Take her doggy style

By now Susan's balls were starting to literally ache from not getting any relief. Pleasuring Sheila had proven to be more satisfying than she ever would have imagined, but she had to cum soon. And she wanted this poor little house wife married to that small cocked asshole to get to experience Mike.

Susan gently took the woman's hip in her hand and urged her to roll over, which she quickly did. Sheila looked back over her shoulder nervously.

"I've never felt anything like this," she said. "My husband took my virginity on our wedding night and I've never been with another man. He doesn't do any of this stuff. He just puts his cock in, humps me for two minutes and cums. He's never given me an orgasm."

"That's just not fair," Susan said, but all her mind could focus on was putting her own cock in. "Happy I could help."

She guided Sheila up onto her knees, then positioned herself behind her. Susan aimed her cock at the woman's dripping pussy and pushed forward. It barely expanded enough to accept the head, which was enough to make Sheila start cumming again.

"Oh fuck, you're right," she said.

As gently as possible she pushed harder. On the midst of her moans of pleasure, Susan thought she heard a few groans of pain, but it was all going to be worth it. It might ruin Sheila's pussy forever for her husband's tiny penis, but it was going to be worth it.

It took several minutes and lots of pulling out and going back in to get her cock lubricated, but finally Susan managed to get herself all the way into the woman's tight pussy. The entire time Sheila was almost shaking from what turned out to be one long, continuous orgasm.

"I... can't...take...much...more," Sheila moaned.

"You don't have to."

Finally she started fucking Sheila. As she pounded in and out of her, absently she wondered if John's ass would be this tight, or of Diego had ruined that "pussy" for her. That made her a little angry, and she fucked Sheila harder.

"Oh...fucking...God!" the woman moaned, and suddenly her already tight pussy clamped down tight.

Susan couldn't control it. Her balls exploded deep inside of Sheila's pussy, which started contracting again, milking her cock dry.

When she was completely spent, she pulled out. Sheila collapsed face down on the bed and seemed to immediately pass out. Susan lay down next to her and wrapped her arms around the woman. They lay there silently for a very long time.
