To invite more friends over.
From Create Your Own Story
"Why don't we invite someone else over?" you ask. Both Adam and Kara have no objections. You go through everyone in your phone and only find two friends worth calling. Unfortunately, they're exes of each other, so you can only choose one.
Matt is a senior as well, with an older brother who supplies him with alcohol. It could be fun to introduce that element into your night. Of course, he would be all over Kara, but you feel fairly confident she is more interested in you than anyone else after her flirting earlier.
Raven is a year younger than you, with an undeniably attractive body and a tendency to be 'one of the guys'. You have no personal attraction to her; she's just not your type. You can't help but think you could use her to make Kara a little jealous and push things further, though.
On the other hand, you know Kara has some hot friends. She might not be so bored with one of her girlfriends over. You could always suggest Kara invite Shayla Chambers over. Kara's best friend Shayla is nearly as hot as her. Petite, blond, and with a fantastic pair of titties. She's a cheerleader, but also belongs to a regional gymnastic team. Like Kara, Shayla is one of the few hot girls at your school you haven't banged yet.
