Cum. It's cum.

"FILLING...YOU...UP" she says as she thrusts roughly one last time hilting her love stick as far inside you as it can go. You gasp as the first spurt of cum floods your bowels. True to her word, it feels like she's invaded your stomach and you feel like the cum is dropping right in there.

She finally stops cumming and pulls her cock out, again her cum instantly looks for an exit out of your now gaping asshole.

"As always, thanks for the fuck. Come back again" as she blows you a kiss and puts her clothes back on.
