Next are Emma's parents.

When Emma's parents ring the doorbell, her mom greets you with her tits out and a big, cheery, smile. Her father is stroking a huge bulge under his pants, but is also looking over his shoulder to check for neighbors. Both of them are excited to see you and their little girl again, in fact, they're looking forward to seeing a lot of you. The extra car in the driveway doesn't seem to dampen their spirits, if anything, they seem eager to make some new fuck buddies.

Since your own parents are sitting in the living room, trying their hardest to appear like normal, sexuality-suppressing, family units, you quickly tell Emma's parents to go full stealth for a few minutes. You quickly mutter that this is a surprise for their daughter, and that your parents wouldn't take kindly to seeing their son's girlfriend engaging in ****. Thanks to Slave4U, they're able to get straightened out, if fidgety, then you make a big show of welcoming them in, introducing them to your parents in the living room. You shoot off a quick message to Sophia to get Emma home as soon as she can.

Now, you're on a timer. You need to get your and your girlfriend's parents as hot and bothered as humanly possible, before Emma gets back. The way you figure, you've got about 20 minutes before the two ladies even notice your text, and then another 20 before they get back.
