Satsuki Uchiha (External and External ) was defeated by Deidara and turned into his sex slave with a very high quality aphrodisiac.
Satsuki is riding Deidara reverse cowgirl style while having a very flushed ahegao face and her pussy sopping wet, while deidara is siting up with his hands on her breasts so his mouths can tease her nipples, whispering into her ear about how she is really an Uchiha slut who loves being fucked by his cock, to which the female Uchiha is responding with slutty moans of pleasure and telling Deidara to keep fucking her. The reason why Satsuki submitted to Deidara so easily is because she is very sexually repressed and the Aphrodisiac caused all the bottled up sexual frustration to come out full force.
Also there is a naked Naruko in the background on her knees masturbating to the scene with one hand, while the other is foundling her breasts moaning in pleasure about how hot this is, she is also wearing an ahegao face and has sopping pussy. The reason why Naruko is masurbating instead of helping Satsuki is because Deidara got her with a smoke bomb that contained the same aphrodisiac that he used on Satsuki and Naruko has been suffering from three years of sexual frustration due to not being able to masturbate because of her training trip with Jiraiya along with all that's been happening when she returned to the village.
