Her boyfriend ejaculates in her face and keeps sucking her dick

Her boyfriend suffers from premature ejaculation and whenever he feels his tongue on the penis he ejaculates without control. The girlfriend has been with him for many months now and instead of getting upset, his ejaculating so fast makes her feel much more excited because she feels that she is the one causing those uncontrollable levels of orgasm. One afternoon the boy asks his girlfriend to perform fellatio to distract him from the boredom, and as soon as he puts his penis in the girl's mouth he feels it coming and does it on top of the girl's face. She enjoys his semen, tastes it and before the penis loses its erection she continues to suck him uncontrollably, with the purpose of having him ejaculate on her again.
