I pulled out and Cherys flopped onto her side, panting softly with a smile on her face. I moved back over and with careful aim and slow tenderness, slid my rock hard cock back into Danielle's dilated hole. Danielle didn‘t cum again. She was simply a warm, happy body clamping her own ass muscles rhythmically with my thrusts, loosening up for me to plunge in and then squeezing me on the way back out, as if to coax out my load.

She was rewarded a short time later, when I groaned, “Oh, Danielle..

“FLUL my ass, David. Fill up your sister's butthole with your creamy jism."

That was all it took before I slammed forward a final time and let loose, spunking every drop into my sister's rectal cavity.

I finished spurting, and then Danielle's legs gave out before I could pull back, She collapsed to the bed, pulling me down with her. For a minute, I just lay with my cock still embedded in her asshole, kissing the back of her neck and her cheek while she mumbled happily.

I flopped over onto my back then as Cherys scooted over, the two of us sandwiching Danielle between us. The girls kissed lovingly while Cherys stroked her girlfriend's back. And then Danielle flipped her head around to look at me.

“We are definitely doing that again." week

Kevin and Jen looked at me with bemused expressions. I was still watching Danielle and Cherys heading back to their car to go home.

Kevin was the first to say, “You are SUCH a man-slut."

If only he knew. The girls and I had visited Kevin and Jen for dinner, in part to announce the pregnancy. My friends hadn't seen Cherys in a couple of months and the questions had immediately begun when she'd arrived with a slight belly bump on her normally svelte figure.

Jen had a knowing smile but Kevin just about flipped out when Cherys explained, “David is the father." Even after the girls informed them that I was just a sperm donor and it was really Cherys and Danielle's baby, Kevin was still looking at me like I was some sort of sex god for scoring with Cherys. If he knew I'd been banging Danielle as well, he might have blown a gasket.

Well, everyone has their secrets. In fact, Amber was the only one who knew for certain that I'd slept with both Cherys and Danielle those years ago. E-Beth or Diane might suspect, but I was pretty sure they didn't know for sure. But after the way Danielle had been looking at me during dinner, I wondered if my friends had caught on anyways.

The girls had gone home, but I was staying to visit with my friends. For a few minutes after we sat back down and Kevin made his ‘man-slut' comment, everything was quiet as Kevin and Jen kind of looked at me funny, trying to process everything. Relaxed, I just sipped my Coke and waited them out.

I only started to get nervous when Jen the psychologist asked, “How is Danielle handling this?"

“Huh?" I was trying to be noncommittal, not overreading her question.

“You slept with her girlfriend, David. From the way Cherys looks, you're STILL sleeping with her girlfriend. Is she jealous of you?"

I looked at my drink and blushed.

“I don't think so,“ I stated confidently.

“You sure?" Kevin put in.

“Danielle was giving you some weird looks. Like she was happy with the baby and all, but a little uncomfortable with the whole situation."

I shrugged. To my mind, Danielle was probably uncomfortable having to pretend like she wasn't sleeping with me as well.

"We've had a lot of talks about that. They're the couple. They're the parents, although they'll let me be a part of the kid's life. But I'm just the third wheel. I provided the sperm, and..." My eyebrows went up as a slightly guilty expression spread across my face.

"And well... Cherys' pregnancy can get her a little horny sometimes. I only too happy to help out."

“Dude, I KNEW it!" Kevin crowed.

“Man-slut!"
