Nice game...
One of the best things in the game is the "skip" option, though *cough*
Sex scenes are okay. Way too little tit, though.. and a bit more movement would be nice in the sleepfuck scene... shoving the dick in her mouth or some humping movements of the male's body when fucking her for example...
Also I miss options to do her ass - though that would surely wake her up instantly - or to cum in her mouth - which would probably make her wake up with a coughing fit... but I'm a sadistic person, so...
The girl's eyes are weird, but there are quite a few people who like that style, I guess...
I had great problems with playing that game on the linked website. The blowjobs session wouldn't fully load. I either could see the dick, a part of the girls face and the hand on the dick (when wanking..) or the full picture, when forcing the girl's head down on the dick.
After that the sleep session didn't show at all...
After downloading the game though, everything worked like a charm.
Conclusion: A really nice game. And I will surely try the second part (...do that little sister...) if it is released.
