He joins them

Justin decided that he couldn't wait any longer and walked to his sister. Abby saw him coming and immediately grabbed his dick and wrapped her mouth around it, before then sucking his entire length like a **** slut. Her mother spat on her cheek and pushed her head farther onto Justin's pelvis while she spanked her ass multiple times, calling her degrading names all the while :

"**** harder, you fucking cunt ! Drool all over his cock like the dumb slut you are !"

Abby gagged and coughed as she tried to fit the dick inside her mouth, her mother's insults and the spanking she was giving only making her pussy even wetter. After a minute, Justin already couldn't hold it anymore and came inside Abby's throat. Hard. Warm cum exploded out of her mouth, and none of them could believe how much there was. When Abby moved her head back, not only was her lips connected to his cock with several thick strings of spit and semen, but her mouth was completely overflowing with cum.

Macey got up above her and looked inside her open mouth. Abby gargled all the cum in it, some falling down her chin and cheeks on her neck, collarbone and boobs. Macey used her fingers to scoop some of the white liquid and brought them up to her face, observing with lustful curiosity how it fell back on her daughter's face. She then eagerly sucked the cum off her fingers and deeply kissed Abby, both women drinking all the cum.

Meanwhile, Justin decided he wanted to play with his sexy mother's body and went next to her. He grabbed one of her boob with one hand and her ass with the other. He squeezed them hard as he then started to kiss her neck. Macey turned her head to face him and kissed him as well, while Abby was constantly drooling over her tits and belly, spreading the spit frantically all over them.

Not long after, Macey suddenly pushed her son on the ground. She crawled above him until their faces were inches appart from each other. Abby joined her, smiling excitedly as both women were thinking about what they could do with him.
