Ask Trish to give you a quick handjob while you watch Sammy and Anna going at it

As Sammy face fucks Anna at the end of the alleyway you unzip your fly and pull out your erect cock, stroking it urgently. Trish snorts in disgust at your actions.

"Can you do this for me please Trish?" you ask her, pausing your masturbation.

"What?" she asks in bewilderment.

"Look, I have to keep an eye on Anna and Sammy. I don't have time to play with myself."

"Okay, whatever," Trish says with a resigned sigh and moves up beside you. She reaches around and grabs your erection with her soft hand. You moan as she starts to rapidly tug on the hard shaft, skillfully matching her strokes with Sammy's thrusts in Anna's mouth.

"That's better," you murmur as Sammy continues to use Anna's mouth and Trish's fist is a blur over your cock. You absently reach sideways and squeeze Trish's right breast through her clothing, never taking your eyes off Sammy and Anna.

Just then Sammy stops pumping and holds Anna's face to his crotch. You can see him tensing and know that he is cumming in her mouth. You are close yourself.
