Sheldon went to Penny's room and closed the door. Penny knocked and came in. She was shocked at what she saw: Sheldon was buck-naked on the bed kneeling down, opening a condom packet. His cock was erect and the biggest fattest one she'd ever seen. Easily 9 inches maybe even 10. Sheldon said in his nonchalant monotone: "I was wondering when you were gonna show up. Now come up here and lets get it on." Sheldon started chuckling in his usual awkward manner. It was rather incongruent considering that his member was standing up in full salute!

Penny took off her shorts to reveal her usual thong. It had Wonder Woman on it. Sheldon saw it and his cock got even harder. Penny backed up on the bed for Sheldon to fuck her doggystyle. Sheldon moved Penny's thong to one side and started licking her pussy. Penny MOANED. "FUCK Sheldon you have the longest tongue ever what the fuck is wrong with you?"

Sheldon stopped. "I'm sorry Penny I dont understand."

"Why have you been hiding this?"

"I haven't been hiding it I've always been right here" Sheldon said, as he had a perplexed look on his face.

Sheldon continued to jam his tongue into Penny's sweet shaved pussy. He loved her pink lips and how she tanned nude so the bikini area had no tan lines: just beautiful tanned skin.

"FUCK me Sheldon. Stick that big alien cock in there."

"Alien?" Sheldon looked perplexed again. "I'm not an alien!"

"Whatever Sheldon just fuck me with your cock."

"I intend to" and with that he pushed it in her while holding onto Penny's ass.

"Aaaaaaaaahhhheeeeeeeeeefuckkkkkkkkk" Penny said as Sheldon pushed in the biggest cock she'd ever had! And Penny had had a lot, having slept wtih well over 20 men in her lifetime.
