Stamina Training

Slowly Morticia’s mind swam back up to consciousness, a warm tight sensation on her cock the first thing registering in her blown mind.

“Welcome back little sis,” Summer said with a smile on her face.

“Oh god it wasn’t a dream.” Morticia gasped as her still hard cock sent spikes of pleasure into her brain as Summer continued her slow grinding and bouncing on her little sisters cock.

“Nope definitely not a dream,” Summer laughed.” Can’t believe you can stay hard and cum that many times while passed out.”

“What? How long was I out for?” Morticia’s face was flush with embarrassment at the idea that she’d cum the moment her cock had been entirely sheathed in Summers pussy.

“Eh maybe 5-10 minutes. You’ve only come twice since passing out, you must’ve been really backed up huh? What’s the matter, seeing me and mom walk around naked and fucking in the living room get you hard and hot?” Summer asked with an evil grin on her face as she started bouncing her ass as she leaned forward and pressed her breasts against Morticia’s.

“Oh god you feel so gooooooood,” Morticia reached up grabbed Summers hips and started pumping her cock faster.

Summer gasped as Morticia pumped her harder and deeper, “That’s it sis make my pussy only want your monster.” Summer could feel a large orgasm rapidly approaching, lifting her chest she enveloped her little sisters head in her tits forcing a breast into Morticia’s mouth.”Suck on my tits!” Summer called out as she sped up to match Morticia’s pace.

“I’M GOING TO CUMMMMM,” Morticia’s back arched as she began slamming her cock as fast and deep as she could.

“Fuckin do it, flood my pussy with all that milk!” Summers voice matched Morticia’s in urgency and volume as the creating wave of orgasmic pleasure flooded her mind and washed over her.

Morticia buried every inch she could into Summer as her eyes rolled back and her cock flooded Summers pussy for the fourth time in less then an hour, even though she wasn’t conscious for the middle two this fourth orgasm felt just as good as the first.

“Ughhhh FUCK!!” Summer yelled as her body started shaking and spasming, her pussy clamping down on her little sisters erupting cock milking every drop of cum it could get. Collapsing on top of Morticia Summer gasped, ”I need a break ok, my pussy is so sensitive right now.”

Morticia slowly nodded and moved to allow her softening cock to slowly withdraw. Moving her older sister onto her side she put her arm around her and held Summer as she slowly came down from her latest orgasm.

“Give me a few minutes to rest and I’ll actually start teaching you some stuff k?” Summer said in between pants, that last orgasm had really shaken her.

Morticia smiled and placed her head against Summers chest. Summer pulled Morticia’s chest against hers and slowly stroked her back as they rested, “We’ll need to work on your stamina. Your cock is more than big enough to satisfy any partner but being able to put off cumming can make things better. Plus you cum buckets so we need to get cleaned up before we continue.” Summer slowly started getting up, her legs shaking she slowly got up off the bed and moved to her dresser. A small stack of towels at the top of the dresser being her objective, grabbing one for herself she grabbed several others and turned to Morticia. “Use a couple of those to clean up the wet spot and we’ll put my sheets in the wash.”

Morticia blushed as she realized how much of a mess they’d made of Summers bed, the room was flooded with the smell of sex. Wiping first herself a little she quickly cleaned up their combined fluids before she and Summer removed the sheets and went into the hallway. After placing the sheets in the washer and starting Summer took her sisters hand and led her to the bathroom.

Summer didn’t bother closing the door behind them, she didn’t mind if their mother Beth heard what they were up to and wouldn’t mind a threesome, Morticia’s cock was a lot to handle.

After setting the water to a comfortable temperature Summer turned to her little sister, put her hands on either side of her face and pressed their mouths together. Morticia felt her knees weaken with the passion of the kiss, quickly grabbing Summers hips she started reciprocating. Her efforts clumsy at first Summer gently guided Morticia on the finer points of how to kiss with passion and not get sloppy.

Turning Summer pulled her little sister into the steaming shower stall, big enough for at least four people but they stayed pressed up tightly against one another. Morticia’s cock had already hardened to its full size and was more than ready to fill Summer to overflowing again. Summer reached down and wrapped both her hands around Morticia’s shaft, “I want you to try to focus on NOT cumming ok. Most girls will cum as soon as this monster is buried inside them but that’s no excuse for you to be a quick shot so we have to train you.”

Summer moved behind her little sister pressing her breasts into Morticia’s slick upper back, reaching back Summer pumped a few squirts of body wash into her hand. “Now you’re going to try and last as long as you can k?” Summer whispered into Moriticias ear.

“What’re you going to,” Morticia’s breath left her as she felt Summers hand wrap around her cock,” Oh summer that feels so good.” Morticia could feel her next burst of cum rising as Summer slowly slid her hands up and down Morticia’s rigid cock.

“Now remember the whole point is to make you last LONGER k,” Summer said with a little laugh. “It can feel really good if you can put off cumming, just focus on trying to hold off your orgasm for as long as you can.”

Morticia tried to focus on controlling her orgasm, her throbbing cock swelling as her older sisters hands slowly stroked from her base up to her oversensitive tip. “Uhh football, school, lockers, hallways, classes, math, math class,” Morticia’s tried to focus on school as it was very boring for her but,”Jessica, Tricia, Reka.”

Images of her three crushes flooded her lust addled mind, Jessica in class naked except for revealing lace lingerie standing out like a beacon against her pale skin. Tricia standing at the front of the class in a black thong and high heels working out a problem on the board. Reka sitting at her desk in a bright red string bikini that top barely covered her nipples and the bottom dug in between her delectable pussy lips pressing against her hard clit.

“OHHHH FUCK,” Morticia’s eyes rolled back in her head and her hips surged forward as her cock erupted coating the wall of the shower with cum.

Summer smiled to herself as Morticia’s orgasm erupted out of her, putting her arms around her little sister and holding her up she patiently waited for Morticia’s to come down.

Morticia gently moaned as she slowly came back, “Sorry Summer I really tried to last longer.”

Summer leaned forward and kissed Morticia on the cheek,”you aren’t going to have pornstar stamina right away. Who was it at school that made you cum like that?” Summer asked with a smile.
