Vibromatic Heart Bed

The Vibromatic Heart Bed, introduced in The Sims: Livin' Large, gives your Sims the opportunity to "play" in bed. Send a Sim to turn the bed to 'Vibrate' and have that Sim lie in bed. Then, send a loved one to play in bed. Then they "play", with their Fun and Social meters rising. However, one side effect of this activity is a baby appearing.
