Daryl, Marcus, and Jason all sound like perfect candidates for father/son impregnation. Will these nymphs seduce their fathers? if their little brothers look like the fathers, its a manboy, if they look like the male mothers, its a sissy.
Maybe mr. Seedplot would enjoy being a daddy to illegitamate offspring if they all had a sleepover at Billie's and coerced the poor old man until he nearly has a heart attack.
It also may have occured that Andy already produces virile sperm that could get anyone pregnant, and im sure he wont mind becoming a father.
I would have suggested another round of show and tell, when Billie is enormously gravid, and his belly is positively twitching and squirming with movement from his sibling
Make more chapters if you can, or a sequel.
fatherhood is such a wonderful thing, and it would be heaven to see his son show off his big pregnant belly full of his own little brother. All his other little boyfriends taking turns touching and rubbing his womb as his fathers babies kick around inside
This is surprisingly wholesome from the stories you usually write. I like it and I kinda wanna see more wholesome smut like this.
