Greg tries to bring Lucy

Before starting the car, Greg remembered that Lucy was really enjoying humiliating Meghan and she didn't get to spank her when Jason came so he went back in to bring Lucy but saw that she was flirting with Jason. Greg really thought that using Meghan he could get inside Lucy's pants but seeing this he realised she was probably going with Jason now.

He cursed himself for calling Jason and went back to his car.

"Did you forget something? Why did you went back in?" Asked Meghan

Greg was feeling angry and Meghan was the only one he could take out his anger on.

"Get out of the car, your diaper is getting changed."

"What? Out on the road? What if someone sees?"

"Not my problem. But I can't have you soiling the car."

Meghan reluctantly got out of the car and was removing her diaper when she saw Jason, Millie and Lucy getting out. They saw her too and started coming in her direction. Greg however was unaware of the approaching audience as he was facing Meghan with the packet of diaper in his hand.

When Meghan removed the soiled diaper, Greg handed her a new one from the packet.

"Oh don't you know that you have to wipe her first."

Hearing Lucy's voice Greg turned back hoping she wanted to ditch Jason and join him but when he saw that Jason and Millie were there too he got disappointed.

"Well Lucy tells me that she is your step sister and you were lying about her being Barbi. You know Greg if there is one thing I hate the most it's liers so I think there is a punishment waiting for you." Said Jason as he snatched the packet of diapers from Greg and handed it to Millie. Millie grabbed Greg's arm and pulled him aside.

Jason faced Meghan now and told her that he remembers her now. Meghan was turning crimson now with shame as her crush was talking to her while she was bottomless holding a diaper and covered in piss. Lucy handed a wipe from her purse to Jason and he bent down and started wiping all the piss from Meghan's crotch.

Meghan wanted the earth to swallow her but she didn't have the strength to speak anything she saw beside her that Millie was stripping Greg and felt a little better that Greg was getting what he deserved.

Greg was really **** to remove his clothes in the middle of the streets but Millie was quite convincing and he couldn't muster up the courage to stop her. But as he was down to his underwear and Millie tugged on those he realised if he didn't speak up now his life might be ruined.

"Please stop Millie."

"Oh didn't you hear my brother? You are being punished, you don't get to stop me and besides your appendage really isn't for big boy briefs. Diapers will suit you better."

Greg tried to pull on his briefs but Millie caressed his chest and his grip loosened and Millie was able to strip him completely naked. He heard Lucy laugh and looked her way she was pinching her thumb and index finger in a well known sign for tiny penis. Greg got embarrassed and covered his dick with his hands. Millie handed him a diaper and he realised that he had **** now. Just moments ago he held power over her step sister and was planning on scoring with either Millie or Lucy but know both of them were laughing at him and he was in the same position as her sister.

Jason had cleaned Meghan crotch completely and was paying special attention to her pussy. She was groaning as he was practically fingering her. By the time Greg wore the diaper, Meghan was cumming.

The step siblings realised that these coming weeks might not be as fun as they thought at first.

Jason finally left Meghan's crotch and she quickly put on the diapers. Jason gestured the step siblings to follow him to his car and they did. Jason got in the driver seat and Millie and Lucy got in the second row while Greg and Meghan were **** to go in the last row which were kid size seats.
