Purple Kiss, part 3

Beth stepped behind Amber while Heather stood in front of her. I watched as Amber began sucking Heather's dick, then looked back at Beth. Beth lowered herself and dipped her cock into my mouth. I began sucking it, but she quickly pulled out and raised up to rub it on Amber's asshole. She repeated this several more times, each time getting a little further into my mouth, and a little further inside Amber's ass.
I gagged as she slid her entire cock into my throat. My eyes began watering as she held it there with her balls resting over my eyes. I gasped for breath when she finally pulled out. A large string of thick saliva fell across my face and into my hair.
“Now close your mouth and keep it shut,” Beth said.
I closed my mouth and watched anxiously as she slid her entire cock inside Amber's ass. A large stream of precum spilled out of Amber's dick and landed across my lips as Beth got all the way in and their balls touched.
Heather and Beth began fucking Amber from both ends while I lay beneath and watched. Precum continued leaking out of Amber's cock in great quantities and pooling onto my closed lips. I felt her nectar rolling down into the creases of my mouth and wanted to lick my lips so bad, but I remembered what Tiffany said about keeping the girls happy. So I did what Beth had said and kept my mouth shut as Amber's precum coated my face.
Heather and Beth fucked her rapidly, and soon Amber screamed, grabbing onto my legs for support. A full load of sticky cum shot out of her cock and onto my face as Beth fucked her as fast as she could. Amber went limp, collapsing onto me with her cock and balls resting on my cum covered face.
Beth went down with her and got a few more strokes in before pulling out and cumming all over Amber's balls. Her cum ran down Amber's balls and gathered on my forehead. Amber began slowly sliding her half limp cock and cum covered balls around, smearing the cum around until it completely coated my face. She raised her hips and repositioned herself so that her glazed balls were above my mouth. I opened wide and she lowered them into my mouth. I sucked the sweet cum off of them in ecstasy while Heather continued fucking Amber's mouth.
