Casey frots with you while you get fucked

Before Sara pulls out of you, Casey mounts you in front of her and starts rubbing her cock against yours. Her 8 down-curved inches feel significantly bigger than your cock, which excites you. She grabs your cocks and pushes them together, thrusting against you firmly. You bleat into Ashanti's undercarriage as Casey's dominance causes you to cum against her. She lets you cum on her cock, spreading your sperm up and down her hard shaft. Then she takes Sara's place at your ass and slides right in, lubed by your own jizz. You shudder as your orgasm subsides. The four t-girls take turns like this for about 20 minutes, exploring your rectum and filling your mouth constantly, but stopping before they cum. They coordinate so that they're all ready to blow at the same time...
