First Love

The theme of both titles is similar... The story of Pretty x Cation The Animation & First Love is built on the inner need we all have to build bridges between our soul and the loved one’s soul. Love is not just physical and sex is more than just copulation. If you enjoy one, you should probably enjoy the other. 

Both focus more on loving sex rather than rough sex. Both have brief stories which lead up to the sex scene, and they both are solid hentai, although Lovely x Cation has a much higher production value. 

Both are very different from typical hentai. The couple are monogamous, in love and it is not sleazy. There's no weird tentacles or anything like that and both are based on normal couples. Well, couples that are more normal than the hentai standard.
