Creambee - Goddess Knob Trapped - v1.0

This is v1 of Princess Bone Trapped. It's an on-going project where I will be adding more options and interactivity as time goes on. Thank you very much for stopping by and having caress through the options. More sexual positions, playthings and goddesses will be added and voting on these next options will be held on my Patreon page. I haven't made obvious instructions in this version because I like the concept of click and drag, figuring out what to do, for anyone interested here are some hints: pull your penis in the direction of her vag to start fucky-fucky, to fuck-a-thon quicker and to spunk. Pull down to move slower or pull out. Pull her larger futa size in the direction of her hatch to make her selfsuck, jack her off to make her spunk or pull down to pull it out of her mouth. Click and hold near her but and drag in to smack her. For everything else, just click or grope;)

If you have been reading about the adventures of the major characters of the Pokemon universe and you have a good understanding of its lore and mythology, then you'll probably agree that the Pokemon named Hypho is a pain in the ass. However, only this moment can you see that for some attractive ladies, Hypho could be the pain in the ass in a very literal manner! This is all due to his unique ability to place a person into the state of hypnosis deep within. Today is one of those days where he's not in spirit for any fights in the gym so he tries this amazing method on his trainer - gorgeous redhead Misty to have a bit of more kinky fun... however, what will happen following is going to be more exciting to observe for yourself instead of reading about it in the text explanation.

And now about the updates - if you will mopve cursor to the bottom part of game screen you will see a special menu which will grant you quite wide list of customization options so if you are not into blondes you're able to turn this tart into almost any character you want!

Sleeping Kasumi

Who has the most big and well animated boosb in videogame history? Some of you might response Kasumi while the others will have their own opinion. This next anime porn game as it ensues from the title is clearly for Kasumi's devotees. The game is in japanese but since there is not much of a story here it should not be problematic for the player at all. What can be the issue is the absence of player's reflexes because when you find ninja princess sleeping in her space so tired that she did not even got into her sofa and your very first thought is to use this situation to grab her baps then you must have a reaction of Hermes non the less. But you should try it anyway - because even though the game is simple touching, grabbing, poking and undressing big baps like Kasumi's is always a fun.
