Joe saw the oppurtunity and seized it. He mounted his friend and readied his penis for insertion. His front legs wrapped themselves around her mid section. His cock was rather hard right now, too. Normally, its 6 inches and it extended to 10 inches. It throbbed and pulsed wanting to spray this load into Karyn so bad.
"Do it! I'll die from this uncontrollable lust!" She said. Joe obliged her and started thrusting into her vagina. It felt so good. Joe felt like his horse penis wouldn't fit but he could shove at least half of it in. He loved Centaur sex. It felt so good, especially with Karyn. He kept thrusting and he blew his load all over the walls of her vagina. He silently wished for her not to get pregnant. He wasn't ready for babies, just yet.
"Uhhhh.... Yes! Yes! Yes!" She moaned. Joe looked around and no one even noticed their sex parade. Apparently, PDA's (Public Displays of Affection) including sex were normal. You dismounted your new mate aftervthe last of your load and watched the game, for the rest of the time. Your penis still dripped with white cum, you still being horny from the glorious centaur sex.
