Requested by Monika2934: Y/N plays a prank on Peter in which she gives him Viagra without him realising. The fact that he's hard makes him very horny and so Y/N helps him out.

*Please note: as the request suggests, this one-shot contains Y/N giving Peter a drug without his consent. I want to emphasis that me writing this is NOT me condoning it, of course you should NEVER give anyone any type of drug unless they have fully consented to having it. However, also do please remember that this is just an imagine, it's not real and so please don't take it too seriously and comment things like "this is really fucked up" or anything. I know that some people do not agree with some of the topics that I write about, that is absolutely fine, but I'd rather people just not read those chapters than comment about how wrong the subject matter is. That being said, feel free not to read it, and if you are going to read it, enjoy. Thank you :)*

I crept along the hallway, the pill bottle in my hand as I headed into mine and Peter's shared room in the Avengers' Tower. I opened the door and looked around cautiously to make sure that it was empty before creeping in and shutting the door. Peter and I had met a year ago, when I had joined the team aged twenty. We had hit it off immediately, and he had asked me out within a month. Since then, we'd not only been happy in a relationship...but had been regularly pranking each other too. It had started with the basics of him putting my hand in warm water whilst I slept, and me loosening the screws in his chair so that it would break when he sat down on it, and was currently ended with him dunking a bucket of ice cold water onto my head. Meaning that it was my turn to retaliate, and I knew exactly what to do. I smirked and bit my lip as I went to grab his glass of water from the bedside table. Peter had hurt his knee on our last mission and so was on painkillers, meaning that I knew for a fact that he'd drink the glass of water in order to down his pills. Which is why this was so perfect. I opened the pill bottle in my hand and tipped out one of the pills of Viagra that I'd been given by a friend for this exact purpose, the pill landing on the palm of my hand. I put it on the table and started to hammer the bottle against it, crushing the pill into dust so that my plan would work. I brushed it into the glass of water, the powder disappearing into the liquid as it dissolved.

"Your move, Parker." I chuckled to myself, knowing that all I had to do now was wait as I crept out of our bedroom again.

I sat in the living room with Nat, Tony and Steve, all of us watching TV as we relaxed on one of our rare days off. I looked up and tried not to smirk as Peter walked into the room, my boyfriend's body clad in a tank top and sweatpants as he walked in. I was very much looking forward to the Viagra kicking in, especially as I had no doubt that he'd want me to help him with his impending problem.

"Hey, guys." Peter smiled as he slumped down onto the sofa next to me and curled his arm around my waist.

"How's your knee doing, kid?" Tony asked.

"Yeah, it's okay. Just took my meds again, so the pain isn't too bad right now." He nodded. I smirked and looked down, making Peter look at me.

"You okay there, babe?" He chuckled.

"Yeah, I'm fine. Just glad that you're not in pain anymore." I lied with a shrug. He narrowed his eyes at me, his brain clearly somewhat sceptical of me.

"Mhm. I'm definitely not suspicious of you right now." He scoffed and shook his head. I smiled and leant up to peck his lips, him only just returning the kiss as I rested my head against his chest. He sighed and chuckled as we both turned back to the TV, a smile on my lips as I rested my head and hand on his chest. This was going to be good.

Peter and I cuddled on the sofa, the pair of us still sat with Tony, Nat and Steve as we watched TV. It had been about half an hour since Peter had taken his pills, and so I was expecting to see the effects of my pranks soon enough. As if on cue, I started to see movement on Peter's lap. I flicked my eyes down to his crotch, a smirk curling onto my lips again as I watched the growing tent appear in his sweatpants.

"What the fuck?" Peter mumbled as he quickly removed his arm from around me to grab a cushion instead. I looked up at him, my boyfriend's eyes wide and his cheeks burning red as he quickly grabbed one of the sofa cushions and put it over his lap.

"You okay there, Pete?" Natasha chuckled. I smirked and bit my lip as Peter's eyes widened further.

"Y-yeah, I'm fine, I, um...I need the bathroom." He nodded as he shot up from the sofa, his hand continuing to hold the cushion against his crotch as he rushed towards our bedroom.

"What's up with him?" Steve scoffed.

"No idea. But I think that I should check on him." I sighed in false worry as I stood up.

"Yeah, make sure that he's okay." Tony nodded. I returned it as I turned to head down the hallway.

"I will." I smirked to myself, my heart starting to speed up in anticipation of what was to come as I headed to our bedroom. I opened the door and slipped into the room before looking at Peter.

"You okay?" I chuckled as I saw him sat on the bed, his fingers holding the waistband of his sweatpants open as he looked at his clearly hard dick.

"No, I'm not, I'm fully hard and I don't know why. I wasn't even turned on, it literally just happened." He scoffed as he stood up.

"Gee, I wonder what did happen." I shrugged and tried not to smirk. Peter looked at me.

"I-what? What did you do, babe?" He gulped.

"I may or may not...have put crushed Viagra into your water." I admitted with a giggle. His eyes widened, his mouth falling open as he looked at me.

"Oh...my god. I didn't think that you had it in you, oh my fucking god." He scoffed and shook his head, making me laugh and bite my lip as he gave me a slow clap.

"I know that you didn't think that I had it in me, which is why I needed to prove you wrong." I nodded as I put my hands on his chest, his arms curling around my waist to pull me closer.

"Well, you did prove me wrong, it's a very good prank. Now, how do you feel about helping me out with my...problem?" He smirked.

"Why do you think that I did it?" I teased, making his smirk widen as he leant down and smashed our lips together. I returned the kiss immediately, my hands curling around his face and pulling at the hairs at the nape of his neck as his hands gripped my waist. The kiss immediately got heated, Peter's tongue slipping into my mouth and starting to dominate mine as we started to make out.

"God, you're so fucking hot, baby." he mumbled as he broke the kiss and moved his lips down to my neck. I breathed out at the feeling, my eyes fluttering shut and my mouth hanging open as he started to leave more open-mouthed and nippy kisses on my skin. Time to take over, I thought as I pushed him away from me. The force of my push made Peter fall back onto our bed, my boyfriend looking at me with a smirk as I straddled his lap.

"Fuck, the things you do to me, angel." He shook his head, making me return his smirk as I leant down and smashed our lips together again. He returned the kiss, his hands moving to hold my thighs as I pushed him back onto the bed. I broke the kiss and started to kiss down his neck. He breathed out and tilted his head to give me more access as I gently nipped and bit at his skin.

"Fuck, babe." He mumbled as I kissed down to his collarbone and tugged at the bottom of his t-shirt. He got the hint and sat up to pull the garment off, my lips pulling away from his skin as he did. He lay back down underneath me, my lips making contact with the space in between his pecs as I kissed down his body. He looked down at me as I did, his mouth hanging open and his hand going down to my hair as I kissed down his abs and to the waistband of his sweatpants.

"Angel, shit, please do something." He choked.

"Don't worry, Pete. I'll look after you." I smirked, making him moan at my words as I started to pull his sweatpants and boxers down in one sweep. His rock-hard dick sprung free and slapped against his stomach, the sight alone enough to make the space in between my legs dampen even more. I wrapped my fingers around his shaft, making my boyfriend suck in a breath as he looked at me.

"Baby, please." He begged. I smirked and bit my lip, Peter begging turning me on immensely as I started to move my hand up and down him. I started to work his dick, his head falling back against the pillow as moans radiated from his lips.

"Jesus, angel, fuck." He moaned as I continued to work him with my hand. I leant down and gently wrapped my lips around the head of his dick, making him gasp and arch his back off of the bed.

"Fuck, shit, babe!" he cried out as his hand landed on my head and gently started to bunch my hair into a ponytail. I took the action as encouragement, my head starting to sink down on him as I sucked him off.

"Baby, Jesus." He moaned. I smirked against his dick, my lips massaging the sides of his shaft as my tongue swirled around his helmet. Moans radiated from my boyfriend's lips, his body squirming underneath me in an attempt to deal with the pleasure that he was feeling as I worked his dick with my mouth. I raised my other hand and started to massage his balls, more moans spilling his lips as his grip on my hair tightened.

"Shit, angel, stop, I'm going to cum if you keep going like that." He choked as he used his hand on my hair to gently my mouth away from him.

"I better make you cum another way then, huh." I teased, making him smirk and shake his head as he leant his arm back to his bedside table to grab a condom whilst I stood from the bed. I quickly pulled my underwear and jeans down as he opened the condom, my body straddling his again as he rolled the rubber onto his dick. He looked at me.

"You ready, baby?" he asked.

"More than." I smirked before sinking down onto him. Small sighs and moans left our lips as I sat down fully on him, my eyes fluttering shut at the feeling of being completely filled by him.

"Oh my god, you feel so good." Peter choked as his hands gripped my hips.

"So do you." I smirked, making him return it as I placed my hands on his chest to steady myself as I lifted myself up. I started to ride him, my pussy engulfing his dick and then letting it go with every movement. Moans left both of our lips as I sunk down onto him, his hands gripping my waist and my fingernails gently scraping down his abs as I fucked him.

"Fuck, angel, just like that." Peter moaned, his mouth hanging open and his eyes glued to the space in between my legs as my pussy absorbed his dick. I smirked and bit my lip, my eyes fluttering shut and my head falling back as the knot in my stomach built with every time that I rose and fell onto him. My orgasm continued to build up inside of me, my ass and thighs now slapping against Peter's skin as I rode him as fast and hard as I could. Our moans bounced off of the walls and mixed with the sound of our skin slapping together to create the perfect symphony, the smell of sex all around us as our bodies got more caked in sweat than they already were. Peter was filling me up perfectly with each sink down back onto him, his tip hitting my g-spot with every rise and fall of my ass.

"Babe, I don't know how much longer I'll last." Peter grunted, his eyes still glued to my pussy as he watched it engulf his dick.

"I'm close too, Pete, it's okay." I nodded. He returned it and sat up underneath me, making me cry out at the new angle as he wrapped his arms around me and pulled me into his chest before smashing our lips together. I returned the kiss without hesitation, our lips, teeth and tongues clashing feverishly as we made out again. His nails gently scratched the skin of my back, our moans going into each other's mouths as I also tugged at the hair at the nape of his neck. He thrusted into me harshly, my hips also sinking down to meet his thrusts as I felt the knot explode in my stomach.

"Peter, shit." I choked against his lips, my eyes squeezing shut and my head falling back as my orgasm hit me harshly. The waves of pleasure washed through me, my legs shaking on either side of Peter's lap and my body jolting in his arms as I let the feeling take over.

"Fuck, baby." He moaned into my neck, his teeth gently scraping my skin and his arms pulling me as far into his body as I would go as he came too. We panted heavily, Peter's hot breath warming the skin of my neck up as we both came down from the incredible highs.

"Wow." He breathed, making me giggle and bite my lip as he placed a few more gentle kisses on my neck before loosening his grip on me and allowing me to climb off of him.

"That was amazing." I sighed in bliss as I lay back on our bed and he binned the condom.

"It really was. Best prank that you've ever played on me by far." He nodded, making me smirk and bite my lip as he lay down next to me and curled his arm around my waist so that I was pulled into his body and my head and hand were on his chest. I looked up at him.

"We calling it a tie for now, then?" I asked. He bit his lip and looked down at me.

"Yeah. Tie. Well done." He smiled and raised his closed fist. I chuckled and gave him a fist bump before resting my head back against his chest, a sigh of bliss leaving my lips as we started to relax and cuddle.
