Denise paid no attention, but began slowly withdrawing the dildo until it was
halfway out. Then she slowly thrust forward again, her face a study in
concentration. She was fucking Ruth, slowly penetrating her with the long, thick
dildo, then slowly withdrawing halfway and repeating the process. The dildo slid
easily on a generous coating of pussy juice. Ruth put her hands under her knees
and pulled her widespread legs up to her chest, tilting her pussy to meet the
invading phallus.

"UUUUUuuuuuuuuunnnnnnNNNHHHHH," Ruth groaned at the next penetration, and Denise
stopped momentarily.

"Does this feel okay?" she asked, and Ruth quickly nodded her head, 'Yes,' while
she stared longingly at Denise's tits, bobbing just out of reach above her.

Denise began to speed her thrusts and I put my mouth against her ear.

"Shift your weight forward to rub her clit more," I whispered, and she did,
prompting another long moan from Ruth, "UuuuuuuuuuuunnnnNNNNNNHHHHHHH!"

Denise was concentrating intently, looking down to where her hips met Ruth's,
connected by the gleaming pink shaft. Her pleasure rising in steady waves, Ruth
began encouraging her lover in a low, urgent whisper.

"Yes ... sweetheart! Fuck me with that thing! Oh ... oh ... oh ... yessss,
babyyyyyy! ... That feels so gooood! ... So deeeeep! ... So haaaard! Yes! Yes!
YeeesssssSSS!!! Harder! HARDER!

Denise had mastered the dildo strapped to her crotch and was fucking with ease
now, ending each thrust with a small grunt. I watched her muscular buttocks flex
each time she pushed her artificial dick into Ruth's waiting pussy. Sweat
glistened on her back and made short wisps of black hair cling to her neck. She
was breathing deep and steady, like a runner pacing herself in a race.

After several minutes of this treatment, Ruth gradually fell silent. Her eyes
screwed shut and her breathing changed to quick, shallow pants. She strained to
hold her legs up and open, with her forearms hooked under her knees. Then she
gave a long, high-pitched whimper and exploded, crying out wildly and thrusting
herself up at Denise.

"GAAAAAAAAAGGGGHHHHHH!" Ruth shouted. "OH, FUUUUUUUUCCCCCCKKKKK! FUCK! FUCK! FUCK
ME! FUCK ME! FUCK MMEEEEEEEEEE!!!"

Her head slammed back onto the bed, her back arched and her hips began thrusting
urgently upward to meet Denise's descending shaft.

"UNNNHH! UNNNHH! UNNNHH! UNNNNNNNNNNNNHHHHHH!!! she moaned. "Oh, SWEETHEART! Oh,
SWEETIE! OH, YESSSSSSSSSS!!!

I thought Ruth's orgasm would never end. She moaned and cursed and bucked and
shuddered until Denise had to fall forward, hugging Ruth tightly to stay on top.
Ruth's hands were all over Denise, now gripping her ass-cheeks, now raking her
back. Denise gave up thrusting and just hung on, her rubber penis completely
buried inside her lover.

Finally Ruth was spent, motionless, lying still under Denise, but still breathing
deep, harsh gulps of air. Denise raised head and looked at me with wonder.

"That was AMAZING!" she exclaimed. "Doing that to her, I felt so SEXY and so
POWERFUL at the same time! What a RUSH!"

I leaned over to Denise for a long, lingering kiss, tasting sweat on her lips.

"It's a kick," I said, "and you did a great job. You already know more about
satisfying a woman than half the guys on the planet."

Denise gazed thoughtfully down at Ruth's face, lying slack and serene a few
inches below her own.

"It's not exactly easy, but it's sure worth the effort," she mused. "I could FEEL
her cumming with every ounce of her body."

She laid her head on Ruth's shoulder, gently kissing and caressing her with a
tender expression on her face. I slid one arm under Ruth's neck and the other
across Denise's shoulders, hugging them to me. We rested like that for a long
time (I may have dozed a little) until Ruth suddenly moved and giggled, "I never
want to move again, but if I don't, I'm afraid my legs will start to cramp. If
THAT happens, you guys will be carrying me to the emergency room to have this
thing surgically removed!"

We all laughed at that and Denise began slowly, gingerly to remove herself from
Ruth's embrace -- and her pussy. The first few inches of dildo came out slowly,
reluctantly, Ruth's coarse pubes and inner labia clinging wetly to the pink
shaft. The last couple of inches popped out in a rush, leaving the mouth of
Ruth's pussy gaping open for a second. Denise knelt there, stroking the dildo
dangling between her legs, and Ruth reached down to rub her crotch.

"My pussy is going to be as sore as my ass!" she declared, then she blushed.

Denise looked at me with arched eyebrows.

"I fucked Ruth's butt this afternoon," I admitted. "She was great!"

"You guys really HAVE covered a lot of ground," Denise laughed. "Here, help me
with these straps."
