It depends on the woman for me, i've had some that were fucking skilled and the eye contact was just another thing they used to get me off and it would work, like there was one, i'd warn her i was about to cum and she'd give me this look that would without fail every time push me over the edge.
On the other hand i had one fuck buddy for a few years, great ass and a tight pussy but she was very vanilla in bed and there was no amount of instruction to improve her blowjob skills and she'd just stare up with a stupid confused look on her face, literally the only time she ever got me off i did 90% of the work jerking off after a painful half hour or so of her sucking, then gave her control again once i was in the home stretch, she didn't want it in her mouth or on her face so i said i'd warn her and she could aim it at her tits, there she goes again with that stupid look, just sucking the top 20% and stroking the other 80%, i gave her warning and she just kept going with that stupid look, i warned her again and still kept going, there was no third warning as i exploded in her mouth and it was a big one, she pulled back taking a few more ropes to the face, she wasn't overly pleased as i tried to hold back laughter but like i told her i warned her twice, she's the one that kept going. After that BJs were just foreplay, i'd grab the back of her head and do my thing for a bit then fuck her
