Zoe feels good...

You keep hammering at Zoe's snatch. You know the plan, but Zoe feels so good. She's squeezing and gripping your cock inside her in delicious ways.
You fish around for one of the dildos, and start working Jenna's snatch.
"You getting me ready, baby?" Jenna coos, leaning over to make out with Zoe.
"Yeah...." you keep on pounding. Your sister is making the most adorable little sounds.
"Fuck me, big Jimmy. Oh you don't know how long I've waited for you to fuck me..." she strokes the strapon as if it were her own dick. "Im gonna cum on your big thick dick, James."
Suiting her words, she releases a flood of pussy juice. Jenna shudders as Zoe flails out with a hand to find Jenna's clit.
"Jenna...he's making me cum so hard....!!!! THANK YOU!" Jenna looks like she might be close to a second one herself.
"James...please..." she has a little bit of concern in her voice as she watches your face contort. "...the... the plan."
