Lily put her tongue in her mouth and closed it when she saw that her sister wanted his cock the most. "You can go for Diana first, Rex... I can wait."
"N-No... we can do it together!" Diana said while looking at Lily.
"Nah, you go first..." Lily smiled with both her eyes closed.
"Lily... thank you so much, little sister."
Diana did what she was told again and opened her mouth wide, stuck out her tongue, and got ready to get whatever Rex had planned for her. She could feel his huge cock throbbing and pulsing against her chin, and she could feel the heat of his heavy balls hitting her spit-slicked tits with every thrust.
She knew he was close and could feel the huge load about to explode. And she wanted it more than anything else.
She wanted to taste him and feel his thick, strong seed filling her mouth, throat, and stomach. She wanted him to mark her, claim her, and own her in the most basic way.
"Don't worry, Lily, you'll get some too." Rex patted her head.
