She wanted to tell Susan to shut up, to stop saying those things, but her voice seemed frozen. She twisted her rounded ass into the cushions of the couch, trying hard not to let Susan become aware of her feelings.

But Susan was still talking.

"His cock would get so hard in my mouth, and when he came, it was a real gush!" she said softly, sniffing now and then. "I didn't mind at all. It tasted so good to me. I didn't know about his girlfriends for a long time. Then, one night when he came home, I was in the mood, and I jerked his pants down as soon as he closed the door, and started sucking his cock. At first I didn't notice anything, then I realized his cock had a different taste on it. When I realized was the same taste after he fucked me, I knew then he had been out there fucking one of those tight-assed little cunts of his."

Marcy shuddered, thinking what a shock it must have been to Susan to taste another girl's cunt on his cock. She, herself, had no idea what it would taste like, but she could understand Susan's shock.

"I can imagine how sick that made you," Marcy whispered at the top of the honey-blonde hair.

"Oh, no!" Susan blubbered. "It didn't make me sick. It made me very mad at first, but then… oh, God, Marcy! I got so excited, knowing I was tasting another girl's cunt on his cock, I almost swallowed his prick completely! I started to come and didn't stop until he shot his big load of fuck-juice down my throat!"

The sound that came out of Marcy was more a squeal than a gasp.

"Something about tasting a pussy on his cock excited me," Susan said, running her hot palm along Marcy's thigh, from her knee to halfway up. Her movement was dragging the hem of Marcy's skirt past her knee, and Marcy stared at her hand, her eyes turning glassy. "I don't know why, but tasting that little cunt's juices on his cock sent me into orbit, Marcy!"
