Her Sister's Mother. Mature Futas, #53

Eli was Sarah's adopted sister, but the brunette loved her as if she was blood. The two of them had grown together, and there was no one more important in their lives. Which was why, when a woman appeared claiming to be Eli's biological mother, Sarah was a bit wary. Thankfully, it seemed that Valerie was telling the truth, and Eli truly was her daughter. A few meetings were enough for all of them to start to get to know one another, and things began to settle. Or they might have if Sarah hadn't started to feel attracted to her adopted sister's mother.
There were so many reasons for her to avoid feeling like that - from the age gap between them to the taboo, almost forbidden nature of the romance she found herself craving, but she couldn't help but feel drawn to the older woman. If Val didn't feel for her like she did, maybe nothing would have happened. As it was.
