"Jeff honey, are you ready to go?" Jeff's mom asked through the door.
"Um, go where?"
"The farm, oh don't tell me you forgot again!?! We're due down at Mr. Hanson's farm. The last batch of collected semen didn't take, so he wants you to 'personally' deliver it." Jeff's mom said.
Jeff felt his stomach drop, and his cock twitch. He had to have sex with an actual horse? Getting turned on by the smell of a mare's vagina was bad enough. He didn't want to go anywhere near a real one! To his horror, the images of mare vaginas flashing in his mind were increasingly arousing. Some feral part of him DID want to breed. His cock began to stiffen in his pants, and Jeff paled. Frantic to put a stop to things, Jeff started typing. But his efforts were in vain, as his mother finally burst through the door and slammed his laptop screen down. Then grabbed his collar and dragged him out of the house without so much as a chance to see what he had accomplished, or cursed himself with.
Just before he was dragged away kicking and screaming, Jeff had managed to start typing. What he typed he didn't know. But he would soon find out. Climbing into the passenger seat of his mom's mini-van, Jeff dealt with an uncomfortable erection tenting his pants, while he changes began.
