The first edition is somewhat long, and I plan to keep this and any possible future editions shorter but I’ll have to see how that goes, as sometimes my initial thoughts for a story become longer than the initial thought was as I write, which is what happened with the first edition of this story line.
A couple of months had passed since the day that changed the way Amber looked at sex, and her step sister, and through that also changed Ashley and Steve’s lives as well. Things were going very good, all three of them were getting along very well and had blended Amber into the relationship well. There were still some things that Steve and Ashley did alone like a “traditional” couple, occasional date nights and stuff but for the most part they were all doing stuff together. And to the outside world it just appeared that Amber was hanging out with her step sister and her boyfriend. They were even looking into possibly getting a king size bed to all sleep together at night but were unsure if they wanted to do that yet.
At the beginning, Amber was involved in the sex about half the time, but now it was pretty rare for any type of sexual activity to happen with out her. Usually the only time it happened with out her being involved was shower blowjobs that Ashley would give Steve some days when they got ready for work together if they started their shifts around the same time, but that was about it.
And now they were one week away from Ashley’s 19th birthday and Amber was planning something special. Her birthday fell on a Friday and she requested a day shift at work that day and the next day off. Ashley knew they’d be going out to dinner with some friends but didn’t know what Amber had planned for after that, that wouldn’t involve their friends and that their friends couldn’t ever find out about it, or how much she would absolutely love it.
The day finally came and Amber had planned everything to a T. Including what Ashley was going to wear out for the first part of their night. The normal portion of her plans, as it were. Amber had Ashley both had to work during the day but Amber got out a little earlier than Ashley so she headed home as quick as she could so she could get dressed herself and also lay out the new outfit she had planned out for her step sister.
Amber got home, headed to her room and stripped naked. Stopping for a moment to admire her body in the mirror. Over the last couple of months she had gained much more confidence in her small chest. Steve and Ashley seemed to love her smaller tits and would regularly give them attention. Both during sex and even when they just laid around the apartment together. She ran her hand down her toned midriff briefly, enjoying the feeling of her soft skin. She wanted to keep moving lower but she knew she had limited time and knew she would get all the pleasure she could handle later that night. She went to her dresser and pulled out a very skimpy G-string. She rarely wore G-strings or thongs, much preferring boy shorts or more traditional panties but tonight was special. She then walked to her closet, her toned ass jiggling just so as she did. She knew exactly what she was going for, she pulled out her brand new red dress and pulled it on. It fit her perfectly and accentuated the curve of her ass perfectly, and went to just above her knee but had a slit up to a couple of inches below her ass.Which with the length of her legs, it was a long slit. She didn’t bother with a bra before putting it on, as she rarely wore one anyways.
She then went to the other side of her closet and pulled out the outfit she had for Ashley and took it too her room. It was a “little black dress” that was going to fit her like a glove. She purposefully made sure it was shorter than hers and was going to show off just the right amount of cleavage. She also grabbed a small package with a new lacy bra, black also and a new thong. She then went to Ashley’s room and laid them on the bed with a note that she had to wear everything with out argument and went back to her room.
Ashley arrived home a short time later and headed inside and Steve was on the couch, already dressed up nice but Amber wasn’t in sight. She looked at Steve and asked where Amber was. He just shrugged and said “She said to head to your room and change and be ready in 15 minutes”. Ashley playfully rolled her eyes and headed to her room. Ashley walked into her room and saw her outfit laid out for her along with the package with her new bra and thong. She looked them over real quick and thought “Amber, what do you have planned”.
She stripped naked, and slid on her thong before stopping to stretch for a moment. Her large, perky breasts looking even more perfect as she stretched her arms about her head. She then slid on the bra and admired how comfortable it was. She audibly stated “how the fuck did she manage to get me a bra that fits perfectly and feels amazing. Then pulling on dress, she looked in her mirror and admired how it hugged her ass. She headed out to the living room and she immediately saw Steve’s jaw drop, and she couldn’t help but to also notice his bulge grow. No matter how much kinky stuff they had done together, the sight of Ashley all dressed up still made Steve basically instantly go hard. Which was something that Ashley absolutely loved.
Amber appeared a moment later, looked her sister over, smacked her ass and gave her a deep, passionate French kiss. She eagerly kissed her back and as they separated, Ashley says “easy there, Steve’s already worked up, much more of that, and he’ls going to be on top of us and we’ll be late for your plans”.
Amber nodded slowly and said she was right, and they headed for the door. Both of them purposefully walking with more wiggle to their ass than normal to tease Steve who was walking behind them.
Later that night after a wonderful dinner out, including Steve managing to sneak in sliding his hand up Ashley’s short dress and teasing her pussy over the thin fabric of her thong, the three of them arrived home.
Amber, having a huge smile on her face, proudly exclaimed that she had one more present for Ashley. She quickly bound to her room and came out with a box, wrapped perfectly and with a big bow on it. She came out to the living room where Steve and Ashley were. Despite Steve being a big part of planning the early part of the night, Amber had managed to keep this last present secret from Steve even, which was hard because she knew he would love it also. She walked quickly to Ashley and gave her the box and wiggled anxiously for her to open it. Ashley untied the bow and teared into the wrapping, revealing a plan brown box. She the tore off the tape and opened the box. Revealing a large, 8″ strap on dildo.
