Samantha's cunt

You get on the bed behind them both. When you pull their legs apart, they groan. Their hips grind into each other, as you crawl closer. You lean over the two sisters and look Alicia in the eye. Her face is a mask of pleasure.

Samantha turns her head and says, "Are you going to fuck me now? I'd love to have that cock of yours inside me."

"Yes, just keep kissing your sister" you instruct her.

You guide your stiff cock toward her cunt and slip the head in. You reach between the two girls, firmly grabbing Samantha's hips, and thrust hard and pull her toward you. Alicia's sister shrieks as you penetrate her in one stroke. You've just come, so you pound away at her at a maddeningly fast rate. Your thrusts must be pushing her groin into Alicia's, because the skater girl starts panting and whimpering.

"Fuck! That feels good!" Samantha says, panting hard.

The two sisters shift under you and Alicia groans, "Yes! Yes! Fuck me with those fingers, Sam!" You just keep pounding into Samantha. Her cunt is hot and wet, and your cock slips in and out quickly and easily, generating lots of heat and pleasure.
