I just wanna promote PPmaq's new Gayme "SlimeGoon" a little since it's a really nice diversion and helps with sexual urges, i.m.h.o. - lotsa others out there, too, that have a similar concept, but I think for under 7 USD, it's pretty decent and affordable price (itch.io has it at 10% off right now and there's still the Kickstarter Campaign running) and offers enough variation to not get boring too quickly despite the repetitive gameplay - I mean, cum on: we're all doing repetitive stuff when horny and on our own, too. Might as well add a little inspiring variation to it.
So, yeah, there's also a Demo available, which is pretty much the whole Game showing its concept right now only (alpha-stage I'd say). But it's nicely animated, buff studly guard and gooey slime in shifting shapes. Also, feel free to leave some Feedback for improvements there - PPmaq has so far been pretty cool artist/dev, I've found.
