Fun at Home?

"How about..." Sophie circled her finger on my now very muscular chest "... we properly celebrate at home. Just us two. And we enjoy whatever we love most..."
"I love to, babe..." I looked down at the definitely most kinky girl I ever met, who now with her much increased bust size looked even more alluring. Sexy, kinky girls with big tits were like my only weakness, and god knows I wanted to. "... but you know I got to work today." Sophia however just stared at me with a mischievous smile. Before I could ask what she was up to, my phone rung, it was my boss. Rolling my eyes I entwined myself from my girlfriend and picked it up.

"Hey John..." my boss started. I was working at a local hardware store, and if he called that usually meant over-time. "Been checking the schedule today and it seems like you still have a few extra hours to clear. So since there isn't much to do today anyways, would it be ok if you take today and tomorrow off?"
"Uh... yeah." I responded, completely confused what was going on "I guess I can do that." I couldn't remember when my boss every gave me a day off at all, and now he was calling right on time to... I frowned when I realized what was going on. A glance at Sophia was all the confirmation I needed, seeing her standing there with that beaming smile, like she perfectly knew what just happened.
"Ok... see you next week then." I finished the call and hung up.

"Would you believe it, my boss just gave me two days off..." I said with a smirk and gave her a kiss.
"What a perfectly fitting coincidence." she purred and started to really lean into the kissing.
"This is going to be one hard day." I mumbled while my hands run over her near perfect body. Slightly smaller, slim to almost athletic, and now sporting DDs on her frame. It was like a wish coming true. Soon enough her hands were running down my improved body as well, till she eventually begun the usual routine of giving me a sensual hand-job to get me started.
"I just came, babe." I explained the lack of erection she was probably expecting at that point. She looked at me disappointed as she remembered for a moment, but then that devilish smile returned. Suddenly I felt a tingle down in my dick, and like someone just gave me an injection of the blue pill, I felt briefly light-headed as my dick rose upwards at record speed. Seconds later it came into parking position between us, throbbing so hard I had a tough time focusing my thoughts.

"What did you do?" I asked, while my dick stood between us, throbbing so hard like it was trying to set a new record.
"We both do what we love today..." Sophia oozed sex into my ear "... and what I love to do today involves a lot of this." She squeezed my dick and gave it a few good rubs, sending my into a roller-coaster of pleasure and desire for a moment. "So to ease things for you, rock-hard is now the default." She giggled while I was still busy ordering my thoughts.
"Did you just turn my dick into a bar of steel for all eternity?!" I asked slightly shocked.
"Nah, just till Monday." she leaned down a little, and I could feel her breath on the tip of my throbbing erection. "Can't have the other girls get any wrong ideas here." I was about to protest, but then I felt her lips wrap around my now very needy shaft, and I kinda forgot what I was about to say.

Sophie wasn't necessarily an expert at blow-jobs, but she enjoyed to do it slow and sensually, and my dick was more than ready to blow another load. And she loved to see me twitch and moan, while she had full control over me and my "joy-stick" as she called it. So I stood there, moaning, groaning, twitching, as despite my recent orgasm she managed to get me to the edge again in no time. She kept me there for a few minutes, which **** me to sit down on the toilet lid eventually when my legs couldn't hold it anymore, and there she finished me off. Unable to hold back, I just let go and under loud moans sprayed my cum regardless of where it would land. Midway I realized this wasn't my normal volume anymore either, as I kept sending massive load after load, but then I also hadn't been a muscular hunk this morning, and my girlfriend didn't have huge tits. When it was finally over I looked at the probably hottest sight I had in a while: My girl kneeling before me, staring at me satisfied, with cum all over her face and tits like someone splashed a full cup of it against her, and between my still throbbing 10 inches that she had blessed me with.

"Breakfast?" she asked with a wide grin.
"Be there in a moment..." I returned, panting and exhausted. She left me as I was, giving me a nice jiggle with her ass on the way out, and when I looked back I learned that all the juice I blasted off had somehow disappeared. What didn't disappear though was my raging boner. That dick still stood there like I didn't just cum twice, throbbing like Sophia enjoyed me most, and I could clearly feel like there wasn't even the option anymore for it to go down. I probed it, squeezed it, moved it, and eventually realized that fully erect was now literally the only state my cock could be in.
"That bitch..." I laughed. I knew why she did it, and I knew I wouldn't regret it, but this also meant my head wouldn't come out of that fog of arousal anytime soon. Ever since we experimented with Cialis back then, and she had my dick so jumpy that she needed to just flash her tits a little to get me started, watching me in this highly aroused and **** state had become one of her kinks. We did that a few more times, until I grew too concerned with the side-effects of those pills, much to her disappointment. But whatever she could do now was not only much more powerful, but also - probably - didn't come with any side-effects. I realized that this would indeed be a hard extended weekend...
