Of course you try Lisa's idea!

You grin mischievously. "Yes, I think that idea will work out just fine."

Before you can make a move, Lisa pushes you backwards onto the bed Amy's sitting on and straddles you, leaning down to kiss you aggressively. Amy squeals excitedly, grabbing at Lisa's shirt and yanking it off quickly. She kisses Lisa's neck as you and Lisa make out aggressively, and when you open your eyes, Amy amazingly is completely naked. She grins at you with a look of lust you've imagined since you met her, and she forces her mouth into your kiss with Lisa. The three of you share a passionate intertwining of tongues and lips, your cock aching against your khakis.

Lisa leans to the side and her hands quickly pull off your shirts. Amy leans forward, kissing you and pressing her hands against your chest as Lisa makes short work of your belt. She yanks hungrily at your pants, pulling them off, revealing your already very erect cock. She looks at it lustfullly, and starts unbuttoning her jeans. Amy twists to face her, kissing her wetly as Lisa slides out of her pants.

Amy, however, is apparently done waiting, and she grabs Lisa's shirt and pulls it off, her hands deftly unstrapping Lisa's bra as well. The two girls break their kiss and look at you, both smiling, both of their hands sneaking between their legs.

Amy finally speaks. "Which one of us do you want to fuck first, John?"
