At first, the two boys didn't mind Jasper's presence while they made love but then Jasper started getting more intimate and Carl felt uncomfortable about that. "Jasper stop. We might need to tie the horse up."
Eric said, "Naw, it's Jared. I'm surprised he wants in here but he won't bite us."
In reality, Jasper might have bitten, not hard, just a playful, flirting nibble which would have hurt the boys because Jasper didn't know how powerful his jaws were, evolved for chewing tough, fibrous grass. But in the back of Jasper's mind, he did have Jared's idea that horses shouldn't bite people.
Instead, Jasper was more interested in sniffing and licking the boys. When Jasper licked Carl's cock, Carl freaked. "No, Jasper. That's wrong."
Carl backed away from Eric and Jasper. Jasper liked the taste of cock and started licking Eric's cock.
Eric said, "Whoa Jared, I didn't know you were so kinky." Eric scratched behind Jasper's ears.
Carl said, "That's Jasper the horse. Don't you remember what Mr. Marshall said? When Jared becomes a horse, the Jasper mind takes over and Jared really isn't there anymore."
Eric said, "Jared is still there. He understands human speech."
Carl said, "He's barely there. Jasper may be able to access Jared's knowledge but it's Jasper's personality and behavior. Jared has a girlfriend and wouldn't lick your balls."
Eric said, "You're just jealous that Jared isn't licking your balls."
Carl used a stick to retrieve the amulet and Jared's blanket. He turned Jasper back into Jared but the body transformed faster than the mind. It was still Jasper's mind in Jared's body licking Eric's cock. Eric shot his load and Jasper in Jared's body swallowed.
Jasper in Jared's body stood up and his hard cock brushed Eric's cock. Jasper in Jared's body rubbed his cock all over Eric. Eric kissed Jasper in Jared's body.
Then just as Jasper in Jared's body shot cum between the two boys, Jared finally woke up and took control of his own body. He immediately freaked out about having just cheated on Rachel by having sex with Eric.
