You try Alyson's mouth as well

Leaving Sarah just like she is, with a dribble of your cum leaking from the corner of her mouth, you walk over to Alyson instead and pull her up from the ground by the hair.

Her pretty face and most of her body are smeared with mud, but it's starting to wash away as you hold her up to the pouring rain.

"What...?" She start to ask you, apparantly still dazed after you hit her and also blinded by all the mud and water. When she feels your hard cock sliding in between her open lips she tries to fight back though, even if she's quickly drained by what little strength was left in her.

Soon there's nothing she can do but keep up breathing around your meaty shaft, giving up entirely on trying to resist you.

She's still not much of a help though, and you have to do all the work yourself until you finally find relief all the way deep down her throat. By then she's quite the wreck already, completely subdued by the most vigorous face fuck, and once you're done she drops face down back into the mud.

Meanwhile, Sarah seem to be partially awake again, and you can see her slowly stroking her cunt while she watches you finish with her friend. Kinky...
