“May I?” she gestured towards my dick with her hand.
“By all means,” I said, suppressing a grin. “It’s been a while since you’ve played with a cock, hasn’t it?”
Madison nodded. “Too long.”
She reached over and grabbed the lube. She blushed a little as she uncapped the top and squirted some lube onto my dick, which at this point was throbbing and genuinely in dire need of attention. Madison recapped the bottle and placed in on the edge of the bathtub next to me.
After taking a shaky breath, Madison slowly gripped the base of my cock with both hands. She began to slide her hands up my cock, her thumbs tracing over my balls before running up the underside of my shaft while the rest of her fingers wrapped around my cock itself. She gently massaged the lubricant all over my swollen cock, savoring the feeling of having a hard dick in her hands for the first time in a while. Once my dick was thoroughly coated, she traced the fingertips of her left out slowly down my shaft. From there, she took my balls into her hand and began to gently massage them. The entire time, my toes were curling and I was moaning loudly. She really knew how to work a cock.
“I love listening to you moan,” Madison whispered softly as she began to stroke my shaft with her right hand. Her left hand continued to play with my balls. She gripped my shaft more firmly and slid her hand up and down.
Normally I’m not a huge fan of handjobs, but getting a handjob from my girlfriend’s sister when my dick was covered in lube? Count me in. I mean, Madison was basically just worshipping my sex with her hands.
“I love watching you play with my cock,” I said in response, whimpering as she slowly began to increase her speed. My eyes followed her hand as it slid up and down my shaft. As she stroked me faster, her tits began to bounce in rhythm with her pumping my cock. Her nipples were hard, and I’m sure her pussy was nice and wet.
“Please don’t stop, Madison,” I groaned. She was stroking me quickly now; the sound of her hand pumping up and down my cock filled the room. From the look on her face, I could tell she was enjoying this at least as much as I was.
“I can’t wait to feel your cock throb in my hands as you come,” she said softly. She bit her lip and eyed my swollen cockhead, waiting eagerly for her reward.
That just about pushed me over the edge. “You’re gonna make me come, Madison,” I groaned. “Oh my God, please don’t stop! Fuck!”
“Come for me, baby,” Madison cooed as she stroked me. “I want this big cock to shoot all over me. Don’t you wanna cum all over your girlfriend’s little sister?”
“Yes!” I cried. “Oh fuck, I’m gonna come! Oh my God, fuck yes. Don’t stop, Madison!”
I braced myself against the edge of the tub as best I could. My toes curled hard as the first rope of cum erupted out of my cock, landing on Madison’s cheek.
“Oh my fucking God,” I grunted as I shot another two ropes onto her tits. The first landed on her right boob just above her nipple while the other was a bullseye, hitting her left nipple directly.
Madison’s hand flew up and down my cock, coaxing as much cum and as much pleasure from it as she could. Her left hand was playing my balls, massaging them and milking as much cum from them as possible. My orgasm ended with me crying out as another three ropes erupted out of my cockhead and landed on her face. As I finally stopped ejaculating, she let go of my cock.
“Holy shit,” she said. She stood up to look at herself in the mirror. I got a great view of her ass as she stood up and walked away from me. Her buttcheeks were big and round; honestly she really did have a booty that rivaled Ashley’s.
I was breathing hard. “Thank you,” I said.
“You’re welcome,” she looked at me, grinning. “I think I look hot covered in your cum. What do you think?”
“You look very hot,” I smiled.
She sighed happily. “Your cock was throbbing like crazy while you came,” she said. “It was so sexy. Like feeling it in my hands pulse and throb while you ejaculated on me — that was so fucking hot.”
“It tends to do that,” I laughed. “I’m glad you enjoyed it.” She must have really enjoyed stroking me off. She sounded like the happiest person on the planet right now.
“Dude, I’ll jerk you off whenever you want,” she said. “Like that was fucking great.”
“Oh really?” I smirked. “How about right now?”
“Could you actually go again already?” she asked, raising an eyebrow. “You came a lot. I’d be surprised if those balls of yours weren’t empty. But then again, Ashley loves to tell me how many times she’ll make you come in a night.” The fact that we were having this conversation while she stood naked, covered in my semen was certainly helping me be ready to go again.
“Maybe, I don’t know,” I said, laughing. “I was just curious if you really meant you’d jerk me off ‘whenever I wanted.’”
“Oh,” Madison said. She shrugged. “Well, if you are still horny then I’ll happily get you off again.”
I thought for a moment. “I mean, it’s hard not to be horny when you’re standing there in front of me naked, covered in my cum.”
She walked back over to where I was sitting and got back down on her knees. “So I should jerk you off again then?” She took my soft penis and balls into her hands. She gently massaged my balls and just sort of held my soft cock in her hand. It was slowly but surely getting harder.
I shrugged. “If you wanna make me come, then make me come. I am still horny.”
“I’d love to make you come,” she grinned.
KNOCK KNOCK
Madison turned white and shot up. I was a little startled, but the only other person that uses this bathroom is Ashley so I wasn’t particularly worried. I nudged Madison to respond.
“Hello?” Madison said. “I’m in here!”
“I know,” Ashley called through the door. She twisted the handle twice to point out that the door was locked and she couldn’t come in. “Unlock the door!”
Madison breathed what I figured was a sigh of relief. She walked over to the door and twisted the lock. Ashley heard the click and turned the handle, walking in and quickly shutting the door behind her. She made sure to relock it.
“Wow,” she said, looking at Madison. Her tits and face were still coated with the results of my last orgasm.
“What?” Madison said, mimicking the tone Ashley used that night when Ashley had flashed Madison in the shower. This was quite the role reversal.
“Nothing,” Ashley grinned. “You look hot covered in jizz like that, though. Just a bit more on your stomach and face and the look would be perfect.”
“Thanks,” Madison giggled.
“Though if it were me, I’d want some inside me too,” Ashley said.
Madison just laughed and rolled her eyes.
I was still sitting on the edge of the bathtub. My cock was back to being fully hard again. The fact that Ashley saw her naked sister covered in my come with easily enough for me to blast through the “refractory period.”
“You’re still hard?” Ashley smirked, looking at me.
“I think he just got another boner,” Madison giggled. “He was still pretty soft before you came in. Am I not good enough for you anymore, Brian?” she teased.
“Honestly, it’s just really hot that you’re naked in front of Ashley,” I said. “Especially since you’re covered in my cum.”
