The son, having grasped his stepmother's weakness, proposed cunnilingus as a condition for exchange. Unable to refuse, she spread her legs, and he began to lick her vagina greedily. Then, he asked, "Sit on my face," putting her into a facial riding position! He frantically sucked at her genitals with his tongue, causing her hips to move on their own, and she blushed as she came. Unable to hold back, the stepmother took his penis in her mouth and inserted it herself... leading to an incestuous taboo！！
