I can't handle when they take FOREVER. When its getting near the 15-20 minute mark of giving head i just give up for real. I think hes just playing with me, and making himself NOT COME.
But sloppy, wet, everything you don't find attractive they love. haah
Something i've learnt to do over time is how to guarantee my bf finishes everytime.. but that might just be him,
What I do is start of by teasing him with my tongue, and slowly get full on BUT I almost always use my hand at the same time, double trouble! The reason I do this is because as he gets closer and closer, my hands do all the work, I move faster with my hands and my mouth does so little work towards the end of it, no jaw lock.
