Sitronmelde - no, no, no, you can't oblige! If you go through the trouble of saving a load for 5-7 days and even edge every day you have to show that water show. She'll never truly appreciate it inside.
I was in this exact position in my single days. I was fucking bare-bone and of course, she moaned, "Cum inside me, I'm on the pill." I had only been saving for two days, but I did hours of edging each of those two nights. Hearing her say, "Cum inside me," turned me on so much that I pretty much started orgasming right there, but not before I grunted, "No, you gotta see this ..." i pulled out, jetted maybe 7 thick gloppy roped all over her abdomen, torso, neck and a little on her chin. Later she said she had wanted me to cum inside her because she figured it would be an easier clean-up, but after seeing my cumshot and feeling it jet all over her she agreed she wouldn't have wanted to miss it. Then she said something like, "i never thought of myself as a cumfreak, but I guess now I am."
