In my, albeit pretty poor defense, it was supposed to just be a blowjob. Fine, I'll start at the beginning.
"So you're telling me, some random girl is going to come to the security building, wait in the supply closet and suck my cock, in exchange for some perfectly legal edibles?" I said, repeating what my friend had asked me.
"Maybe legal in the state but her Dad would kick her ass if she got caught trying to bring them into campus, getting them from you, she's already past the checkpoints, you yourself know how much of an asshole Steve is, he loves busting people," she replied.
"And you're fine with me getting head from some random girl?"
"Marcus, we're not a couple, we have nasty, wonderful sex and we're free to see other people. I want you to tell me about it when we have sex on Friday."
"Fine but this is weird, even for you Tara. So many other ways she can get it."
"So you'll do it?"
"Yes."
Tara squealed and kissed me on the lips.
"Wednesday, 9pm, make sure the hallway lights are out too."
Campus security had its perks, I'd been in the Army and blew out my knee on some unorthodox training exercise and when I was done with rehab I sued and won a settlement that set me up for life. Helped that my Dad was the lawyer and managed to find so many things wrong and they paid out just to shut me up. I didn't care, I enjoyed the relatively easy life and the hot young coeds that threw themselves at me on a regular basis and didn't care that my job had no real future, at least not with the company I was with. The day finally arrived and I let myself into the supply closet right at 9pm, bag of edibles in my hand.
Dim light from a cell phone led me to a chair and I sat down as instructed and waited until she turned her phone off. She then put a cushion at my feet and pulled my legs apart then got to work undoing my pants. She pulled my pants and boxers down to my ankles then fondled my balls.
"Do you have it?" she whispered.
"3 packets," I replied, also whispering.
I put the bag of edibles at my feet then sat back as she leaned forward and took my cock in her mouth. I gasped instantly, I half expected a quick, half handjob, half blowjob then she'd disappear but once she sucked me into her mouth I was in bliss. She sucked the tip as she gently fondled my balls then kissed and licked my shaft as I hardened, she really knew how to make it feel great and my breathing got heavier as she went on. She didn't seem to be in any rush to get me off either, the way she sucked me I knew if she wanted to she'd have me cumming in minutes but she took her time, savoring my cock like it was a prize.
"Your cock is beautiful, can we do more?" she whispered.
"What do you mean?" I whispered back.
I soon got my answer, after a brief pause I felt her push my legs closed and she straddled me. She held my cock and put me at the entrance of her pussy.
"This is what I mean, I want this inside me, I'm clean and on the pill," she said, her breathing heavier too.
I answered by gently pulling her down onto my cock. She kept the lead though and put her hands on my shoulders as she thrusted onto my cock until she had all 8 inches of me inside her. She mumbled a 'oh fuck yes' as she began to fuck me, her thighs slapping against mine as she enjoyed my cock. I initially had my hand on her waist but she pulled off her shirt and put my hands up to her breasts, I took the hint and was fondling them, enjoying the tight globes and her swollen nipples in the darkness. When I took one of her nipples into my mouth and sucked she gasped then a few seconds later she was cumming, gasping 'yes yes yes' as she took as much of me into her as she could. I didn't last too much longer and pushed up from the chair as my cock exploded, spraying my hot seed into my mystery lover's pussy. When we'd both come down, she pulled her nipple from my mouth and kissed me passionately.
"That, was the best blowjob I've ever given," she said quietly.
"It's certainly the best one I've ever received," I replied, forgetting to be quiet.
The girl had been rocking back and forward, enjoying my softening cock still inside her but when I spoke she froze for a second then leaped off me. I was blinded for a second when she turned the light on and we started at each other.
"M... Marcus? Wh... what the fuck? What the fuck are you doing here?!" said my sister Clara, her eyes wide.
I was staring at her chest, her breasts really were as beautiful as they felt in my hand and mouth then reality snapped in.
"I... it was just supposed to be a blowjob, I didn't know it was you!" I replied.
Clara, still staring at me, slowly covered herself up.
"Wh.. what did we just do," she said, almost in a trance.
"Turn the light off," I said, worried we would get caught.
I pulled my pants up and straightened up my shirt, Clara used the light from her cellphone to find her panties and pulled them on. She put the edibles in her bag and put her bag on her shoulder. I didn't know what to do, Clara came and held me in the dark, touched my face and kissed me again then left the room quietly. I quickly turned the light on, made sure the chair and cushion was all I had to remove then left the room. A few hours later, once my shift had ended, I got a text from Clara.
'Can I come and see you?' was all she sent.
'Of course.' I replied.
Clara arrived maybe ten minutes later, she had changed into sweatpants and a loose t-shirt and her hair was tied in a ponytail. I opened the door for her, she walked in without saying anything and pulled me by the hand to the couch. She sat facing me, her pretty face not showing any emotion at all.
"I want you to promise me something," she said.
"Okay, what," I replied.
"Promise you didn't know it was going to be me in there."
"I promise Clara, I swear on my life."
"How do you know Tara?"
"We're uh, friends with benefits I guess."
"She's not answering my calls or texts, she knew and set us up, did you say anything to her, how does she know we're related?"
"I have no idea, I don't really talk about you, we barely talk at all to be honest. Ah, fuck."
"What?"
"The picture I have as my screensaver, she must have spotted it, our last year at the lake."
