A curious teenage girlfriend decides to give her boyfriend a special birthday present - her first blowjob. She takes his cock in her mouth, her inexperience evident as she struggles to take it all in. He coaches her, encouraging her to go deeper, and she obliges, her enthusiasm making up for her lack of skill. She gags on his length, tears streaming down her face, but she doesn't stop. He fucks her mouth, his hips moving in short, sharp thrusts, until he can't hold back any longer. He pulls out and cums in her mouth, she swallows it all, proud of herself for making him feel so good.
