Henry thought Kirstin might join him in the shower, but his stepsister left him alone this time while he cleaned himself up from fucking her in the ass.
Once clean, he dried off and left the bathroom to find Kirstin waiting in the hall. "My turn," she said.
"You could have conserved water and joined me again," Henry pointed out.
"Yes, but I thought we could use a little break. Speaking of which, a couple of my friends are coming over to work on an econ assignment that's due Monday, so we're going to have to put our little fuckfest on hold for a couple hours. You don't mind, do you?"
"Do I get to watch?"
Kirstin giggled. "If watching three college freshmen do an assignment makes you hot, go for it. This is legit, Henry. Though I have to admit, Carlene's kind of cute. I wouldn't mind getting a piece of her."
"Getting a piece? You've been practicing talking like a guy?"
"It makes some of the men I know pretty hot to hear a woman talking like that about another woman. Anyway, go get some clothes on, big brother. I don't want my friends to see what they're missing. I'll be out of the shower in a few."
"You don't have any clothes with you."
"I figured I'd flash you one last time after I clean up."
She went into the bathroom and shut the door. Henry found the clothes he'd taken off the night before and put them on. While Kirstin was with her friends, he would probably go back to his apartment and change. The night before, he hadn't brought any extra clothes with him. He hadn't planned on spending the night at his dad and stepmom's house; he'd been asked to keep an eye on the place while they were away for the weekend, but had figured he would just do a quick stop and then go home. His sexy stepsister had changed his plans.
Kirstin was still in the shower when the doorbell rang. Henry opened the door to reveal two girls, one blonde, one brunette, neither as hot as Kirstin. "Who are you?" the brunette asked.
"I'm Henry, Kirstin's stepbrother," Henry replied. "Who are you?"
"I'm Una, and this is Carlene."
Henry studied the blonde. Kirstin was right, she was pretty cute. A brief image of Kirstin and these two girls in bed with him flashed through Henry's mind, but he pushed it aside before his cock could get hard. "Come on in," he said. "Kirstin's in the shower."
"No, I'm not." Kirstin came down the hall wearing a pair of short shorts and a tight, cropped tank top. "Okay, girls, ready for some exciting econ?"
