No!

Vince was many things but willing to get training from his stepmother was something that was a bridge too far for him. He took a breath before shaking his head as Summer smirked.
"N-no thanks mom I don't need that."
"Aww so cute! You want a futa to get the real experience popping your cherry, don't you?"
"I don't have to answer that."
"Well see you at dinner! We are having roast!"
"Sounds great!" He said retreating to his room and sighing. Much to his chagrin he did almost instantly look up porn on his tablet and watched videos of futas railing males until they were sure they were pregnant. Though in reality they had both probably taken some form of protection to keep that from happening. Though that being said pregnancy was also a huge kink for futas and femboys though not one of his favorites he had seen a few pregnant males getting their backs blown out by their futa doms before. He sighed jerking off his tiny dick for a bit he came twice the majority of males had little refractory period but had almost no true cum tanks, unlike their futa partners. He sighed as eventually dinner was called. He changed put on fresh shorts and panties not covered in cum. He ran down almost tumbling down with Sarah, even if both of them where adults they still acted like young siblings as they fought to get down first, both hissing at the other one before sitting down. After a silent prayer they dug in feasting on rare roast, milk and bread. Before finally finishing Vince sighed he was out of chastity, not bred and could jerk off as much as he wanted after this.
"So! Did anything else happen today?" Summer asked as Sarah paused.
"I came in first in swim."
"That's great!"
"Impressive. We made another deal in work and profits are up. That and the dumb males that the other side bring in keep trying to seduce me. It's annoying." Rochelle sighed as Vince flushed thinking of someone trying to seduce his mother even if she was a futa as Summer grinned.
"Take any of them up on it?"
"I face fucked them. But nothing else. They really were not good at it. I had to do all the work and now I'm annoyed and pent up." Rochelle fumed as Summer shot Vince a wink.
"I think I know someone who can help with that~"
"Dear I love you but you know when I get like this, I need to dominate not enjoy a easy suck. So, I don't think you can help-"
"What? Oh no! Not me I was thinking that Vince could help you! You are his mom as well and it's a son's duty to help his mom when she's in need right?" Vince spat up his milk so did Sarah both looked like they had been stabbed as Rochelle blinked owlishly before sighing.
"If he wants to suck off his mom I won't say no."
"You won't!?" He asked as she sighed, she gave him a knowing look then his younger half-sister, neither of them where children anymore, the youngest age in the house was now legally an adult and there was no sense in not making her carnal wants on the front.
"Vince, I love you, but you are a virgin male at your age, futa moms and sisters helping them out to learn how to please cocks is not odd, this kind of thing is natural in many houses. I won't **** you, but it would be a big help. Just think on it, if no it's fine if yeah just meet me in my room after dinner." She said yawning as Sarah and Summer both gave him mischievous and scandalized looks as Summer smirked.
"So~ Vince, you are a big boy now, you want to help your mom out or what~" Summer asked teasing him once again as he gulped and replied?
