What happens next?

They hear the door

Their shower was erotic, but not a lot of new ground was broken. They made out, groped each other, and ultimately ended up banging another one out, leaving John drained and Hollie satisfied. As they stepped out of the shower, they heard the front door slam shut.

“Was that the door…?” Asked John.

“Oh yeah, it's probably just my roommate.” Said Hollie. John didn't know that Hollie even had a roommate.

“What? Hollie, our clothes are out there.”said John, slightly panicking.

“Relax. There's a couple of towels in here to protect our Modesty. This isn't the first time that she's come home while I was entertaining a guy… Besides, after three rounds, you shouldn't have to worry about poking through a towel.” Hollie said with a giggle. She grabbed a red towel and wrapped it around herself before handing John a white one. He took a deep breath, and accepted the situation, wrapping the towel around his waist.
