dreams when I jack-off to it," Raj stuttered and confessed with the words trailing to silence, embarrassed.
