Girlfriend’s Twin Sister Caught me Masturbating

The first time I dated a woman with a twin I was always a bit thrown off whenever her sister was around. As almost identical twins, there was obviously no question whether I was attracted to both sisters. They were both around 5’7”, blonde, sensually curvy with bubbly smiles, and fun personalities. In my own narcissism I also assumed that because of how similar they were that the sister would also be attracted to me. The morning I finally confirmed that was quite the thrill.

My girlfriend at the time’s name was Lisa, her twin’s name was Becca. They lived together in a downtown apartment in a large city. We would routinely go out on the town together and end the night back at their place.

One such night was around St Patty’s Day. We went out and got after it, aggressively. Lots of beers, Irish car bombs, shots of Jameson, the works. Now both girls could hold their liquor, but Becca was probably a little stouter of a drinker than Lisa and on this night it showed. By around midnight I was taking Lisa back to the apartment so she could pass out. No harm, no foul, I was drunk myself, and other than the accompanying horniness I had held out hope of resolving, it was probably better for me to head to bed with Lisa and go to sleep.

In our drunken stupor no action took place and Lisa unfortunately had to stagger to an early shift at her job the next morning. I had no such obligation other than the unyielding morning wood I awoke to. As every man of a certain age knows, there are few better hangover cures than a thorough self-love session. Whether Becca was still in the apartment never crossed my mind, even if she was home, she wouldn’t have any reason to pop into her sister’s room, right?

With both heads throbbing I went to work rubbing the one that would stifle the pain in the other. I was going to take my time, including snapping off a quick pic to send to Lisa to let her know what she was missing in her own bed. A series of lip bite and yearning emojis in response let me know my manhood had the desired effect. Blushing with confidence I leaned back into her bed and worked myself over until I was leaking with precum. The covers were completely off now, and I figured Lisa would enjoy a status update.

I fired off another snap and before the response could come in suddenly her bedroom door burst open. Becca had come rushing in and was in the middle of asking if Lisa had stolen her favorite hoody. She stopped mid-sentence as we locked eyes, both stunned at what we were witnessing.

My phone buzzed as Lisa responded to me but I made no motion to grab it, paralyzed with anxious arousal. I definitely should NOT be showing my cock to my girlfriend’s sister. She definitely should not be looking at it. Yet, we both stood transfixed, Becca stood in the doorway in just a sports bra and biker shorts looking at me like I should say something.

“I, uh, did not know you were still home,” I said sheepishly as I started to reach for the covers.

“Clearly,” she said with a wry smile. She saw me attempting to cover up and cut me off.

“Wait. You seem to be in the middle of something.”

“Um, well, I, uh, yeah you could say that,” I stammered, right hand clutching the covers I had started to pull closer, left hand resting on my thigh where I had moved it abruptly when she burst in.

She took a few steps into the room, coming closer to the bed. “Well, you don’t have to stop on my account. Just pretend I’m not here, I’ll just look around for that hoody.”

I was floored and did not know what to do. She peeked into Lisa’s closest and gave a token effort to look through her stuff while I tried to cover myself back up. I couldn’t help but check out her ass as she bent over in the closet. I felt there was a zero percent chance my erection was going anywhere and pulled the covers up a little further, as if the tent I was now pitching was any less obvious.

When she turned back around, she looked at me and laughed.

“You really don’t need to cover back up, do you think it’s the first time I’ve seen your cock? Lisa shows me all the time. She likes to make me jealous.”

At this point I was blushing profusely. Obviously, I had contemplated this possibility, fantasized about it even, but it was different to hear it directly from Becca’s mouth. I didn’t know what to say or do. Becca was considerably more decisive.

Before I knew it she was standing at the end of the bed, grabbing two fistfuls of the covers. She yanked them off and threw them on the ground, exposing me once again. She sat on the edge of the bed looking right at my throbbing member.

“Now, weren’t you in the middle of something?”

Without thinking my left hand found the base of my manhood and I slowly began to stroke myself once again. Her blue eyes were locked onto mine until she very deliberately began to stare at my cock.

“That’s a good boy,” she said with that evil grin.

I moaned audibly at this, and I was again blushing profusely, as she bragged about knowing all about what I liked. All of the sudden my sensitivity was ratcheted up tenfold. Every stroke felt like it could put me over the edge. I started leaking heavily, immediately.

She bit her lip as she watched me, encouraging me to keep going, telling me I was bigger in person. She was playing me like a puppet, I was helpless, so hard, all the blood flow going to the wrong head for making rational decisions.

“I’m getting close,” I half croaked, half moaned as the precum was acting as an additional lubricant, my heavy balls tightening with impending release.

“Mmm be a good boy and cum for me.”

It looked and sounded just like Lisa. But it was her sister. Which made it both wrong and hotter at the same time. I erupted. The first rope hit my upper lip and chin. The next few covered my hairy chest and abdomen. I moaned wildly as I pumped myself, the release felt intoxicating, and my moans turned to whimpers as I milked the last drops out.

Becca watched the explosion with a satisfied smile on her face. The shock of what just happened hit me immediately and I didn’t know what to do or say now, laying there covered in my own cum.

“Fuck,” was all I could muster and Becca laughed as she crawled towards me, my chest heaving, cum literally dripping from my entire body. Leaning down I watched in pure shock as her pouty lips pursed to give my still mostly rigid cock a kiss. I gasped at her touch, the sensitivity and the surprise of everything sending shivers through my body.

She then swirled her tongue around the head, scooping some lingering cum up with practiced expertise. She looked me dead in the eyes and said, “You do taste good. There’s more where that came from, right?”
