This doesn't look like it belongs to the Awkward Sex pool by both definition.
1: Physically Awkward: Images depicting a person or persons having sex in a strange way. The position they are in just looks uncomfortable or the place they are in is very strange and unfitting.
I mean, they're in adults goods shop. Is it really strange to have sex there, given some shops even has special rooms to 'try' the merchandise?
2: Socially Awkward: When a character says or does something that makes things awkward or would be awkward to hear or see if you were in that situation, like the woman saying to the guy "Yours is the 30th largest I've ever had!", or someone falling asleep during sex.
In context of 'this onahole doesn't feel better than normal pussy' it's also not socially awkward either.
