It shot into her mouth.

As the cum boiled deep in my balls I knew I couldn't last much longer. Lorraine and Judith both moved their pussies near to Debbie's head and she reached over to lap at them in turn, as they panted in excitement. They were both rubbing their clits hard and then Judith moved her hand inside Lorraine's hole. She looked down at my huge cock slipping in between Debbie's tits and said: "I want you both to cum on her face."

Lorraine and I groaned in excitement at the idea and I sped up my pumping. Judith angled her fingers up in her younger sister's pussy to stroke the g-spot and immediately the blonde girl screamed at the top of her voice: "Oh! Fuck! Yes! I'm cumming!" The first squirt from her pussy hit Debbie's mouth.

Her eighteen year old cousin opened her mouth in surprise just as I released my first spurt of cum. It shot into her mouth and was joined there by more of Judith's girl juice. Together we shouted out in elation as we sprayed our juices all over the pretty girl's face and neck and chest. I couldn't believe how much cum I had left in my balls.

It kept spurting out in stringy white wads and mingling with Lorraine's musky liquid until the writhing, panting teenager beneath us was drenched, and the only sound was her murmuring: "Oh, yes. More. Give me more cum. Oh yes. More." Finally the cum dried up and I collapsed, utterly exhausted. As I drifted away into unconsciousness, my final image was of my cum, mingled with Lorraine’s, running over Debbie's perfect tits and my beautiful dark neighbour Judith leaning over them and starting to lick it all off. I fell asleep with a smile on my face.
