Ty lunges in and starts forcefully making out with Dustin, pushing his tongue into his foster brother's mouth. Dustin gasp and moans in protest, his arms being pinned by Ty with unknown strength preventing the older teen to move. Dustin eyes grew really wide when they caught a figure standing at the doorway. A shock look ran across June's face when seeing her two children naked and missing one another. Dustin was sure she would freak out and give Ty the biggest ass-chewing of his life, but instead her face relaxed with hands moving between her legs.
"Ty and Dustin..!" June weakly calls out, closing the door behind her as she digs her hand into her pants. "You two are so cute doing that! So sexy too..keep going.."
"M-mom!?" Dustin manages to break the kiss, panting a bit more heavier as the pleasurable feeling of their cocks rub against each other. At this point his body was no longer fighting to resist Ty's advances, caving in to such erotic behavior. "T-Ty..what happened to mom..?"
"June's fine," Ty licks the side of Dustin's neck, grinding against the older teen. "Undress and get on the bed June. You can play with yourself there." She didn't hesitate after hearing those words, stripping to be completely nude before climbing onto the bed to continue masturbating. "Lets join our mother, Dustin."
Dustin didn't speak up in protest, instead he follows Ty to the bed to gently climb on. In a instant, June spreads her legs wide to show her very wet and hairy pussy.
"Kiss each other some more, and I'll let you fuck mommy~" She coo's at them, fingering herself with three fingers. This time Dustin was the one to pull Ty in for a deep make out, both their hands reaching for each other's cock to stroke it. The sight of her two sons making out with each other quickly sent the mother into a hard orgasm, squirting her juices all over them. Ty breaks the kiss and whispers into Dustin's ear.
"Go and fuck your mother, Dustin." Ty kisses his ear and lets go of him, watching his foster brother scoot over to June. The older teen sticks his cock into his mother's folds, moaning loudly from the extraordinary feeling and proceeds to thrust and hump.
"O-oh mom!" Dustin rubs his face against her breasts, his inner urges of fucking and breeding his own mom were quickly taking over his mind. "Mom you feel so amazing! Your pussy feels amazing!"
"Fuck yes! Fuck me!" June moans back, wrapping her arms and legs around her son as he pounds into her like a horny animal. "Fuck your mommy, Dustin! Oh fuck your cock feels so much better than Mark's!"
Ty watches on for a moment before getting into the action, pouncing on top of Dustin and prods his entrance with the tip of his cock. Dustin was in pure bliss to notice, and probably somewhat welcomed the strange feeling that was taking place behind him. With a loud groan, Ty shoves his whole length into his brother, causing the older teen to moan out in more pleasure than pain. The three family members fucked away for what seemed like an hour but was actually minutes, with all their climaxes quickly approaching. Dustin and June embrace each other with a kiss as her son starts cumming deep into her womb, all while Ty gave a few last thrusts before filling Dustin's asshole with his jizz. They pulled out of one another and cuddle together, their sweaty warm bodies kept the three comfortable and in a stable state of happiness.
