Pheromone perfume. You bought this because it's the 'best selling perfune' from what your bestfriend said. That morning you put it in, not knowing when your boyfriend come in. He stares at you for a second, and you heard back sniff. He was behind you, his nose were on your neck. "You smell really good" He says as you felt his arms wrapped around and his lips on your neck. "Really really good" Before you knew it. You woke up in bed eyes with hickeys and bits all over. "I see why it's the best selling perfume." You mumbled.
