Cassie and The Girls
Erin and Tia had arrived together before everyone else got there so they could have some core group time before everyone else arrived. The two of them had been friends because of Nessie and Cassie before Erin began dating Tia's brother and now it was kind of like having a little sister whenever Tia was around. Erin didn't mind at all. She'd spent the week moving into her dad's so this party was exactly what she needed.
When they had the thumb on the roof of the tree house, both of them jumped. "Don't worry. It's just Cassie" Erin told her, able to smell their friend right above them. Standing up, she grabbed Tia's hand and stepped out onto the balcony of the second story, pointing up to where the two stood kissing. Tia covered her mouth and began to giggle as Erin just smiled. After a minuted or two, the older of the two cleared her throat to let them know they were being watched.
"Hey there" Erin replied with a knowing look while Tia just lowered her hand and waved, still giggling too much to say anything. "Hi Peter. Bye Peter" Erin said to the Spiderboy as he flew off. "Kissing is so fun, right?" She said to Cassie with a Grin as soon as Peter was gone.
