The forbidden Fruit

You make your way home last day of college and you turn 19 today as well. So you know your mum has been making a huge deal of it all week. well, we say mum but in fact tt's more like a Foster mum due to the fact that you were at pre-school and your real mum and dad were killed in a horrible road traffic collision. After a few months, you were placed in care with Kirsty who at the time was 24 and you were only 3. Kirsty had done everything for you made each birthday as it was a milestone birthday. She would go to the ends of the earth for you. Nothing was ever too much trouble as long as she made you happy.You always knew what happened and Kirsty would happily talk about it when you were ready to discuss anything about the accident as Kirsty knew all about it when you was placed in her care. Kirsty was blonde hair length to her back 5,7 blue eyes went to the gym so she had a nice toned body a nice round ass and E breasts still nice and perky too. Her wardrobe one day she wear nice tight yoga pants thats made her ass look perfect with crops tops that show alot of her body off to other days in jeans an usual tops to summer dresses. Then for special occasions a stunning elegant dress with tights or stockings and some stunning high heels. Ever since you started puberty you slowly developed feelings for Kirsty but you never really acted on it as there was always the mother feelings there as she pretty much looked after you all of the life you known. So you get Home "mum I'm back.....mum?....hmm must be at gym".
