Just as Max was going to touch their now shared penis in came their mother in which they both started to pull their boxer's back up to hide it from their mother. "Oh don't be so embarrassed. Remember I had to look at it when doing the operation and besides I saw it when I changed your diapers when two were babies." Their mother told the two brothers.
"Hey mom," Max said. "Yes, Max what is it?" his mother replied to him. "If by some chance we do get a girl pregnant which one of us would be the father and who would be the uncle?" Max asked his mom. "I guess that all depends on the situation. Like if you marry the same girl and get her pregnant you would probably both be the father or if you married two separate women one would be the father and one would be the uncle." Their mother answered them.
"Well like that will ever happen," Max told his mom "No woman would want to date a guy with two heads. Much less when one of the heads is his younger brother." Max continued. "Now Max that is not true," she told him. "If I wasn't you mother I would definitely date the both of you." She continued.
She looked at her sons and got an idea for a sort of reward for going through with the operation. She went over and sat down on the bed and patted a spot on the bed. "Come over here and sit down next to me." She instructed her sons. "Because you two will be getting a lesson in the female anatomy." she continued. Max and Kenneth guided there now shared body over to the bed and sat down right next to their mom.
She then went and took off her shirt then went and unhooked her bra exposing her D size breasts to her sons. "Now of course as you know these are breasts." She told them. "When you two were just babies I use to breastfeed you two with them." She told them. "Do you think they look they look nice? If you want go ahead and touch them but be gentle with them." She continued telling them. They nodded in approval as they both laid their hands on their mom's breasts. "They feel nice and soft mom." Kenneth told his mom. "Yeah they feel real nice." Max said agreeing with his brother.
She went and smiled at her sons as she was enjoying them playing with her breasts. "Thank you boys. Now one thing I like that your father does is suck on them. Now go on and you each take breast and just suck on them." She told them. The brothers then latched their mouths to each of their mother's tits.
While her sons were enjoying sucking on their mom's tits she then instructed them to stop. "Alright guys this is the final lesson." She then went and removed her pants and panties revealing her nicely trimmed pussy to her sons. "Now this right here is a vagina and as you know this is where babies come from." She said as she went and put her her hands on her pussy. "Go ahead and touch it and even put your fingers in it if you want." She told them.
Both Max and Kenneth went and put their hands on their mother's vagina feeling it and prodding it. "It's really is nice looking mom." Kenneth said. "Yeah mom I wish we could put our share cock into it just to try it out." Max told his mom.
"Well I really don't know about that you two." She told her sons. As she was worried since they didn't have a condom and was worried that she could get pregnant from her now body sharing sons. After thinking it over for a few minutes she decided to let them go for it since she did owe it to them. "Alright you can do it but let me get you two ready first." She said as she pulled their shared boxer's off revealing their shared penis. She then went and put hand around it and started to stroke it getting it hard. As soon as it was hard enough she laid back in the bed. "Okay you two go right ahead." She told her sons. They then guided their shared body on top of her and guided their cock into her pussy then started to pump away. Pretty soon their cock squirted inside their mother pussy. Leaving all three of them with big smiles on their faces.
