If someone denies you anal all you have to do is take it from them. It's not rape if you say surprise!
They will enjoy the pleasure so much they will show you their tears of joy
If they cry, use the tears as lubrication or as a punishment use no lube at all.
Guy: Baby, can I stick it in your pooper?
Girl: No because it will hurt.
Guy: I'll be gentle, I'll go slow.
Girl: I said no, I told you to stop asking.
Guy: Oh well......SURPRISE!!
Girl: OMG! , STOP!, NO!
Guy: When you say no, all I hear is, "No don't stop"
Girl: This is rape!
Guy: I said surprise and it's not rape if you say surprise.
