Ty ignores the begging mother's plea, instead he lines the tip of his horsecock between the 10 year old's ass cheeks and prods the entrance.
"A-aahh mommy! Mommy he wants to stick it in me!" The kid's mine turned into nothing but lust, hands going for the stallion's thick shaft to urge him to push deeper. "F-FUCK ME, MR HORSE!!"
"NNNEEEIIIGGGHHH!!!" Ty grabs the boys legs and thrust hard, plowing half his horse meat into his asshole as pre-cum lubes it up to make the friction less noticeable. The mother watches with jealousy and envy in her eyes, but moans away and coo's encouragements at her child, wanting to make sure he is receiving the best pleasure in his life. "AAAaAHH BOY ASS FEELS SO GOOD!" Ty snorts and neighs, keeping his motion at steady but hard thrusts. It wouldn't take long for the horse's orgasm to build up, pulling out of the boy's entrance to start stroking his own cock. "Nnnngg open your mouth.." The boy eagerly did as he was told, lapping his tongue out like a common slut.
"Oh pleasegiveittome..giveittome..pleaseIwantit.."The boy whispers and begs, his mother crying out in pleasure as she has her own orgasm.
"FUCKING TAKE IIIIT!!" Ty neighs and shoots his seed all over the rancher's son, coating the boy with rope after rope of thick horse cum. Once completely covering the boy head to toe in horse jizz, Ty aims his cock at the mother and shoots off a load on her as well. The mind-broken humans licked and slurped the horse cum up, even licking and kissing it off each other as Ty watches with the most amusement. "I like you boy..I think I'll keep you." Ty grins at the rancher's son, almost paying no attention to his mother at this point.
