What would be the plot of your hentai doujin?

[grabjuri]

I would like one of Jenrya with Ruki, and Takato with Juri. Takato's parents have taken the four kids to the lake for an overnight trip. The kids want to slip away and make love, but the adults are keeping too close of an eye on them.______The kids final hope is that Takato's parents will slip away to make love, leaving the kids alone. Sure enough, when the adults think the kids are asleep, they take a blanket and head off to the lake for some privacy._________ The kids use this hour or so to split up into different rooms and make love, When the parents return they aren't aware that Takato's mother isn't the only one with a womb filled with semen. Both Juri and Ruki's wombs have a lot of sperm swimming around inside them as well.
