That afternoon Tiffany and Andy went to the mall. Josh was crushed he couldn't come with them but he had to work at the store. The two siblings enjoyed their ride together. Andy's car wasn't fancy but it had a great stereo system. They sang and joked the whole way. It was more like old times for them but the atmosphere of sexual tension between the two was still palpable. Andy kept sneaking looks out of the corner of his eye at his sister's tits and legs; Tiffany found any way she could to brush her fingers up and down her brother's thigh.
Tiffany had on bluejeans that looked as thought they had been painted on; a checked shirt tied just below her breasts so that it showed off her marvellous cleavage; and black boots with high heels that reached her knees. She played with her boobs the whole way, plumping them up and checking them out in the mirror. This gave Andy a boner that would not quit. He had thought ahead and worn the loosest pair of jeans he owned and tight boxers. Nobody would be able to tell he had a huge stalk on from looking at his own sister.
When they arrived at the mall Andy parked close to the doors and they walked in. They spent several hours looking around shops together. Tiffany and Andy had always gotten on well and they were having a great time. They picked out birthday presents for their dad; Tiffany bought a new bedspread for her room; Andy got himself a copy of a PC game he had wanted for ages. They laughed and joked about things.
The two ran into a few old school friends and had nice chats with them. They all agreed that Tiffany had never looked better and several of the guys tried to hit on Tiffany. She was friendly to them but remained decorous. They figured it was because her brother was around. Little did they know!
They stopped for lunch at a small Chinese restaurant run by a friendly family whose kids they had known for many years. The food was great and Tiffany kept Andy amused by reaching out with her booted leg and running it up and down his calf. He went red from this treatment and had to shift uncomfortably to adjust his suddenly raging cock. Tiffany gave him a wide grin and a wink. She always knew what to do for guys.
"So what are you going to do after lunch sis?" Andy asked, his hand shaking on the chopsticks as he brought some noodles to his mouth.
"I have some private shopping to do." She said while not meeting his eyes.
"Private?" Andy said after chewing and swallowing his mouthful.
"Yeah. I need to pick up a few pieces of... clothing. I'm not sure that you'd want to come with me."
Andy caught on to what she meant. He flushed an even deeper red. He was feeling brave today though and felt like calling his sister's bluff. "I'd love to come with you sis."
Tiffany rolled her eyes before narrowing them. "Okay you DO want to come with me. You're not going to though."
"Why not?" Andy asked looking a little hurt.
"Beeeecause, brother, people are going to look at us a little odd if we're out buying lacy underthings together!"
Andy coughed at the words and almost spat his mouth of Chinese tea across the table. Mr Chu, the proprietor, came rushing across the room and pounded him on the back. Andy finally managed to swallow the hot liquid. He waved the Chinese man away with a warm smile and the two went back to their whispered conversation.
"You're going to buy... to buy..."
"Yeah," Grinned Tiffany. "I got my wages from the movie theatre Wednesday. For some reason a got a nice big bonus in my packet. I must have worked extra hard or something." Her mind went back to the hard ass fucking she had received and she felt her little pussy moisten. "So I'm going to treat myself to some nice new underwear."
Andy smiled and they stood up to pay the bill. The girl behind the counter was a pretty Chinese American the same age as Tiffany and they spent five or ten minutes chatting to her. Tiffany noticed how the girl was shooting come ons to Andy but the lad was completely impervious to them - or maybe he was just ignorant. Either way Tiffany knew she had some work to do with him. She'd suck his cock forever but she knew that he would also need some out-of-family action to keep him normal.
The two split up for a while. Andy went to see a movie, shaking his head in amazement when his sister promised him that it would not be too long a time for her to be underwear shopping. Tiffany was like that. She knew each of the lingerie stores in the mall by heart but she enjoyed going through each individual one and trying on lots of different pieces before buying even a single piece. When it came down to it she knew that having a great body was only one third of the battle to turning on a man fully. The other two most important things were a dirty and inventive brain and a closet stuffed full of the most perfect lingerie to back it up. She had lots of classic pieces already but she liked to update once every couple of months just to stay fresh. Thongs were not always in style; some men wanted her to be wearing plain white panties while others enjoyed silky boy shorts. Although she was a very promiscuous young woman she generally kept her current "boyfriends" down to just three or four. Any more would get exhausting. She always picked out a couple of one-offs from people around the town as well, and then there were the regular party couples whose houses she knew very well. Tiffany loved sex and was not afraid to get it whenever and wherever she could. Some would call her a slut but really she just had a high sex drive and liked to experiment around. This latest experiment with her father and both her brothers was her most exciting yet and really she did not know how she would top it. She may actually decide to settle down with one guy when it was over.
When she met up with Andy at 4pm Tiffany was excited. She rolled back and forth on the balls of her feet and clutched the shopping bags to her chest. He appeared from the crowd dispersing from the movie theatre.
"Good movie?" She asked him with a big grin.
"Yeah. Action flick. LOADS of explosions. GREAT special effects..." Andy was talking with his hands.
"Woman with a chest like two balloons?" Tiffany mocked him, making the shape in the air.
"Actually," Andy paused as though thinking. "Yeah."
Tiffany chuckled. "Always! So aren't you going to ask me how my afternoon went?"
