He turns into spider-gwen

He walked up to MJ, the case of spiders sitting just behind her. As he started taking pictures, he told her it was for the school paper. MJ, as beautiful as ever, smiled and agreed to let Peter photograph her. He snapped several shots from different angles, focusing on her expression, trying not to seem too nervous.

he was taking the photos, one of the spiders from the tank behind MJ managed to escape. It crawled up Peter’s leg, all the way to the back of his neck. Without warning, it bit him—then quickly scurried back down and disappeared into the shadows.

The bite's effects began spreading slowly through Peter’s bloodstream. By tonight, the changes would begin.

The rest of the trip went smoothly. Later, as they left, Peter turned to Harry and said,

"There. You happy now? I talked to her."

Harry just grinned, and Peter waved him off.

"See you tomorrow," he added, heading home.

When Peter arrived at Aunt May’s, she was already cooking dinner for the two of them. But something felt off. Peter started to feel strange like something inside him was shifting. Trying to hide it, he rushed through dinner and hurried to his room.

That’s when the real change began.

His entire body started to shift his features, his frame everything was slowly becoming more feminine their body starts growing breasts about a d cup as they grow they stirp of their t-shirt it it was getting to tight around them growing his head changes as it gets more feminine as well as their hair changing clours to blonde and growing longer. Their vision gets better to as they will no longer need glasses as voice slowly get higher and more feminine as more he becomes a she the more pleasure they feel as next part to change is their legs and ass as their legs start getting smaller and softer as their ass starts to gradually increase size to be about the same size as their breasts once that all done the last thing to go and luckily Peter as been knocked out for this entire transformation as if they conscious for what about to change they would of used it before hand as their cock is next to change as it gets smaller and smaller as their balls also turn into their new pussy once the changes were all done she wakes up to see herself in the mirror and what has changed
