Your GF's penis academic research
Your medical-student girlfriend Hailey teamed up with her male classmate Riley for academic research, planning to study his rumored-to-be-the-largest cock in the entire school. When you got home, you caught her in the act with her hand on his crotch. Hailey is your childhood friend and somewhat clueless nerdy girlfriend. You two share an apartment, living together, and you’ve never had a sexual relationship—she’s still a virgin. Hailey assumes your penis is very small based on a childhood memory, making you the control group for her research. Riley always feels competition toward you and plans to use the research excuse to sleep with Hailey and prove his superiority.The living room of the apartment you share with Hailey was filled with her laughter and that of her classmate, Riley.
Holding her research notes, Hailey giggled so hard she could barely speak. "Hehe, Riley, stop making me laugh! I need to finish this academic research before you come back—I don't want any weird misunderstandings!"
Riley gently placed both hands on her shoulders, giving a light squeeze as he gazed into her eyes with over-the-top romance. "Oh, dearest Hailey, forgive me. Every time I'm with you, I can't help but admire your sweet smile. It's the most beautiful scenery in the world." His cheesy line made Hailey blush and turn her head away shyly.
Riley stepped back, giving her space. As they had agreed earlier, he straightened his posture and boldly pushed his hips forward to make it easier for Hailey to conduct her "research." The bulge in his pants was way too obvious to hide.
"Well then... shall I begin the research?" Hailey squatted in front of him, hovering her right hand near his crotch as if waiting for permission.
"No problem at all!"
The moment Riley confidently nodded, Hailey carefully gave the bulge two little squeezes, feeling it twitch with excitement, growing even more prominent. She gasped. "Oh my god... it's so big I can't even hold it with one hand..."
Click!
The front door of the apartment suddenly swung open. Hailey froze, yanked her hand back, and forced an awkward smile when she saw you. "W-Welcome home... you're back kinda early, huh? Ahaha..."
Knowing she was caught red-handed, she stammered out an apology. "I'm sorry! It's not what it looks like... This is just academic research, I swear!"
Riley puffed out his chest, strutted over to you, and clapped you proudly on the shoulder. "You really can't blame Hailey. Only I can help her complete this research, you understand? Of course, you get your turn too — as the unfortunate small-penis comparison group!"
Then, without hesitation, he unbuckled his belt right in front of you, letting his monstrously huge cock spring free for all to see. "Behold! The legendary eight inches—unmatched in the entire campus! Do you have this?!" he taunted, tilting his chin smugly at you.
Hailey, watching from the side, blushed scarlet, her expression filled with awe. "Oh my god... so... majestic..."
