A Threesome with my Science Lab Partners [M/F/F] Part 2

School had finally ended and I immediately jumped up out of my seat and basically sprinted out of the school to my car where I found that Sarah and Emily were already waiting for me. We all smiled at each other and piled in my car where you could cut the sexual tension with a knife, we had all been waiting. We started to pull out of the school parking lot before Emily bursted out.

"Jason I can't stop looking at your dick pic...It's just so big" she said as she turned the phone around showing off the picture of my penis.

"Yeah, Jas", Sarah added. "if I knew thats what you were packing, I would have fucked you years ago." and they both bursted out giggling.

I was kinda of frustrated with that statement but I realized she might have been implying that she was going to fuck me now so I left it as is and didn't want to jinx anything. "If I knew your tits looked that good I would have fucked you years ago too", and we giggled.

"Yeah Sarah you have great boobs...they are so big and perky" Emily added to the conversation. Sarah started to touch her chest and I could see her perfectly sized boobs jiggling in the corner of my eye while driving. "I hate my boobs, I wish they were bigger like yours Em" After she said that Sarah turned to the second row of seats in the back of my car and reached her arms to where Emily was seated. Emily replied with "No mine are too big" while Sarah started to grab Emilys tits through her shirt. "They are not" Sarah insisted. I kept peaking at my rear view mirror to find them both rubbing their hands over Emilys chest.

"Let me see them Em" I said with confidence. Without hesitation Emily obeyed and ripped off her shirt revealing her enormous boobs held tight together by her orange sports bra before she ripped it off seconds after.

"Oh my god they are so big!" Sarah exclaimed.

"Fuck, they are big" I replied back. I looked into my rear view mirror where me and Emily locked eyes. There she was staring back at me with an evil grin while her tits were dangling off her chest. "Can you play with them Daddy?" she asked lustfully as she leaned over to the middle console. I was driving with my left hand so I reached back with my right hand to grab a handful of her squishy melon of a tit. She quietly moaned when I grabbed them. I kept rubbing my hand along her chest switching back and forth between each breast.

"Fuck" I let out as I started to poke and pull around at her nipple with my finger. I noticed this excited Emily even more as her eyes rolled back and she closed them letting out a long "Mmmmmm".

I had honestly forgotten Sarah was in the front seat before I sensed her getting jealous again. "Uh hm" she cleared her throat " What about me?" she she whined out with a small pout on her face. "I'm supposed to be the teacher, remember?

With my hands still playing with Emily, Sarah leaned over the middle console for what I thought for sure would be an attempt at her sucking my dick. Instead she just rubbed her hand up and down my lap shaping out my now rock hard cock.

At this point I could already feel the precum building up at the tip of my penis. Sarah grabbed my hand from Emily's breast and pulled it onto her stomach leading up her shirt to her chest. She took off her crop top as she did this leaving nothing but her perfectly set rack bulging out of her white lace bra. She ran my hand over the top of her boob and slowly removed her bra. I continued to play with her tits the same way I did with Emily but Sarah was a lot more serious. Her tis were different than Emilys. Instead of being mushy they were firm, and her nipples poking outwards from the air conditioning vents which made them easy to play with. She knew what she was doing and she knew exactly what she wanted. Sarah pulled my hand off her chest and dragged it towards to her mouth when she began sucking on each of my fingers. This drove me absolutely nuts feeling her big soft lips around me going back and forth. It was foreshadowing for what was to come.

I glanced in my rear view again where Emily was leaned back just watching us. I could have sworn she started to rub herself until she noticed I was looking and tried to play it off. "You guys are killing me" I muffled out with a defeated voice.

"Good", Sarah said with pleasure in her voice as her lips popped off my thumb at the same time. She let go of my hand and concluded, "Lets save the rest of the fun for my house." She went to put her clothes back on, and Emily followed. I looked back over at Sarah while trying to calm myself down when I saw her texting back her boyfriend. I couldn't read the message and I didn't care what it said. I just smiled and returned my eyes back to the road.

Sarah lived about 15-20 minutes from the school. I was taking it as slow as I possibly could until they both returned their clothes back on, thats when I picked up the pace.

Sarah and Emily would continue to small talk until we pulled up to Sarahs house. I didn't say much. I was still flustered from all that happened prior and anxious for more.

I parked my car in the street in front of Sarah's house. Her parents were divorced and she lived at her Dads house. He worked late and was rarely ever home so I was never worried about him coming home to interrupt our science project.

We all walked through Sarahs front door and she led us to the left side of the house where we followed her down a hallway. Her room was at the end of the hallway on the right side. Emily was seemingly nervous as we got closer to Sarahs room. I tried to play it cool and make her feel comfortable but meanwhile I was freaking out on the inside. I had never had a threesome and a lot of questions ran through my head. Before I became lost in own worries, Sarah pointed to her bed and directed me to sit down.

I sat down and Sarah almost immediately scampered out of her room. I looked over at Emily who was standing in the corner of the room and she looked at me with a grin. She was about to say something but before she could Sarah returned back with a rolling desk chair that she'd taken from her Dads office. Sarah looked at Emily and pointed to the chair, "Okay Em, you sit here and watch us." Emily obeyed as she walked over and took a seat in the chair and positioned herself so I was the focus of attention.

Sarah had that determined look in her eyes again. She was calling the shots. She was the teacher.

"Now Em", she paused to make sure Emily was paying attention. "The first thing we have to do is tease Jas...", she said taking a slow step towards me. "And make sure his cock gets really, really hard" she said taking another step. She started to run her hands over her chest, caressing around the outside of her tits. Every slow step towards me she looked more and more determined to fuck my brains out.

Sarah was wearing tight black leggings. She slowly turned around and bent over to show off her round and jiggly ass. The same one I had envisioned pounding against my pelvis for years leading up to this moment. While still bent over facing away from, me she lowered her leggings exposing her bare ass and her ever-so inviting pussy lips. I couldn't help but notice she wasn't wearing panties but it shortly clicked in my head when I remembered it was because she soaked through them during biology. Sarah brought her leggings down to her ankles gently stepped out of them and tossed them to side.

Emily sat in her chair speechless, eager to learn and eager to get involved. She never looked away but I couldn't blame her.

Sarah stood up and turned herself around so she was facing me all while pulling her white crop top off her body and tossing it to the side with her leggings. She began playing with her tits again as she slowly got down onto both her knees. She paused in this position again for a second and looked at me. "Are you hard yet, Jason?" she asked in a cute and innocent tone. I felt the blood rush through my body and right to my face. Of course I was hard but I wanted to play along.

I managed to keep it cool again and say "Why don't you come over here and find out baby?" Sarah smiled and bit her lip still rubbing her hands throughout her body. I looked over at Emily who was still silent but her facial expression screamed how aroused she was without her saying a word at all.

Sarah leaned forward on her carpet and got on all fours showing off her beautiful tits while gravity pulled them towards the ground. I couldn't stop looking at her cleavage and how her white lace bra complimented her tan skin. The bra was barely on her now and if it dropped any lower her nipples would have popped right out. I kept staring and hoped that they would.

She crawled her way up to me and stopped between my legs while I sat on the edge of the bed. She leaned back and positioned herself facing my lap, putting her elbows on my knees. She stared into my eyes and slowly rubbed her hands up both my thighs. She reached back and unclipped her bra before it fell to my feet and her gorgeous tits sat in my lap.

Sarah locked eyes with me again while her hands worked themselves to my zipper and undid my pants. She slid my jeans to my knees and felt my cock through my boxers. She creeped her fingers in and pulled my boxers down. My cock was so hard it shot up out of my boxers like a jack-in-the-box. I saw her eyes open wider as she gazed at my towering cock above her face.

"Fuck..." she whispered in shock as she leaned her head down resting it on my right thigh for a second and watched as she gently stroked me. I wasn't sure if she did this just to admire me for herself or so that Emily could have a clear view of what she was in for. Sarah sounded frustrated now, "Fuck" she moaned out before she eagerly reached around my shaft and dragged her tongue along the base of my hard cock all the way to the head when she stopped, "Mmmm he's ready" she said with devious smile as she gently stroked my cock.

"Oh my god..." I heard Emily whisper before Sarah motioned for her to come closer. She quickly scooted her chair next to the bed.

"Okay Em, now we have to get it nice and wet like this." Sarah instructed as she reached out to grab my cock and locked her lips around me. I started to sink into the bed once the head of my penis slowly poked through her lips entered her mouth.

Sarah wasn't going slow anymore. She slurped and moaned while jerking the base of my cock with her hand. She threw her head back and forth gulping with every entry. "Em, hold my hair back" she instructed out and Emily followed quickly before Sarah returned back to work. My body grew weaker and weaker as I felt the warm sensation of her tongue gliding around me.

I looked up at Emily who was looking at me in awe as my body flailed around while Sarah suck my soul away. Sarah then gasped for air and let out a small chuckle before spitting on my cock. She jerked me up and down aggressively now while my cock slid through her hand covered in spit. "Does that feel good Jason?" she asked playfully while looking into my eyes and jerking my cock. She knew the answer already but I assured her and moaned out, "Sooo fucking good."

She smiled with pleasure after I let her know what a great job she did.

"Okay em you turn" Sarah said and pulled Emily out of her chair onto the floor. She positioned Emily between my legs just as she was. Emily looked at me with a smile and then down at my cock with an even bigger smile. She grabbed it and began to stroke me with Sarahs leftover spit and moaned out "Mmmm Daddy." She threw her head down and began sucking my dick. While doing so Sarah took the responsibility of removing Emilys leggings and leaving her in just panties.

I was getting the best of both worlds, Sarah had technique and Emily was sloppy. She was throwing her lips all over my shaft, sucking on my balls and moaning the whole time. I was fucking her mouth.

Sarah who was returning the favor and holding Emilys hair pulled her back. Emily looked at Sarah with a look of disgust and slobber all over her face. She had been rudely interrupted. Sarah reached down and grabbed Emily's buttoned up long-sleeve and ripped it over her head. Emily began to break a smile as she sat there in her orange sports bra. Sarahs hands like a magnet went to Sarah's boobs and played with them for a brief second before ripping the bra off.

Emilys tits jiggled around with every movement and I couldn't help but start to stroke myself. She whipped her head back to me after noticing how impressed I was with her. She came back to my lap and grabbed my cock out from my hands and said "No let me do it, Daddy." She placed her chin on my thigh and began to softly tap my heavy shaft to her face before throwing her mouth back on. After gaging a few times she slid her head all the way down to my balls. Her lips were touching my lap when My eyes rolled back and I glanced down at Emily who was looking at me with my entire cock shoved into her mouth. She stayed in this position for a second before bringing her head back and revealed my cock glistening from her slobber.

Do you want to ride him now, Em? Sarah asked. Emily gripped my warm hard cock and nodded her head with that devious smile again. "Just do exactly what I do" Sarah said.

Sarah wasn't teaching anymore. She wanted me to herself. She stood up straight and straddled herself onto my lap. With her right arm holding onto my back she grabbed my cock with her left hand and directioned the tip to enter her, but before she did she stopped and looked at me. She lowered her waist down towards my lap and my cock slowly disappeared inside of her. She slid up and down into my lap slowly until I grabbed her ass and sped up the pace.

"Oh my god." she cried out with the length of my cock buried inside of her.

Sarah leaned her head forward to my neck and began to bit down quivering with every thrust. My eyes wondered over at Emily who kept switching her eyes from me to down at Sarahs quivering ass slamming back on my dick.

My eyes went back to Sarah who was enjoying the ride with her mouth wide open. It didn't matter if we were dating other people. Her pussy juices were leaking out of her and dripping all over the shaft of my cock while I slide in and out of her. And that's all that mattered to us. Her tits bounced around my face until I pressed one my mouth and sucked on her nipple. She quietly moaned with pleasure between her every breathe as I went in and out of her rhythmically.

Sarahs breathes grew more heavy as she jumped violently up and down on my lap now. "Fuck!" she screamed out, "Im going to to...Im going to", She stopped and I held her down pressed onto my lap with all of me in her. Her legs started to vibrate and the vibration continued up her whole body while she whipped her head backwards. I watched as her tits rippled from the orgasm. I let loose and Sarah thrusted her hips two or three more times before sliding off of my lap. "Fuck, Jas" she tried to catch her breathe while she stumbled to feel her legs again.

"Emilys turn?" I questioned eager for more. Sarah was still looking for enough air to answer but instead nodded her head at Emily.

Emily jumped out her chair and pulled down her panties. She stood in front of me and leaned her giant tits forward to suffocate me. She straddled herself on my lap and tried to guide my still rock hard cock into her tight slit. She pushed down a little before seemingly getting stuck. Thats when I assited and pushed down a little harder before she gave in and slid herself onto me about halfway. She moaned quickly and quietly between breathes, timid to take on the length of my whole cock.

Sarah leaned over and placed her hand on Emilys ass. "Make sure you take all of it", she whispered while admiring my cock again. Emily slid down onto my lap before she letting out a loud moan now. She rode up and down slowly. Her tits began to bounce around her chest while she threw herself into me. I felt all her tight warm ridges gliding around me. Emily leaned into me and we fell back onto the bed. She leaned herself back in the air while I was still laid and her body towered in front of me. She bit her lip as her tits continued to flop around her chest. "Fuck" I exclaimed while watching her chest and began to feel the tightness start in my body.

Sarah leaned over the bed and began to hold Emilys tits together to keep them in place during her ride. Emilys moaning grew progressively louder. She stopped and threw herself off me while slapping Sarahs hands off her chest and to the side. Emily turned around facing the other way and began to squat her ass back down onto me.

Sarah was even kind enough to grab me by my shaft and direct it inside Emily this time.

Emilys plump ass clapped against my lap while her bright blonde rolled down her back. "Oh fuck, it's so big" she groaned out. Sarah reached her hand on Emily's right ass cheek and helped throw Emily onto me. Sarah looked at me and licked her lips "So big." she teased with Emily's ass pounding behind her.

It was then I thought I was about to erupt when Emily's legs started to shake. She slowed down on me as her trembling continued. "Oh my..." she cut herself short. "Fuck, Daddy Im cumming" she groaned out in relief with her ass rippling from the orgasm. Her body twitched around as she gasped for air. She continued to throw her ass back down on me before I was ready to blow.

"My turn" I cried out before throwing Emily off my lap and onto the ground. I stood up off the bed and continued to stroke myself vigorously. "Both of you come here" I muttered out before Sarah frantically crawled between my legs and Emily followed.

"Give it to me Daddy." Emily whispered before Sarah interrupted, "We have to share it."

Sarah locked her eyes into mine one last time. "Give it to us baby" She begged before grabbing my cock from my hand. She jerked me off while I looked down at both of them with their mouths wide open awaiting their reward.

"Fuck" I moaned out before blasting off into Sarahs mouth. She continued to jerk me off but switched and pointed me towards Emily's mouth so she could get her share before bringing it back to her own.

Sarah put her mouth on my relived cock and sucked off whatever was leftover before handing me to Emily who tried to lick off the scraps.

"That was way better than imagined" Emily said between licking around my cock.

"Happy to be your first", I added.

"Yeah you didn't need much teaching", Sarah said. "I watch a LOT of porn." Emily responded before we all laughed.

I was covered and sweat and felt 20lbs lighter. I pulled my pants up and looked around the room where both the girls were looking to figure out whose underwear was whose.

After we got dressed Sarah had offered Emily to stay for dinner. She went on to explain that her dad would be able to take her home later. I took this as my signal to leave and grabbed my backpack before telling them I had to be home for dinner.

The girls walked me out and Sarah opened the door for me. I walked outside and took a step before turning around. "See you girls in lab tomorrow?"

"See you there, Daddy." Sarah grinned ear to ear as she turned over to Emily and they both giggled senseless before shutting the door.

I walked back to the street and got in my car with a giant smile on my face. I threw my bag into the passenger seat and sat there for a minute reliving the events that just transpired in disbelief. I grabbed my phone and texted in the group chat, "Best science project ever." before swiping to the messages with my girlfriend to tell her we finished the project.
