just a guy

I finally figured out how to do this! First fuck and then cum in her and then use a big black dildo on her until she cums. Then lick her clean. It should have been long enough for you to get horny again watching her take a BBC while telling her her how much it turns you on, then immediately cleaning her after her "Bull" has finished fucking her. Some cum will transfer to the BBC and you can offer it to her to lick clean. She will love it and it will plant the seeds of future endeavors.

It's easy really. You could do it when you're horny, but not right after you cum. Have her go and find some young guy who will cum in buckets and fill her up for you. She might even use the cum to slicken her fingers to fuck your ass. Telling you that you now have her lover's cum in your ass... do you want more?
