I love to tempt my fwb in that position when my cock start leaking and is about to explode. I pull out, look at her with a grin on my face and say "I'm about to cum, should I just stay here?" while having the tip rubbing her hole. Obviously the temptation is too big for her and sure enough, she impales herself on me so I can cum deep inside her. I grab her waist, keep her down on it while slowly see sawing her, she sure loves the babymaking training...
