"Cum so much inside that it doesn't overflow even after I pull it out." This is a good example of what can happen when you hold yourself back in your normal, serious job and let your pent-up desires surface. Just being there makes her exude an aura of wanting to do it, and when a man sits next to her, she fidgets as if she can't hold back. When I told her it was okay to do it, she couldn't wait any longer and started sucking his dick, shaking her hips until she squeezed out all the semen.
