"They just did that to make their cocks slippery, Stacy. With their tools coated with cunt juice they don't have to take time to go get Vaseline or some other lubricant. Saliva works okay, too, of course!"

The women had stopped eating each other and the men had shoved their pricks into the pussies from the rear. They'd only made a few thrusts before withdrawing, however, and their cocks were wetly glistening. Each man placed the blunt end of his thrusting cock against a puckered anal opening and the bed was situated in such a way that Stacy could see each big knob pop past a tight elastic ring.

Stacy mentally flinched in sympathy with the two women. She could see the expressions of pain on their faces, and she'd experimented enough with herself to know that the swollen glans lodged in the assholes just about had to hurt. In her excitement while masturbating she'd often gotten carried away with passion and shoved a finger up her own ass. She'd read that the entire anal region was considered to be an erogenous zone and it was certainly true with her.

But a finger wasn't like a big hard cock! She'd gotten used to her finger, or her asshole had, and it felt good when she occasionally finger-fucked herself there while stimulating her cunt and clit, but she didn't think she'd want to try anything bigger than her finger. Many women liked to be sodomized, though – as did some men – and the pained expressions on each woman's face was turning into one of bliss.

Both cocks had slowly disappeared and the men had started slow and steady in and almost out thrusts. They were pumping in the same tempo, seemingly on purpose, and the women were hunching along with the pistoning pricks. Then the women resumed the intimate oral act that'd been interrupted, really burrowing their faces into each other's crotches, and the four moved in unison for two or three minutes.

Suddenly one man began to pump erratically, his firm-looking buttocks moving in short jerks instead of in the smooth rhythm that Stacy had found so fascinating. The jerky motions made her even more excited. Because she knew that his sperm was shooting out of his cock into the woman's asshole. Or into her bowels.
