Giving Straight Boy Johnny Head

This time straight boy Johnny stands up and I make him fuck my mouth with his huge dick, and he thrusts his hips like he's slamming a bitch. I can tell he's trying to make it last, but when I start massaging and tugging on his balls, he can't hold it any longer and explodes a massive load all over my face and up over my shoulder. That one sent shivers up his spine.
