Bend over in front of her

I slowly moved myself into a standing position in front of her as she sat down on the couch. She reached up and parted my ass cheeks. I never thought I'd be turned on by having a girl looking at my asshole.

"This is gonna be so much fun," she giggled. "If you're good...maybe we can by me a strapon to go with this. Would you like that?"

"Maybe," I said, not wanting to sound too eager.

She slid the big black cock down my asscrock until she reached my asshole. Then I felt a warm sensation as she squirted a bottle of lube on the dildo and into my crack.

"I'm so glad Amy introduced us," Kate said as she began pressing the head of her toy into me. I moaned as my asshole stretched to accept it. It was much less painful with lube. "All these years, I had no idea you were into guys until she told me. As you can tell, thats my dirty little secret. I think bisexual guys are so hot."

I was wondered why Amy would have said something like that before I even knew it when Kate slid the dildo home. I almost screamed in pleasure. It was larger than David had been and my ass had to stretch to new limits, but it felt good.

"Bi bottoms are especially hot," she continued as she fucked my ass with the big black dildo. "Any guy can be a top, even a straight one. Being a top is just about getting off. I mean, an asshole is an asshole, whether its mine or yours, right? Its gonna feel the same to the top."

As she continued to fuck my ass, she reached down with her other hand and started stroking my balls.

"But a bottom! I know how it feels to get fucked in the ass. You have to submit yourself totally to someone to let them shove a cock up your ass. That is fucking beautiful."

I moaned again.

"I mean, this is hot," she continued, slowly moving her hand to start stroking my cock. "I plan to do this a lot. But this is just a toy. Its like a handjob compared to a pussy. But I want to watch another man fuck you...hard. I want to see my boyfriend get turned into someones bitch. When he's done, I'll fuck your brains out."

My cock suddenly exploded, spraying cum all over my parent's coffee table.
