Sensitive Pornograph

Well, both are yaoi. Boku no Pico is shota yaoi. But both are pretty interesting. 

Ummmm well it's YAOI that's for sure....it's more hardcore than Haru but it's pretty good. I like Haru better though, cause the uke looks like a seme...well basically at first you can't tell who's the seme and who's the uke, which is cool ^.^ 

These are yaoi series, featuring actual sex scenes that do not get cut out in every episode. Another feature these series share, is a younger partner being a university student on a part time job. There is also the reversed dynamic, of the older partner being the "uke", and the younger partner being the "seme". Despite being hentai with sex scenes, they do revolve around a short story regarding the characters' relationships and overcoming obstacles. 

Two episodes of attractive bishounen with a roundhouse kick of smut between them. What else is there to ask for? 

As other has said, this is only Yaoi and not hentai but it's very cute(+ someones getting raped) It includes a man and a boy in a relationship with money in play but it's very romantic too. 

Both are sweet, a bit silly soft-yaoi animes set in the modern world and focused on the relations between lovers. 

This is also Yaoi with the genre of Romance, Comedy and Drama just like in SP. It's recommended and very famous yaoi anime and manga. The first season though is much better I think
