I think both twink boys should share Zilv. He is such a horny daddy and he needs more than one boy to fuck. It is clear both boys enjoy being dominated by him. They behave like slaves when with him, whether it is being deep-throated and gagging on his large cock, licking his balls or fucked in missionary position or from behind etc etc
When you and your young boy are on your knees and is ass is full of your cock. Then he arches his back and leans back and you kiss that is a wonderful moment at least for me. I definitely have to keep it check not to lose it prematurely in his little ass while we kiss.
