The two of you head to a bar that Heather knows about and after getting in you head to the bar to get your drinks.
Heather looks around "Well do you see anyone that meets your desires."
You start to scan the room seeing all the girls there and you point out an extremely buxom girl "I can see where your mind is going and I kind of like your thinking, lets go over and talk."
The two of you head over to the girl and start to talk to her as you slowly shift the talk to the idea of spending the night with the two of you.
The girl who's name was Anna was all for going with one of you but she was not looking for a threesome so she said her goodbyes and went to the bar.
Heather looked rather disappointed but said "Better luck next time."
As you were sitting there thinking about how to make your next move Heather got up saying "I will be back in a bit" as she walked off.
You follow Heather with your eyes as she headed to the washroom, that's when you see Anna heading in the same direction.

When Heather got to the washroom she made a pass at Anna as if she was willing to leave her friend for her.
Anna let her guard down for a sec. just long enough for Heather to slap the zipper on her, then open it.
Anna just had enough time to make and "OH" before she deflated.
Heather then picked up Anna and went into one of the stalls where she rolled her up and put her into her bag.

You had been successful in finding a girl (Tina) who was willing to have a threesome when Heather came back and suggested the three of you head back to her place.
