Peter was at the tower over the weekend, cause May was on a trip. He mostly hung out with Tony in the lab tinkering on his suit.
"Mr. Stark, could you-", "Kid, we talked about it." Tony warned, "Sorry, Tony could you please give me the screwdriver." He asked quietly. Tony passed it to him chuckling to himself.
"Tony, Peter dinner is ready." Pepper called as she entered the lab, both geniuses looked up then at each other before sprinting out of the lab. "HEY NO RUNNING GUYS OR NO LAB FOR THE REST OF THE WEEKEND!" Pepper yelled at them. The Avengers were met with the sight of an angry Pepper and two geniuses looking like kicked puppies. "What did you two do, маленький паук?" Nat asked, "Mom gave us lab arrest." Peter mumbled sad before freezing. The room went silent and Pepper smiled a teary smile before she hugged the little spider. "I always thought of you like a son, honey. Please never stop calling me mom." She whispered kissing his temple softly. "Never." He mumbled.
"So you're calling her Mom and me still Tony?!" Tony exclaimed slightly annoyed. The whole table full of avengers started laughing. Peter stumbled over to where Tony stood and hugged him. He was slightly hesitant first but then hugged back. "I didn't know you thought of me like a son" Peter confessed. Tony chuckled: "Of course I do. I'm just scared that I become like my dad.", Peter smiled, "Then you're my dad now, idc if you think bad about yourself, to me you're the most coolest person ever." He replied grinning.

When May came to pick Peter up on Sunday and found out that he started calling them Mom and Dad she smiled and got around 200$ from the Avengers minus Nat and Wanda.
