Her lips were wrapped around the base of my dick, her tongue darting out to lick my balls. I grabbed her hair and started fucking her face like there was no tomorrow, feeling my hardness slide through her mouth and down her throat.
Pippa lift up her head, taking my dick out of her mouth and started to stroke it. "God, I want someone to fuck me whilst I suck your dick." She reached down and shoved her vibrator back into her soaking wet pussy, started moaning, and went back to sucking me off.
I felt myself get closer and closer to exploding down her throat, when I heard the door bell ring. I was tempted to ignore it and shoot my load when I remember that a friend was dropping around some DVDs before he headed off on holiday.
It occurred to me that Pippa hadn't heard the door bell, given how hard she was working her vibrator and my dick. "Do you really want to be fucked at both ends?"
She moaned. "Oh yes, I want to be completely filled." Just then the door bell rang again, and this time she heard it.
I jumped up "Stay there. If that vibrator isn't still in you when I get back the only place my dick will go this weekend is your ass." I threw on some jeans and a T-shirt and headed down the hall and opened the door. Sure enough, it was Mark.
"Howdy. How you going?" I asked, still slightly out of breath.
Mark grinned. "Good, but not as good as you. You can hear Pippa down the driveway. I was about to leave this stuff and head off."
Pippa has had a thing for Mark for years, which is clearly reciprocated. Before I met they had fooled around, but I've never known how far they had gone. Last year we went on holiday with Mark and his then girlfriend, and Pippa made sure to walk around in her skimpiest lingerie at night to give him maximum opportunity to see her. She even gave me a blow job in the living room in the middle of the day, and when I said I heard him coming back to the house, she sucked harder and faster until I came in her month. But she didn't stop, or start to put her top back on, until she had slowly swallowed it all. She seemed almost disappointed not to be caught.
A couple of months ago Pippa and I had started seeing Julia, her friend who now joined us in bed on a semi-regular basis. I'd been thinking recently it would be only fair to share her with another guy. And here seemed to be the right opportunity.
"Look, Mark. I don't know how to put this. But before I answered the door Pippa was begging to be fucked by two guys. I know you've always had a thing for her. How would you feel about lending a hand, so to speak?"
"Are you serious? Now?"
"Sure."
"Do you mean it? You want me to stick my dick in her?"
I thought about it for a second before responding. "Well you're not sticking it in me, that's for sure. And no, not really. But she says she wants it. Worst case, you'll get a hell of a blow job. After that it's up to her".
At that point Mark started taking of his shirt. "After you. And I owe you one."
"OK. But here are the ground rules; Anything other than oral is her call. Do not cum in her. We're still trying for a kid. Frankly, I'd rather you kept out of there altogether. Her ass is yours if she offers. But you have to cum on her face. That's what gets her off the most."
"Blow job. Check. Ass fucking. Check. Facial. Check." Mark had the biggest grin I'd ever seen.
