Becky is incredibly turned on by your size

By: Cheese111

"Can I?" Becky looks over to Kim with puppy eyes.

"Of course, he's your boyfriend." Your sister responds with a chuckle. It was a little humiliating to see your opinion being skipped in whatever your girlfriend had planned next, but your gut feeling told you it was probably going to be pleasant. You held up your arms and let her grab you. Her grip was gentle, though it was disorienting to be moved up to her face as fast as she did. Soon you were eye to eye with Becky. She gave you a broad, suggestive smile before puckering up. You were unable to do anything as she pressed her lips on you. Only your top half was sticking out from her hand and she smooched all of it at once. It was nice, but utterly overwhelming.

"Mwah. You're the cutest little boyfriend I've ever had." She cooed, walking over to Kim's bed and taking a seat on it. You were a twentieth of her size, but that only made you more attractive to her. You'd kissed before, but you weren't prepared for what she had in mind next. "Hold on tight, Will." She mumbled as she pulled down the collar of her shirt and stuffed you between her breasts. It was warm, a little sweaty but above all insanely comfortable. Each of her soft mounds was the size of a car and together they smothered most of your body. Her bra kept things somewhat in place as her large body shifted and moved around you. You picked up on the rustling of cloth, but were too distracted by your new position to do much else. When she fished you out of her cleavage you were in for a shock.

"Mmm... Just thinking about you is making me wet..." She said, dropping any hint of restraint. Kim was content to sit back and idly stroke herself as your girlfriend had taken off all her clothes, only her panties and bra remaining. You were staring at the evidence of her statement, her panties showing a large wet patch. A creeping doubt began to crawl up your back. Was she still drawn to you as a person, or did the idea of using you as a toy send her into sexual overdrive?

"Fuck me, Will." She pulled open her panties with her free hand and dropped you in. You were instantly enveloped in a world of intense smell. Her pussy was soaking wet and so was the fabric behind you. Even with your best efforts you weren't sure what you could accomplish here. But this was a once in a lifetime opportunity and you'll be damned if you let it go to waste. You reach up to play with her clit, your erection standing proud and ready. Your hands find their mark and the enormous body of Becky shudders with pleasure. Her labia were man-sized compared to you and your cock was easily lost in their folds. It drove you to climax almost instantly, giving out a tiny, shameful moan. That was mere seconds you lasted. But more worryingly, you weren't sure if Becky even noticed you had fucked her.

A large finger provided the answer. It pressed against your back and began to push you into the soft pussy. While pleasant at first, it soon dawned on you that much like your sister's oversized cock, this love tunnel was now large enough to hold you completely. No sooner had the thought passed your mind or a heavy push rammed you halfway into her birth canal. Like an awakening beast the walls around you squeezed and pulled, eager to consume the rest of you to satisfy her needs.

"Becky! Wait!" You cried out as her finger found its way to your head and pushed you in completely. You were shoved into another sweltering organic tunnel. At least it was your girlfriend this time, but the oppressive squeezing made it no less terrifying. The pace quickened as you felt her orgasm approach. You held your breath with what little stale, musk-soaked air was there as she bathed you in her release.

Kim stroked herself faster and harder, seeing Becky use Will as a sex toy. Almost in unison with her she came, spraying a long rope of cum across the room. Damn, she should've put on a condom or something to hold the mess. But this was so awesome she didn't want to miss a second of the action.

When the wild excitement turned to pleasant afterglow Becky sat back, looking at the puddle in front of her drenched panties. It quickly dawned on her that something was missing in there. In spite of the flood created by her orgasm, Will hadn't come out.

"He's still in there..." She said, her eyes widening at the realization.

"Yeah, but I'm sure he's okay with that. And he should be more than capable of surviving in there too." Kim tried to reassure her whilst stroking her still rock-hard erection.
