Samantha wants to play it safe for now, but it might not be up to her

You take a condom from the box, the writings isn't in English if you had to guess it looks like Chinese or Japanese from the characters bar a size measurement stating how thin it was, but your brain is far to horny to contemplate this now, you carefully open the wrapper and take out the dark Doreen condom, true to its word it does feel thin. You slowly and rather clumsily roll the condom down your former cock. You've put them on many times, but never when it wasn't your own. It's soon covering Samantha's cock, and she seems happy enough with the fit, as she pushes you onto your back and lifts up your legs.

"Well it'd be rude not to test out how good this feels, after you helped me put it on." Samantha chuckles as she rubs the length of the rubber covered cock up and down the length of your slit. You let out a few moans, you can tell it doesn't feel quite as good as it did, when Samantha did with with her cock uncovered, but it still feels really nice, and you'll have no trouble cumming, if anything maybe you'll both last a little longer.

"Yeah, I mean we basically owe it to each other to see if these are any good if we have to use condoms again." You coo back as you wiggle your hips to tease Samantha's cock with the wetness of your now dripping pussy.

"Well it can't be helped, are you ready dear?" Samantha chuckles as she positions the her cock at the entrance to your pussy. You don't even answer with words but simply smile up at Samantha, you still find it strange looking up and seeing yourself, but from all the pleasure you've had, and to have had almost a full day without arguments or incident, you feel that this has definitely been worth the slight weirdness. You move your arms down and take a hold on Samantha's legs, pulling them forward towards you, forcing Samantha to slowly penetrate her old pussy with your cock.

The feeling is still amazing, although being as turned on as you were also massively helped. Samantha's cock slides in with ease between your own lubrication and the condoms, you look up between your legs and see the dark green condoms disasapear into your hungry pussy, you can see a whitish cream slowly build up, which you assume must be a mixture of the lubricant and your own juices, as you lie back and enjoy the sensation of Samantha fucking you. While you can't feel everything you did before, there is more than enough stimulation to start getting you off, as you feel the increasingly familiar heat begin to build in your pussy, a fire that right now only Samantha's cock will put out.

You look up at Samantha seeing your old face contort and groan in pleasure, and smile as you're glad to see Samantha is enjoying this despite the loss of feeling with the green condom. You toy with the idea of removing it, after all those new pill will be kicking in soon, so you should be safe. You open your mouth to ask only to let out a big moan as Samantha lifts your legs and holds them in the air giving her easier access to the deeper parts of your pussy, not that she needed the help, but it feels good so you won't complain.

You feel your old balls slap heavily against your new soft curvy ass as Samantha bottoms out, you look over to the mirror on the wall and watch as your writhe in pleasure in your new body, seeing yourself move in Samantha's body circa her college years make you smile, you couldn't get enough of her body back then, her long red hair, and her cute freckles face that makes her green eyes stand out, watching yourself make this sexy faces and sounds coming from the girl of your dreams, starts to make you even wetter, you start to wonder if maybe it would be possible to stay like this for a while, purely because having her perspective is good for their marriage, the sex is just a really nice bonus, you lie to yourself.

You look back over to Samantha and smile, you find yourself wishing the condom wasn't between you, and put more consideration to asking Samantha to take it off. You could just ask her to pull out, but even if you didn't and she came deep inside you, you're protected now right, after all Samantha knows this birth control and pregnancy stuff, you didn't want to risk upsetting her by second guessing her, you love her even now in your old body, and you know she loves you too.
