As you play Girlvania you slowly unlock more lewd activities for each of the four girls, as well as opening up access to new toys, outfits, jewelry, and locations. This happens through many stages of “education,” which is a simple yet effective game of pleasing her without being too rough, and then making her cum. These stages are broken up into different activities, and once completed you have free access to play with her all you like, using what’s been unlocked so far, until you decide to move on to the next level of her higher learning.
The sex acts available to the player are many and varied, including boob fondling, pussy and asshole fingering, clit stimulation, and fucking with sex toys. You control the speed with your mouse, or set the naughty act to auto. In either case several actions may be carried out simultaneously. For instance stick a lollipop in her asshole and leave it there; fuck her pussy with a banana automatically at a medium pace; put your hands on her tits and rub up and down manually; put a pocket vibe on her clit watching her legs shake; and finally a penis in her mouth. Or a popsicle. All actions occur in concert all over her form, although depending on her body’s position not every sex organ is open for business.
