Peter has a super quick metabolism due to his mutation, and a side effect of this is an unnaturally high body temperature, making him basically a living radiator which is perfect for cuddles, especially in winter, so you’ll basically drape yourself over him and use him as a portable space heater and he’s Definitely Okay With It because you’re adorable and he’s lowkey needy af so having you constantly touching him or holding him in some way is really nice for him
