You were watching basketball on the court and after the first round a player come up to you and asked for water, it was Jacob.

"Hey, Do you have any water? I'm pretty thirsty" he asked and he looks at your tumbler that is beside you and grabbed it without even asking for your permission, he then drink the water inside of your tumbler.

He gave the tumbler back and chuckles "no wonder why your water taste good..it's been touched by your soft lips." he said and wink at you.
