That is how you suck cock. Lots of tongue and lip play. Take that soft tip deep into your throat, let it fills you full of cock, hold it deep. Make it throb and ooze for you. Look into his eyes to share with him that you're a total slut. Continue until he can't take it any more. Let him know you are sucking him because you want, you love, you so need his delicious fuck-juice. Be a beautiful woman and a passion filled slut, his slut. Have him return the favor. Feed him your goo, smear his face with your juice. Kiss.
