Of course, it wouldn't be the first time

"I've seen your cock before," she reminded him with a nervous chuckle. "Remember that class trip? I caught you jerking off in the woods on our day off."

Seth chuckled at the memory before agreeing. "Okay. But just for a quick look."

As he pulled back the blanket covering him, Eden's eyes widened at the sight of his bulging pants. She couldn't believe how big he had gotten.

"Jesus. I don't remember it being that big." Eden exclaimed, her eyes fixed on his crotch as he unzipped his pants and freed his massive erection.

"So big...and clearly affected by the serum." She observed, inching closer despite her inner turmoil.

"Can I...get closer?" She asked tentatively, knowing deep down that she wanted to touch him.

"Please, do." Seth replied eagerly, his own desires getting the best of him.

As Eden got closer, she could feel her arousal building even more. She couldn't believe how attracted she was to her friend in this transformed state.

"Well, other than the size, it doesn't look any different." She commented, trying to focus on the scientific aspect of their interaction.

Seth nodded in agreement, but his eyes were fixated on her hand as it reached out and softly touched his enlarged scrotum.

"Your balls are certainly bigger too...where did they do the injection?" Eden asked, unable to resist exploring further.

"Right around here." Seth pointed to a spot on his sack.

Eden brought her hand up and gently examined the area before releasing her grip. "Looks fine," she said, but her quivering voice betrayed the conflicting emotions raging within her. "Whatever it was, left virtually no trace."

Eden gazed into his eyes and saw the primal hunger burning within them. She could feel his desire building, evident by the rock-hard bulge in his pants pressed against her thigh. Her own emotions were a mix of fear, concern, and arousal as she sensed things were about to escalate. In a quick motion, she removed her hand from his crotch.
