How did you get in this situation? You don't exactly know. All you know is that you're definitely not complaining. You're currently smushed in-between the four of them on the couch, Raphael on the bottom as your seat, Leonardo on your left, Donatello on your right, and Michaelangelo with his head on your lap. Needless to say, they all adore you, and why wouldn't they? You're theirs, their love, their partner, their everything. You treat them like they're people and not just some Mutant Turtle Ninjas. They are yours, and you are theirs.
Raphael was calmly holding you in his lap, his large hands gently resting on your hips, careful not to poke you with his shell, which was very spikey on some parts.
Leonardo was for once being calm as had one arm around your shoulders, the other resting on Michaelangelo's shell. He wasn't making any jokes right now, oddly enough.
Donatello was also being calm, for once not talking only about science stuff or bragging about his inventions as he had one arm wrapped around your waist, the other on the armrest.
Michaelangelo had his head laying in your lap as you pet his head, he liked the attention. He was smiling brightly as his eyes were closed and he was comfortable.
