I wasn't referring to the sharing scene with Jen but the scene where she is a sub to the MC
ah my mistake - yeah i did that path once, but felt too try-hard for my tastes. Still, at the end of the day, jen is jen and one of the best next to Lea and Olivia.
It probably won't get on the list because it's a different perspective, but I would recommend anyone here to try out Jessica O'Neill's Hard News anyway. The renders are top tier and you can get 3 hot scenes of involving your partner in a threesome on the faithful route. The caveat being that it's a female protagonist game and all of those are MFF, but I would argue that the desired mentality is still there - it doesn't feel like the practically vanilla (for porn standards) "male MC scores with two chicks at the same time" at all, at least in my opinion. There is a setup for actual swinging in the future, but don't hold your breath on that - the updates have slowed down to an unbearable crawl. Just play what's already there, it's worth it.
Appreciate the mention of Jessicas - indeed I've played it and keep a distance eye at the progress; the writing is decent, and it subverts some of the more common fem-protag tropes. Though, like you said, a turtles pace of development.
While we're on the topic of female protags, I may as well name drop Casual Desires as well. The MC is Asian, but I'll make the bold claim that Daz renders are "western" so it counts. A secondary character you control has a swinger relationship while the MC is still single as of now, though dabbling in a whole bunch of possible flings. A personal highlight would be the strip poker sex scene, which has several variants depending on who you invite - my fave being a foursome with two childhood guy pals + a female virgin friend with an obvious crush on you.
Its main con is that it's very slice of life, and as I've realized while playing a lack of real plot or drama in between the sex scenes can potentially make things boring. Thankfully the author's newer game Rebel Duet fixes that. Granted, the plot/writing is extremely anime inspired, but Val is worth it. Also, male protagonist option! As for the content, sharing is coming in the upcoming update within a month or two.
Casual Desires is a game I'd recommend to everyone once.....I didn't add it here though because in my mind it's a through-and-throughout fem protag game. I think the only other real (sole focus) fem protag game I have is "Cure for Madness", but I've a soft spot for that one as there's so much focus on her relationship with the boyfriend, and contains my favorite sharing scene out of all games period.
The strip poker scene was enjoyable, as were the swinger scenes -but I'd venture (as you recognized) even with western models, everything else about it is very anime-esque, the underdeveloped bodies, their day to day activities, the style of "corruption" or relationship progression. I feel like you could change it to an HS or KK game, keep the exact same script and the experience would be similar. Sidenote, I've also kept a careful eye on Rebel Duet, but so far nothing that would warrant it as a sharing game recommendation. Still, a fun little experience.
At some point I should probably start a fem-protag (but with swinging/sharing elements) section; there are a few here in addition to Jessica's, stuff like Kate's or Her Desire.
