What kind of timeline are we talking about?
- Immediately after I cum and there's still a puddle in her mouth? No.
- 10 minutes after I've finished my duty and her mouth is empty? Yes.
- Any point beyond that, unless enough time has lapsed in order for another dosage of semen to be inserted in said mouth? Yes.
Think of it this way...most guys love it when a girl kisses them after they've eaten her out. Maybe it turns them on just the same way if you kiss them after they've gobbled your weiner.
