Because they're not related by blood, a stepmother and son become aroused by the body of a relative in name only, and begin a relationship. The lusty stepmother ignores her husband's useless, rough dick and instead uses her young son's strong, hard cock as a "tool" to release her sexual desires. When her body gets hot, she immediately starts sucking on her son's cock, squeezing it deep inside her vagina and thrusting her hips in an extreme way to induce a creampie.
