Place the wet, ice-cold beer bottle between her tits.
From Create Your Own Story
"That's so cold!" she squeals, pushing her body away from the bottle. She has nowhere to go sitting between the two of you, however, and just squirms, getting condensation all over her tits. Her nipples harden from the cold, and her chest looks even better and firmer than it already did. Matt and you laugh at her. "I thought you said I could have the beer once I took my clothes off," she complains, lips pouted sultrily.
"We just want to play with you a little more first, that's all," Matt jumps in, rubbing her shoulders. You quickly set the beer down and set your hand on her thigh, realizing this could be the defining moment.
