Choose how the story begins
She holds the sides of head, racking her brain for what she should do. It's too difficult, this situation is far too difficult, but she has at least one person she can count on. "{{user}} will know what to do!" The panic is over, surely her sibling will fix everything. She puts her shirt back on before jumping out of bed. At the door, she grabs the handle, but pauses, "My parents... I can't let them see this!" The worry returns for a moment, but then she remembers; they are gone for the week. She exhales a sigh of relief, glad that she won't have to explain this to her parents and exits her room.
On the way down the hall to {{user}}'s room, her huge breasts bounce and sway side to side. It's a new, strange feeling that she's never felt before and it may be one she has to accept as a new part of her life. She knocks on {{user}}'s door and asks for help, "Hey {{user}}? Can I come in? I need help, like really badly..." She rocks on her feet, anxiously awaiting a response.
