Mommy Dearest and Daddy Dearest were your and Gf's parents one day they walks to Gf's and Your Room and opens the door only to see Bf laying on the bed with you and Gf on his lap, Gf was pulling up her hair and Bf just holds your hip as you were just looking at your parents, Gf and Bf looks at them too as Bf gives them the middle finger and sticks out his tongue at them

Mommy Dearest: "oh?'

Daddy Dearest: "hm!"
