I woke up in a daze the next morning. It took me a few minutes, but then I remembered all of the events that occurred last night and my cock started getting hard.
Knowing dad was still on his trip and Natalie was still at school, I figured I'd just walk downstairs naked and see if Mom could give me a hand.
When I got to the foot of the stairs I couldn't see Mom anywhere. I walked over to the kitchen to look for her but couldn't find her there so I turned around to check if she was in the basement office.
Just as I was about to head down to the basement I ran into my sister Natalie.
"Hey Mike...holy shit, your cock is huge!!" my sister Natalie screamed.
"Oh shit!" I said trying to cover myself up, "What are you doing here? Where's Mom?"
"She's down in the basement, I just came over to grab a few things. Why are you naked, with a boner, and why are you looking for Mom?"
"No reason...Uh, I'm gonna go upstairs and put something decent on." I said as I darted back up the stairs.
I went to my room and put on a pair of sweatpants and headed back downstairs.
When I got downstairs Mom and Natalie were in the kitchen talking.
"Morning honey" Mom said, while looking away from Natalie.
I went over to mom and gave her a kiss on the cheek while trying to avoid Natalie's glare.
I grabbed a cup of coffee and sat down at the kitchen table while my mom and sister continued to talk. They talked for about 10 more minutes before Natalie announced that she had to head back to school to study. She gave mom a kiss, looked at me, gave me a wink, and then said goodbye before she headed out the door.
The minute I heard her car leave, I hopped up and headed towards mom. She was still standing in the kitchen by the sink with her coffee in her hand. I came up behind her and pressed my erection into the crevice between her ass cheeks.
"Oooh honey, someone's excited. What made you so excited this morning?" Mom said coyly.
"Oh, I don't know Mom, maybe the fact that we're home alone and extremely horny" I replied
"Hold on honey, before we do anything, can you please drop by the pharmacy and get the Plan B pill? Then I promise we can fuck all day long. I still have a lot to teach you."
"Alright. Just let me get my dick to go down then I'll head over there. Shouldn't take me too long, then we can get back to what we were doing yesterday, right Mom?"
"Yes honey, now go get changed and put some proper pants on. I can easily see the outline of your cock in those pants. You wouldn't want your Aunt to get all hot and bothered now, would you?"
Ah, that's right. My Aunt usually worked weekends at the local pharmacy. That's why Mom initially asked me to buy the morning after pill. She didn't want to run into her sister and have her become suspicious. My Aunt knew my parents were trying for a baby, and she also knew that my dad was out of town, so Mom coming in and buying a morning after pill may have caused her to ask a few too many questions.
We figured it'd be easier for me to go, get the pill, and just pretend it was for some girl I was seeing. That way, there would be less questions asked.
After changing into some more conservative clothing, I grabbed my keys and headed to the pharmacy. When I got to the pharmacy my phone went off. Mom sent me a text to remind me to also buy some condoms so we could continue fucking without the worry of her getting pregnant.
Just like clockwork, I ran into my Aunt immediately as I stepped foot into the pharmacy.
"Hey Michael! What a surprise to see you here today. How can I help you this morning?"
My Aunt Jessica was drop dead gorgeous. She was a spitting image of my mother. Almost more so than any of my sisters. The only difference between my Mom and Aunt was that my Aunt Jessica had black hair and was a couple inches taller than my Mom. She still had those sexy wide hips and thick ass just like my mother did. Her breasts were a little bigger than my mothers, but like I said, I didn't care much for breasts...I was a pure "ass man".
I walked up to the counter and gestured for my Aunt to come closer so that I wouldn't have to be too loud.
"Um...Aunt Jessica, I am looking for the morning after pill..."
"Oooh Mikey, did you get some little girl pregnant?"
"Hopefully not! I just want to be safe. So, do you guys sell it or not?"
"Yes, we have it here, but I think I'm going to have to speak with your mother about this. Does she know what you're getting up to?"
Trying not to rouse any suspicion, I quickly replied "No. Please Aunt Jessica, don't tell her! Please can we keep this between the two of us? I promise I'll be more careful."
"Okay. I'll give you the benefit of the doubt this time, but you really need to be more careful. Maybe you should consider using condoms if the girl is not on any birth control."
That's right! I had almost forgotten that mom told me to get some condoms too.
"Yes, Aunt Jessica, I was planning on grabbing some today too."
"Alright, well if that's the case, come with me I'll show you where we keep them." She said before grabbing my hand and guiding me through the aisles towards the condoms. My cock started to swell as I followed closely behind my Aunt's thick ass.
"Do you know which kind you want Michael?"
"Ah, yes. I need the...Magnums." I paused for effect. I was feeling a little bold and wanted to see if I could get a reaction out of my Aunt.
I think my Aunt was taken aback by my comment because she just looked back at me like I'd spoken some foreign language.
"Magnums? Oh, those are over here. Come on I'll show you. How many do you need?" She said, flustered.
I quickly tried to estimate how many times me and Mom could fuck in the next 3 weeks before dad came back.
"Uh, I think 30 or 40 should be fine."
She looked up at me with this look of bewilderment, "That's quite a lot of condoms Mikey. Sounds like you have yourself a girlfriend, huh?" She said with a wink.
