I'm looking for a couple of hentai doujins - I don't know their names, but I can describe them. If anyone could help me with a name or link for either, it would be great.

The first one centres around a teen shota whose older sister comes to visit. She constantly teases him with her massive tits, until one day she catches him masturbating to her in his room after he screams her name. Que steamy sex.

The second centres around a girl in a park, who is met by two schoolboys on their way home. They then have public sex, including fingering and double penetration. However, when talking to her, it turns out she is a runaway from home, and is relying on an older guy for support. She then goes on to talk about how this guy has a family and that they have sex whilst his family is out. She then starts following one of the boys home, saying that she left something at this old guy's house and that it was the same way. Then there's a twist - it turns out the guy was the boy's father.

Thanks in advance anons.
