Ok, so thanks to this thread, my wife and I tried something new last night. Prior to this "idea", every time I've cum, I always, always, make it a point to cum in her pussy as deeply as possible. It seems more satisfying to me.
Last night, instead of ejaculating deep, I decided to cum shallow... a bit beyond the entrance. When I was done squirting the last drop out, I then plunged deep inside her and start fucking furiously. Unfortunately I can stay hard for about a minute after I ejaculate, but the was the slickest minute I've ever felt my cock. The semen slathering all over my dick and inside her cunt could've almost made me cum again.
So I gotta give you'ze all props for a great thread. Thanks!
