Despite being able to contend with the likes of the Hulk and lift an entire building's worth of debris, Peter found himself overwhelmed by the powerful weight of Gwen's buttocks. Each time Peter tried to lift the huge, plump butt cheek that was pinning him down, he buckled, which resulted in the fleshy orb flumping back down upon his now tiny form. Evidently, he couldn't escape from his imprisonment under Gwen's butt that way so he decided to change his approach.
Peter figured he would try to army crawl his way out. It took him a gruelling fifteen minutes of wriggling and squirming, but eventually, he managed to slip out from beneath his sleeping girlfriend's behind. He took in the sight of Gwen while his own heart pounded from sheer exertion, she remained fast asleep and totally oblivious to Peter's predicament.
Whilst he caught his breath, Peter considered whether or not to add Gwen's butt to his list of powerful entities that he'd bested in his time as Spider-Man but decided that he would rather forget that his pummelling beneath her backside ever happened.
Undeterred by the aforementioned mishap, Peter resumed his quest to get Gwen's attention. This time around, he went right up to her face. The warmth of her breath washing over him, Peter called out to Gwen, "Hey! Gwen! It's me, Peter! Wake up!" However, her response was but a mere snore and she remained blissfully unaware of what was going on right under her nose in the waking world.
Though growing a little frustrated that he seemingly couldn't wake Gwen up no matter what he tried, Peter persisted. His next course of action was ambling further up Gwen's pillow and gently tugging at a strand of her flaxen fringe. "Gwen! Wake up!" His words hung in the air, accompanied by the faint scent of Gwen's shampoo. This method elicited a strong response from Gwen, though far from the one Peter was hoping for.
The giant girl stirred in her sleep once more, a faint smile playing on her lips and with Peter's heartstrings. This affectionate distraction prevented Peter from noticing the colossal hand that was hurtling towards him until it enveloped him entirely. Gwen's fingers wrapped around him, enclosing him in a surprisingly tight and tender grip, and she pulled him close to her chest, cradling him as if he was a stuffed animal.
Peter's breath caught in his throat before feeling the gentle rise and fall of Gwen's breathing against his miniature body, the rhythmic motion and thudding lulling him into a sense of comfortability. If not for the pressing situation, Peter would gladly drift back to sleep right here and now.
However, once Peter finally did attempt to escape Gwen's clutches, he became acutely aware that this wasn't such a serene scenario after all. Gwen's hold of Peter was unyielding. With each attempt to wriggle free, her grasp tightened further, constricting around him until it became stiflingly claustrophobic. The pressure against his body intensified and he realized the impossibility of climbing out from Gwen's hold.
However, Peter realised that whilst he couldn't escape outwards from Gwen's embrace, he might be able to escape by heading further inwards. He had one lifeline, one way out from this constricting situation. The only way that Peter could escape from Gwen's unrelenting cuddle was venturing into her cleavage.
