"Parody of the Nō Play Chōryō" (elsewhere) or "Parody of Huáng Shigōng and Zhāng Liáng" (David Waterhouse, The Harunobu Decade, Hotei Publishing, 2013, v. 2, №651). "The story [...] is about an encounter between the Chinese government minister Chôryô (Zhāng Liáng) and the legendary elder Kôsekikô (Huáng Shigōng) in the 3rd century BC. While riding a mule across a bridge, Kôsekikô dropped his sandal. Chôryô returned it to him. As a reward, Kôsekikô gave Chôryô a book of military strategy. Later, Chôryô helped to establish the Han Dynasty (207 BC-AD 220)." [The Walters Art Museum]References:

As Japanese Erotic Fantasies put it: "a couple engaged in love-making, their stare fixed outside the picture plane". This is the only image of series that has a reference in available western literature, and the only one found in museum collections: Rijksmuseum Amsterdam (RP-P-1999-2001-16); reference: Fukuda (ed.) (1990), pls. 11-2.
The scene of this print looks quite similar to that of the Kiyonaga's Sode no maki:
The woman is "a young lady-in-waiting of Shogun's Court or Daimyō's Mansion, enjoying a rare outing from her tedious chores" [Richard Lane]. She is fully dressed in her outer cloak (shikake), white paper hat (agebōshi or tsunokakushi), and toed socks (tabi). A book or maybe, onkotogami (roll of tissues known as 'paper for honourable act' ) is still in the folds of her kimono. She is holding an open fan, either to cover her and her lover's faces from an unsolicited witness or to bring some fresh air to their joined lips. The pair just started their sexual intercourse.
A scene from medieval times. A courtier in eboshi cap having sex with an aristocratic young woman with a long straight hairstyle (suihatsu).
Completely naked couple in the moment of ejaculation. Lavish garments with paulownia leaves on a yellow background counterbalance the white bodies on red bedding. The form of a woman's cheeks is telling, but I don't know about what. Maybe her advanced age?
The pose of the couple and the overall composition are similar to that of the previous sheet. Though the lovers are dressed, and the woman's hairdo is well kept. The male looks older and the woman - younger.
A man takes a young maid from behind. She clenches the sleeve of her kimono in her teeth; it's either the moment of penetration (beginning of intercourse) or of her orgasm (the end of it).
This seems to be a forced intercourse between a lackey with extensive bodily hair and a young maid from the same household.
This design is very much like the other one presented below, which is described at Japanese Erotic Fantasies on page 136 (pl. 43b) as follows: "The viewer peers through a mosquito net to see a child fast asleep, while his mother or wet-nurse moves towards her partner. On our print there is no child; instead of a sleeping baby, there is a roll of onkotogami. Fewer objects make the overall image concise, almost laconic in comparison with the Ehon hana fubuki (1802) design:
A young couple in a moment of true love. He is listening to the beating of her heart.
This is a moment of true love between an old monk and a young samurai. The latter even did not take of his socks (tabi).
From Japanese Erotic Fantasies: "Boats played a crucial role in the workings of Yoshiwara, as they were the primary means of transport to the district. During the hot summer months, trips on pleasure boats were also a favourite pastime. Sex aboard a boat is a recurrent theme in shunga".
The last print that I am currently lacking and hunting for:
I know where it is, but I cannot reach it... yet. 
"...The play Yoshitsune Koshigoe-jo was originally written for the puppet theatre (Bunraku) and staged for the first time in the 7th lunar month of 1754 in Ôsaka at the Toyotakeza. It was a revision of two early plays, Namiki Sōsuke's Nanbantetsu Gotō no Menuki (1735) and Yoshitsune Shin Fukumijō (1744). The title, which suggested that the play focused on Minamoto no Yoshitsune, was in fact dealing with the siege of the Ōsaka Castle, led by Tokugawa Ieyasu to destroy the Toyotomi clan in 1614 and 1615. This play was quickly forbidden because of the 4th act in which Gotobei's wife fired a gun at Yoritomo (this was of course interpreted as an attack on the Shogunate). Yoshitsune Koshigoe-jo was revised in 1770 by Toyotake Ōritsu, who completely rewrote the 4th act for a puppet production at the Kitahorieza in Ōsaka". Yoshitsune Koshigoe-jo was staged for the first time in Edo, at the Ichimuraza on the 9th lunar month of 1790, and is still performed.
Gotobei [五斗兵衛] (Gotohei or Gotobē), one of Yoshitsune’s loyal retainers, is forced to choose between his son’s life or his loyalty to Yoshitsune. Nishikidō brothers, who do not want Gotobei to become Yoshitsune's chief strategist, forced him to drink sake and get asleep. To prove Gotobei's military abilities, Izumi no Saburō fires a gun next to Gotobei's ear, and "he jumps up immediately, in full possession of his senses, ready to repulse any enemy". See: [
