Koukan Renshuu (“Exchange Practice”) Zenpen + Kouhen (“parts 1 + 2”) [English], by Uten Ameka
I’m always wary when it comes to swinging (y’know, swapping partners), and having to keep my guard up dampens the fun I may get from reading.
So if you’re like me, I’ll throw this mild spoiler: there’s a happy ending, no couples were broken. Phiew.
We’re with a relatively typical story, two highschoolers are dating, but the boy’s low self-esteem leads him to suffering from erectile dysfunction, he feels he’s no Man enough.
Anyway, come the friendly classmate and his gyaru girlfriend, they offer to try swapping to resurrect the beast inside the male MC.
To my surprise, it worked!?! O_o Sure, the male MC disliked seeing another man inside his girlfriend, sure, the girlfriend got used to more liberty than he’d like and she does it raw with the other guy (so, yeah, you are welcome to rant), but his little buddy came back to life, and his girlfriend, well, she stayed his.
All of that coming with intense, generous, meaty, pretty well drawn sex. Mostly vaginal, plus healthy bits of paizuri, and a few other things, with tolerable amounts of censorship, nice!
I hope you’ll love the read, thanks a lot to CapableScoutMan, NSFWSB, Ro, Rigg, Danky and Hobohobo, from RedLantern TL!

Uh, well, okay, not ‘stolen’ per se, but… ongoing, ignoring requests to use protection, and thanks to that not without some STD dangers and looming questions of parentage.
No ‘stolen’ as such, but you should probably add some caveats as this ending isn’t nearly as ‘vanilla resolved’ as your other ‘the swapping is okay here’ shares, Oliver.
love when you post ones with swinging in it.
Truthfully, the ending still bugging my feeling. the ending have some NeToRase vibe, because the girlfriend still having sex with the buddy and even ignoring request to use protection. I hope the boyfriend do the same with the girlfriend of his buddy. …. and oh well,,, thx for the share
Yeah, it’s drifting in that uncertain mist of ‘cheating’, ‘NeToRase’, and/or ‘Cuck Fetish’ by the end.
I suppose, once in a while, not having a clear-cut and definite ending to a scenario involving partner-swapping, swinging, etc., is fine, too.

I did not read it, I simply enjoyed it.
