Peter gave a small laugh and smile at her words, preparing to go for another kiss after she finished her last sentence... until Aunt May rushed in. His hand and forehead felt much colder... He watched Aunt May hug and embrace Lexi, and when she started yelling at her Peter stood up, but only that as Lexi started to respond... He couldn't help but feel that she wasn't only talking to Aunt May... 

Aunt May gave Peter a look he didn't really understand, then went in to the kitchen. Peter gave a shrug and a smile. "That's Aunt May for you... but the best thing about being best friends with Spider-Man..." Peter started, and made sure the kitchen sink was on before using a web shooter to pull Lexi gently towards him, putting his arms around her than giving her a quick but very passionate kiss. Pulling back a bit. "Is that i know very good places where a couple could get away from it all... Beautiful views of NYC..." He said quietly, smiling at the idea.

He didn't know if she wanted to be coined as "Peter Parker's girlfriend" just yet... but he knew that he was absolutely crazy about her... It took him so long to realize that she was the only one he wanted to hold, to kiss, to tell his secret to... but now that he did, he didn't want to let her go.
