It's been three years since the swap and things have normalized quite a bit. The new David adjusted very well and within two years, he was able to build his body of his dreams. Gone was the lean and sorta lanky 16 year old body when they first swapped. When people see David now, they see a muscular 19 year old college jock who is a magnet for girls and guys alike. There are even stories circling how strong of a sex drive David has and how he fucked several of his professors this year to pass his subjects this semester. Rumors are even circulating how he got one of them pregnant recently, but only David and the professor knows for certain if that is true or not.
As for the new Cathy, she has been doing well as a housewife. When they first swapped, Cathy's old body was flabby and tired looking. After the first year of their swap, she resigned herself to her fate and accepted that this is her body now. Given that this body is hers to keep, the new Cathy decided to work on herself and make herself more presentable and less dowdy. She started doing cardio every morning and she started on a calorie restricted diet. Since she makes the meals, this was easy for her but it was also a bit insulting seeing how the meals she prepares for the new David are thrice the servings that she makes for herself. They were trying to achieve two different things, she was trying to lose weight while the new David was trying to bulk up. She misses being able to eat whatever she wants back when she was in her original body, but she blocked it out otherwise it will drive her insane.
After three years of her continues regimen, the results have been very obvious. She lost a lot of her belly flab, and her skin is looking much tighter. She was quite proud of this progress, but there's one person who is happier seeing her like this. Steve was making more and more advances to her especially once she started fixing her appearance. The new Cathy knows that part of her new duty as a wife is to satisfy her husband, but she made sure to take every measure to avoid getting pregnant. It's a good thing Steve prefers getting blowjobs than fucking her, but he's been getting more and more insistent recently.
One night, while Cathy and Steve in bed...
"Honey, I can't sleep" said Steve while caressing Cathy's breasts and rubbing his hardening dick behind her back
"I'm too tired Steve, let's go to sleep" said Cathy who felt more natural calling her former dad Steve ever since the swap
"I want a son Cathy. Please give one to me before it's too late" Steve whispered in Cathy's ear.
Being that Cathy is already 44 and Steve is 49, we aren't even sure if carrying a pregnancy is possible. There are some couples who are able to conceive a child at this age, but it's unusual rather than the norm.
After whispering that to Cathy's ears, Steve removed his boxers and rubbed his 10 inch dick with lubricant that he keeps on the end table near the bed. He then started to rub it first on Cathy's firm stomach, and slowly but surely guided it towards her pussy slit. In a sudden thrust, Steve entered Cathy to which she responded with a loud moan.
"Shush Cathy, not too loud...We don't want David or the others to hear you" said Steve. He made sure to say David's name first as a fucked up reminder that the one inhabiting David's body knows the sensation Cathy is feeling very well.
Steve was mostly doing the work as Cathy is in the mindset that she has to serve her husband. After multiple thrusts, she felt something warm inside her. She knew that Steve exploded inside him, and this was something she never felt before. She never let Steve cum inside her prior to this, so the sensation of having the seed that originally conceived her back when she was still David being inside her was something that clouded her head.
"That was amazing Cathy. I hope you give me a son" said Steve while pecking Cathy a goodnight kiss.
"Am I...going to be a mother?" said the new Cathy silently as she caressed her lower stomach, now filled with Steve's cum.
