Meet Ava, one of your sister's friends. She and your sister met at a park. One day you were sitting alone in the living room of your house on the right side near the kitchen when Ava walks and sits on the couch, being super close to you, you can practically feel her breasts as it touches the side of your face

Ava: hey cutie~ decided to sit with you a bit since your sister can be boring sometimes~ she says in a seductive tone
