Tina stood in the entry to the kitchen and watched her mother walk to the front door to answer it. Sadie opened the door and it was her twin sister, Bev. "Hi sweetie," Bev shouted as she burst into the living room and gave her sister a big greeting hug and a kiss on the cheek, "How are you sis, you look great."
The two exchanged small talk for a moment then Sadie called to her daughter, "Tina honey, come say hi to your aunt Bev".
"Hi," Tina said, walking to greet her aunt, "good to see you." Tina's aunt walked over to meet her and gave her a big hug.
"WOW," Bev remarked, "Our little Tina isn't so little anymore." Aunt Bev held Tina's hands and looked her up and down, "Beautiful, just beautiful." Bev's eyes settled momentarily at her niece's pointing nipples that were just distinguishable through the sheer dress.
"You're just in time for coffee," Sadie said with a sly smile, knowing the dirty thoughts that were going through her sister's mind. Tina followed the pair into the kitchen and watched the women's asses jiggle as they clopped along in their heels.
Sadie's sister was in just as good of shape as she was, huge tits, muscular legs and flat stomach, but her clothing and makeup were much more gaudy and tacky. Bev had on cheap clothing that really was intended for a girl rather than a 40 year old woman. She was wearing a very short, tight, red skirt with a tight, white top and a red bra underneath; shiny, white pantyhose and tall, red platform heels. Basically, she looked like a hooker off the street.
After coffee, Tina helped her mom bring Aunt Bev's luggage up to her mother's room, then the trio headed into town for some shopping. Sadie and Tina spent most of their time in upscale shops, while Aunt Bev hit all the discount stores buying armloads of cheap, slutty trash. At the lingerie store, Tina and her mom picked up a few pairs of thigh high stockings in various colors, while Bev bought pantyhose.
The day went along nicely, men stumbling over themselves, gawking at the women, pissing off wives and girlfriends all over town. After dinner out, Tina, her mom and aunt headed home. On the way, Tina thought about the two women in the front seat, they had been very touchy feely with each other all day, lots of petting of hair and slaps on the bottom, lots of sexual innuendo and open discussions about lesbian sex. Tina knew they'd be sharing her mother's bed and wondered if they were going to fuck each other that night.
By the time they got home Tina was so horny thinking about the two twins that she headed straight to her room after a quick goodnight, hoping her sexy mom and aunt would follow shortly so that she could spy on them. Tina dropped her dress and sat at her vanity in her half bra and garter belt, waiting to hear the two come up the stairs and enter her mother's room.
While she waited anxiously, Tina put a fresh coat of lipstick on her thick, red lips and then began coating her tender nipples with the glossy makeup as she had witnessed her mom doing the night before. "Oh god, hurry up", Tina whispered, "I can't wait to see what you're going to do to each other."
Tina reached between her open legs, put her fingertips on each side of her clit and pulled up and out, drawing her growing clitoris out of it's sheath and parting the lips. She leaned her head forward, filled her mouth with saliva and let it drool from her tongue in a long strand onto her crotch less panties, long hard clit and all over her open pussy lips.
"Mmmmmmm," Tina murmured to herself, rubbing her pussy and watching herself in the mirror. Then she heard their footsteps up the stairs and into the room across the hall. As Tina heard the door close, her heart was beating faster and faster with great anticipation and lust for the scene she hoped to witness.
Very quietly she left her room, tiptoed into the bathroom and pulled the tall, leather chair up in front of the secret, sliding door hiding a two way mirror her mom had slyly pointed out to her yesterday. With a deep breath and a trembling hand, the pretty young blond slid the door aside and leaned back to watch the "show."
She didn't have to wait long for the action, Tina's mother and her mom's hot twin sister were already out of their dresses and were standing directly in front of the mirror, desperately kissing each other and clutching wildly at each other's huge, flopping tits. Sadie yanked her sister's head back by pulling violently at her hair, while twisting her thumb sized nipple and pulling it far out away from the breast.
