I couldn’t stop moaning on his nerdy friend’s cock while my bf just watched [f18] [cuckold]

I’m 18, first year in college, and I’ve been with my 20 yr old bf for a while. We’ve been trying new things in bed, and when he bought me my first dildo, I didn’t expect it to flip a switch in me. I loved the way it stretched me, the way my body struggled to take it all, and soon I found myself craving something bigger every single time. My bf knew. He could see how wild I got for the toy, how much louder I moaned when it was buried inside me compared to when he was.

One night after we finished, he admitted something that made me soak instantly. He told me his friend, this nerdy guy he gamed with all the time, was ridiculously hung. Shy, quiet, glasses, but packing something huge. I laughed and teased him, asking if he was jealous, but I couldn’t stop thinking about it. The idea of taking something massive, with my boyfriend watching, turned me on so badly I couldn’t sleep.

We invited him over a few days later. It was supposed to be casual, just video games, drinks, and joking around. I wore little shorts and a cropped top on purpose, and I caught the way his friend kept sneaking looks. My boyfriend noticed too but didn’t say a word. After a couple drinks, I got bold. I sat closer to his friend, brushing my thigh against his, leaning in to whisper, letting my top ride up so he saw my stomach. My boyfriend’s eyes were locked on me the whole time.

At some point, I straddled his friend’s lap like it was a joke. He froze, stiff and awkward, until I kissed him. That broke him. He kissed me back hard, his hands gripping my waist, and I felt the thick outline of his cock pressing against me. My boyfriend just sat there, stroking himself already, watching me grind on his friend. By the time I tugged his sweatpants down, I nearly moaned just from seeing it. He was huge, long and thick, heavy in my hand. I looked back at my boyfriend like, “are you sure?” and the way he just nodded while jerking himself off made me wetter than I’d ever been.

I lined him up and slowly sank down, my pussy stretching around the biggest cock I’ve ever taken. The stretch made me gasp, made me whimper, and I had to grip his shoulders just to handle the way it pushed into me. My boyfriend was right there, watching my pussy swallow his friend’s cock inch by inch until I was stuffed full. I could barely breathe. It felt so deep, so much more than anything I’d taken before.

I started bouncing, grinding, riding him while his thick shaft spread me wide open. My moans filled the room, wet sounds echoing every time I slammed down on him. His friend grabbed my ass, squeezing and helping me move faster, fucking up into me with so much force I was shaking. My boyfriend sat just a few feet away, eyes glued to the way I was taking it, his hand stroking his smaller cock as he watched me lose myself.

The more I rode, the messier I got. I was dripping all over him, soaking his cock and thighs, leaving wet spots on the cushions. He was stretching me so perfectly I couldn’t hold back, I screamed into his neck as I came hard, pussy clenching around him, milking his cock for every inch. He didn’t stop, though. He kept thrusting up into me, pounding me through it, fucking me even deeper while I was still shaking.

When he finally groaned and spilled inside me, I felt it flood me, hot and thick, filling me in a way I’d only dreamed of. I collapsed against his chest, panting, still twitching on his cock, cum leaking out around his shaft. My boyfriend’s breathing was heavy too, his hand a blur on his cock as he came just from watching me get ruined.

I looked back at him with a fuckedout smile and whispered, “This is what I needed.” And he didn’t argue. He just kept staring at my pussy, stuffed and dripping with his friend’s load, knowing he couldn’t give me what I craved but letting me take it anyway.
