Eric defuses the situation

Before you have a chance to respond, Janet looks over your shoulder and you hear someone move into the room behind you. "Mom, don't you worry about what Mica and I are doing," you hear Eric say. You turn around and see he's putting lowering the gun.

Wait, did he fire it at you? At your sister? You turn back to look at Janet.

(Cassie Del Isla)

She was looking good. She was wearing pump heels akin to those you were wearing. A sibling preference, you've been sharing shoes since your teenage years. She was wearing a cute satin top and a grey skirt. A very professional look befit her station as a model and part time escort. She had Eric at the ripe age of sixteen and she'd just gotten hornier with age.

If anything, you suspect she'd been fucking him for longer than you have, so you were not feeling too worried about this rant she was currently about to have.

"I worry about my little baby boy and the women he fucks," Janet say as she gives him a pouty look. "And you know me and Mica have a long history of fucking around together. Why did you go behind my back to fuck my own sister, baby?"

"Well," Eric said as he put the gun down on a table and walked over to the both of you. "It was supposed to be a surprise for your birthday, but me and Mica had been planning a special surprise," he said as he walked over to the both of you, putting his wide arms across the shoulders of both of you.

"Oh, well... I might forgive the both of you if I get a little sneak peek at my birthday present," Janet said as the three of you began teasing each other. One part of your brain was pondering how you were ready for another round of sex so soon after the last one, but the other just wanted to get back into it. Maybe people got reset after shooting the gun?

Janet was also very experienced at anal sex, but she preferred a little extra lube because she was having a lot of sex as part of her job, so you were helping out with some extra lube as she began stuffing her asshole onto Eric's shaft.

You've both changed to a similarly themed outfit and had been messing about with each other a little while Eric was watching. After a few minutes you've gotten into Eric's (and yours) favorite sort of sex.

"Oh God, why have we waited so long to do this?" Janet asked as she started climbing towards an orgasm. As you were idly fingering yourself while watching your nephew fuck his slutty escort mom, you hadn't really picked up on the question. Some part of you was beginning to worry that you were beginning to lose your integrity, but the other was more than happy to await eagerly to ram themselves on that wonderful cock again.

"You really should start using more lube, sis," Janet said in an admonishing tone as she rubbed a dollop of white lubricant around your asshole while you were getting ready to ride Eric's meat rod. "You don't want to get hemorrhoids because of over-use, trust me!"

"I know what I'm doing, sis, but I guess it can't hurt," you said distractedly as your focus was on the massive cock beneath you. Some part of you wished he would stuff that thing into your pussy and breed you like a bitch, but you did love anal and so did Eric. You moaned happily as you felt his cock begin to expand you, and you had a small orgasm just from hearing him groan at the tightness of your ass.

"Well, I hate to dine and dash, but I really have to get back to work," Janet said as she picked up her purse and gave the two of you a kiss on the cheeks. There barely was any hot water left in the shower, but you've cleaned the worst off of you and Janet had gotten dressed to go back. "We should do this again sometime, sis. I had a wonderful time.""So did I," you say and kiss her on her cheek before wrapping your arm around Eric's waist. "but I hope you don't mind if I keep babysitting a little on the side," you said as you looked up at Eric, who gave you a little peck on the lips.

"Oh I'm sure we'll figure out a amenable situation," Eric said to you and your sister. "I got energy to spare."

"That sounds like a plan to me," Janet said as she looked at her smart watch and startled. "Time flies, I'll see you guys later!" she said as she ran for the door, leaving the two of you in silence. You looked up at Eric and pondered how you were feeling about your current situation.
