"Pregnant!?!?!" The 18 year old, Arabella shouted back at the doctor. "How the...? I'm still a virgin. I think your intern here must have made a mistake! A huge mistake!"

Dr. Matt looked back at the girl who came in to the hospital emergency with nausea, crams and vomiting issues. "Well, we are very certain of the results. We can run the tests again but I can tell you they will not differ from what these results indicate."

"But I've never had a cock near that area let alone had sex with anyone." A stunned Arabella explained. "Not like my mother. She's a bit of a slut if you ask me."

In the privacy of an office, Dr. Matt and Arabella discussed options. The poor confused, just as shocked intern, Dr. David sat in the background. "I estimate you are about four to four and a half weeks based on the test and when you missed your last period."

Dr. David fiddled with something and then handed it to the senior doctor. He looked at the chart and nodded a confirmation back to his subordinate. "According to the pregnancy calculator, it happened on or around April first."

"Really?" Arabella shook her head. "Really? April first! Fucking Aprils Fool's day!"

"Yes. It seems to be then." The M.D. told her.

"But how? I'm still a virgin." Arabella asked.

"First, it is possible to be a virgin and still get pregnant. There doesn't need to be penetration but just contact with sperm. If there was some sort of transference... However, it is very unlikely. The odds of sperm remaining active enough for something like this to happen are very, very small." Dr. Matt explained. "We should also test you for any STD. Just in case."

Later, a still stunned Arabella waited at home for her mother Meredith to return. "April first? What did I do?"

She thought back to that date. She didn't even come close to any male let alone have intercourse with one. The last time she gave her boyfriend a hand job was the week before and a blow job the week before that. She never let him anywhere near her pussy at any time; not even with his mouth or hands.

"Hi Baby." Meredith barged through the front door. "Did you go to the doctor's? How did it go?"

"I'm pregnant!" Arabella unceremoniously spat out.

"Pregnant?" Her mom repeated back. "How? Bella, I thought you were saving yourself. Did you finally let Terry fuck you?"

"M..o..m! I'm still a virgin. But somehow I became pregnant. I was just trying to figure out how that might have happened." Arabella suddenly broke down and started to cry. "How... I was so careful. I..."

Meredith sat beside her daughter and surrounded her arms around Arabella. "Bella. It's okay. We can figure this out."

"I don't know, Mom. I can't figure it out." Arabella sobbed.

"When did the doctor say it happened? Are you sure you didn't do anything with Terry?" Meredith asked.

"April first. Can you believe it? F...ing April Fool's Day!" Arabella spat out. "And I didn't do anything with Terry before then or after. I just finished my period and wasn't feeling up to anything."

"Nothing? You did nothing with him? No hand jobs? No blow jobs? Did he finger you or anything like that?" Quizzed Meredith pragmatically. "You know, if he had any semen on his fingers, that could have done it."

"No, nothing." Bella tersely answered. "The last time I saw him was a couple of days before that and it was almost a week before when I jerked him off. And yes, I was careful to clean my hands afterwards. And no, I did not touch myself later. And besides, his balls are so small, he doesn't ejaculate a lot of cum."

"Well, okay. If your recollection is that good, let's go back and tell me what you did the day before and April first." Meredith said. "We'll figure this out."

Arabella started. "Well, the day before, I had classes at Uni. Got up, had my shower and went to school. Nothing happened there. Stopped at Phil's to pick up my paycheque and put it in the bank. Ate some burger at the Uni café and then came home."

"Did anything odd or strange happen?" Meredith coaxed. "Did you meet with someone? Anything?"

"No, Mom. Nothing." Bella continued. "I came home. Had another shower, then went to bed."

"I don't know, Honey. You don't get pregnant by magic." Meredith tried to suppress a chuckle. "Unless you're the Virgin Mary."

"Jeez, Mom. It's not funny." Bella snapped back. "Got up the next morning, got dressed to go work out. Just a run. Came back. Showered and went to work. Came back and went to sleep."

The smile that Meredith wore vanished as she thought about what had happened to her that day. "Uh... Bella, what did you wear when you went running?"

"Just my short sleeve top and leggings." Arabella answered. "You know I don't like to wear underwear when I run. They bunch up all the time."

"Um... Which ones?" Meredith continued.

"Leggings? I think they were on the sofa. Yeah, sofa. They were still a bit wet so I thought you might have washed them for me and they hadn't dried completely yet." Arabella explained. "I figured they would get sweaty anyways so I just pulled them on.

"The stripy, coffee cream coloured one that were there?" Meredith pointed to the sofa. "Where area were they wet?"

"Yeah, those one. I thought the crotch area was wet..." Bella told her. "... but they always take a little longer to dry in that area. Why?'

"Oh my god!" Meredith said agape. "I think I know what happened."

Shock crossed her daughters face as Meredith continued. "I remember. Jeremy came over early to help me with grocery shopping. I was wearing those leggings because they make my bum look incredible and drives Jer nuts. He pushed the cart behind me so I wiggled my ass at him to get him hot. When we stood in line to pay, he was right behind me. I could feel his hard cock press into my ass crack. He has an amazing cock; rock hard, long and fat. I wanted to fuck him right there."

"TMI, Mom. TMI!" Bella smirked.

"Yeah. Sorry, but he does have an amazing cock." Meredith looked a bit flustered. She could feel her juices start to flow between her legs. "Anyways... By the time we started driving back, I had his beautiful cock out and in my mouth. He was so rock hard, he had trouble walking when he helped me bring in the groceries."

"Really, Mom? You gave him a blow job in the car as he drove?" Arabella stated the obvious. Her own juices started to leak too. "You couldn't wait."

"Jeremy's cock is like crack. I just need it. Besides, I didn't let him cum. I had other plans." Meredith giggled. "So when I was putting some stuff in the lower cabinet, I bent over at my waist and wiggled my ass towards him. He was on his knees with his face in my crack in a millisecond and lapping me with his tongue. He's got an amazing tongue too."

"Yuck! You mean the leggings were wet from him licking you?" Shivered Arabella.

"Um... Gets worse." Meredith winced slightly. "He pulled down my legging over my bum. I didn't wear any panties either. And he went back to work between my legs. I was literally dripping. I think I came twice just from his mouth. Oh god! I can still feel it!"

"Mom! You're starting to get off topic." Arabella forcefully spoke.

"Oh gawd! I'm soaking right now!" Meredith had her hand down her jeans and was rubbing her clit. "He stood up. His fucking hard cock was between my legs and smacked against my cunt. He was sliding his shaft between my pussy lips and grabbed a condom from the cabinet where you keep them and rolled it on. Oh my fucking gawd! When he pushed it inside me, I swear I came instantly. Then he held my hips and slowly fucked me with his fat nine inches."

Arabella's hand was mimicking her mother's. She had accidently seen her mother's boyfriend's cock one day when he had fallen asleep on the couch. The shorts he wore had ridden up enough for Bella to see more than half of his tool sticking out the leg hole. She peeked inside and even his soft six inch penis looked mouth-watering.

"Oh gawd! I want his cock now!" Meredith moaned. "We moved to the sofa. My leggings pulled down over my ass and his pants around his ankles. He pushed me on my back, my leggings got in the way when he tried to put his cock back in. Instead of letting me take them off, he raised my legs and folded me in half so my knees pressed against my boobs. He didn't even use his hands to push it back into me. He started slowly at first, driving his cock into me. I think he made me cum three times before he needed to cum. Then he increased his force; fucking me harder and harder until he was slamming his hips into my ass and I swear he was hitting my cervix. My pussy was going nuts and was spasming. I think that was enough to make him start cumming too. Ooo... Oh fuck! I'm cumming! Oh...!"

Arabella started to cum too. "Yes! Oh gawd, I want a cock inside me now!"

Both women shook violently as their orgasms took control of their bodies.

Still panting, Arabella giggled. "You know, Mom. We don't do enough family stuff together anymore."

"Oh fuck! He drives me insane!" Meredith panted. "I could still feel his cock throb and pulse inside me. It felt so nice. After I recovered and let him out, he looked down at himself, then at me then at his cock. He was still rock hard and could have fucked me again which is what I thought he wanted to do. Then I noticed. The rubber had broken. I mean totally shredded. All that was left was a bit around his base."

"He came inside you?" Arabella shouted. "Wait, which rubbers did he use?"

"The ones in the far left cabinet." Meredith returned a puzzled look. "He usually brings his own."

"Those are small ones that I plan to use when Terry and I finally do it. First, they are pretty old." Arabella mouth dropped. "And Terry is not as well-endowed as Jeremey and... So how did I get pregnant?"

"Well after we recovered from our shock, we laughed and got dressed. I pulled up my leggings and could feel his cum pour out of me. Felt like a quart of cum. The whole crotch area was soaked. We had to finish getting the stuff from the car before he had to leave." Meredith explained. "Then I stripped them off to shower. I threw them on the sofa to wash but fell asleep before I could. Then I guess I just forgot about them."

"You mean... Holy shit! I'm carrying your boyfriend's baby?" The thought just struck Arabella.

"Um... Yeah." Meredith answered coyly. "Me too."
