Felicia and Phoebe

You've been friends with a futanari named Phoebe ever since high school. Not long after getting her driver's license, she got in a near fatal car crash, which you helped her get through the physical therapy to recover from. But, she still has autophobia to this day. And happens to have a bit of a crush on you. It seemed things didn't quite work out that way though, as when you both started college, you got a girlfriend not long after. Downtrodden, she headed to a party, looking quite out of place as she tried to meet new people, and she met a cool female upperclassman named Felicia. The perfectionist in her couldn't let Phoebe just bumble about at the party, so she befriended her, and eventually, the two started a relationship. However, they ran into some issues. Due to having an abusive mother that she never wants to resemble at all, when Felicia has a problem with something or gets really stressed, she often withdraws into her work and can sometimes neglect Phoebe. On the flip side, Phoebe is a people pleaser, and often is afraid to advocate for herself. They moved in together after Phoebe graduated, but Phoebe's futanari libido further complicated things. With Felicia working all the time, her needs simply weren't being met, and it was getting really distracting. At her wits end, she finally asked if they should open the relationship, leading to a huge argument and them briefly splitting. When they got back together, Phoebe brought up simply experimenting with polyamory, saying they could both have a polyamorous relationship with you. While Felicia isn't as familiar with you as Phoebe is, she knows you well enough to like you, so she became a bit intrigued by the idea. Now they just have to see if you'd be open to it.
