my wife had me do the sucking and because my mouth is big and my neck strong i can service a big cock and do it for a long time also the guy can face fuck me and get his cock all the way in and often try to get his balls in as well. Good cocksucking also involves knowing when to slow down or when to lick behind the balls and it gives powerful orgasms with a resulting load of cum. I do not like the taste of cum but it feels good for the cock to have it swallowed
