man, i don't know. how big is yours? you can google penis. and then you can bring it in context with fiction, the characters body height and relativity. there are plenty of bigdick kid games. you want your game be one of them? if so, you don't need much story because your mc will be so happy to finally get fucked by a real "man", because the husband is so tiny. zzzZZzzz. a summary of 80% of the games in this category. i think making them big enough is good, so the graphic creator can put them into all kinds of sex-positions. but ridiculous
elephantiasis boners will take away some audience that focus on the mind break, corruption and seduction part. dude, just my thoughts. i told you not to listen to any of the stuff around here.
. p.s.: i guess that's why people disliked the extrem big tits in dating my daughter. it becomes sexy enough because it's taboo not because of unrealistic body parts.
