Cum in Millie's mouth

I decide to do everything I can to hold back and cum in Millie's mouth instead of Patti's mouth. The strength of the suction of Patti's mouth on my dick is immensely pleasurable, but I manage to keep from cuming.

"Time!" I call out. My eyes are closed, but I feel Patti's mouth being replaced by Millie's mouth. Millie starts sucking my dick with her mouth only, going halfway down my shaft, then twisting her mouth as she moves her mouth up the shaft.

Within a few seconds I release my cum into Millie's mouth, and when she feels her mouth filling with cum she starts to make little shrieks of joy. She knows she has won the contest.

I open my eyes to look down at Millie sucking the last few drops of cum out of my cock. When she is certain there is no more cum to get out of it she stands up and looks over at Patti. Patti has sat down on a chair, and she looks almost in shock at having lost the contest and is sitting there just staring at Millie with her mouth open.

Millie practically does a little victory dance over to Patti, she puts her hand on Patti's forehead, bends Patti's head backwards, and spits the cum into Patti's mouth. Patti is so surprised by this rapid move that Millie actually gets all the cum into Patti's mouth. Patti looks absolutely disgusted, and spits the cum out into an empty wine glass next to her.

Millie looks at Patti with a triumphant look and says:

"What, you don't like the taste of victory?"

Patti just stares at Millie, who takes the glass full of cum and walks over to me and sits in my lap. She takes a sip of my cum from the glass, looks at Patti, then says:

"Get ready to be fucked in the ass big sister!"

With that, she makes a toasting gesture towards Patti, and drinks all the cum left in the wine glass.

"I need another drink." Patti says and tops up her wine glass.
