handy bag of popcorn
When at the movies and the popcorn is running low, poke a hole in the bottom of a bag and stick your wang through it. When your gf reaches in for another mouthful, there will be more than just popcorn. She will be eating out of the bag for the rest of the night!
Things were a bit dull while I was at the movies with Sydney, so I decided to bust out the handy bag of popcorn on her. She gobbled it right up!
