At my sister's wedding with her new husband filling my mouth with cum.

I am not able to say no one more time to my sister's new husband. more than once being at home while my sister sleeps we have escaped to the bathroom to get a hand and a quick straw. but even though she just married my sister, i'm looking forward to having her cock in my mouth again and for her to fill me with cum, even at the wedding banquet. i can't stop sucking and licking my lips with pleasure as i keep thinking that this will be the last time. or maybe not?.
