Champagne Glass

Had a mad idea for a dirty outing with my naughty wife.
Maybe take her to a local adult video place and have two or three horny older men take turns in her mouth along with me. When anyone feels they're going to cum, they'd pull out of her lips and cum into a plastic champagne glass that we'd have brought along.
Once there's like four loads in the glass, my dirty wife will look up at the men with our spent dicks and smile as she slowly drinks all the cum, maybe spilling some down her chin and dripping onto her titties.
She's a champion cocksucker and cumlover so she's hot to do it.
Besides she always does what she's told anyway.
