good things come to those who wait. he ain't a cuck and there's no NTR. i understand the appeal of wanting to get straight to the sex scenes but this is one of them that takes a bit of time. and before u get turned off at the thought of waiting 10+ hours for a sex scene. it's not that long.
also, why people love this...won't speak for everyone but for me. 2D animation beats 3D any day. and thankfully the writing is good enough that I'm remotely invested in fucking the girls
