Be a doctor, of course

Rachel, on your left side, grabbed your arm tightly as her twin sister rushed forward. Her fingers gripped you tight enough that you knew you would find purple bruises there the next day. However, you were reluctant to stop her. You had no clue what she was thinking or feeling as Megan quickly sank to her knees between yours, but you knew it must have been difficult to process the image.

You were also having some difficulty, but for different reasons. Megan was a lesbian, something you knew and had always respected. She was also the sister–the twin sister–of one of your oldest friends. Not to mention that she was medically in need. But, as self-serving as it was, you were happy to supply that need.

She and Rachel were both gorgeous, curvy women who had often appeared in your head as you found yourself jacking off. You had cum to the very thought of what Megan was inches away from more times than you could count.

Of course, in those fantasies, they were usually either naked or in some form of lace. Megan, on the other hand, was wearing a baggy band t-shirt from a Hozier concert some years ago. Her red hair fell around her shoulders in disarray as the momentum of her movement caught up with her. Pale fingers scrabbled desperately at your belt buckle in a way that you had seen before, but never wished to witness from a person you knew.

“Megan,” Rachel whispered.

The sound of her sister’s voice served to snap her, ever so slightly, back into focus. Enough for her to pause her hands so that you could take over the slightly-too-dextrous work of taking off your pants. Megan was herself enough to rear back as your bulge came into view. Her blue eyes widened at the sight, before a hand came up unbidden to cup it. She continued to eye it warily, as though it were a strange and dangerous beast, even as she hooked her fingers into your waistband.

A soft gasp escaped Rachel’s mouth as your underwear was unceremoniously jerked down to reveal your already stiff cock. You were large, a neat seven and a half inches that you proudly rounded up to eight. A few veins ran up and down your thick, ridged length. Your purple head stood proud, as though happy to preen to the women, before it disappeared in Megan’s mouth.

“Christ,” Rachel gasped as her twin immediately engulfed you.

“Yeah, same,” you muttered as the redhead’s teeth scraped you. You winced and lifted yourself up enough to finish pulling your underwear down from where Megan had impatiently left it around your thighs. She paid you mind as you moved, she simply moved her mouth with you.

You sat back as she moved up and down your length in a fervor. Certainly, it was the hottest thing you had ever witnessed. But, she was extremely bad at it. And in her state, you weren’t sure how much you could do to correct it.

Rather self-servingly, you figured you might as well try.

“Megan.”

Saliva dripped down her chin and onto her shirt as her hair began to stick to the sweat as it beaded on her forehead. Beneath her form-obscuring shirt, her massive tits swayed back and forth from her movements.

“Megan,” you said again over the sounds of her sloppily sucking you off.

The woman lowered herself until her ass was against her heels, looking up at you with watery blue eyes while your cock bulged in her mouth. The sight alone made your balls twitch.

“Be careful with your teeth. You’re hurting me.”

You were unsure of exactly how to direct her, but Rachel leaned forward.

“Try to keep your lips over your teeth. It can be tough, but with practice, your teeth will never scrape him.”

Megan looked between the two of you, lost in an addiction-fueled haze. Yet, she did seem to listen. When she bobbed her head down once more, her lips mostly covered her teeth. You hissed in pleasure at the feeling, soft, wet lips running up and down your cock. On your side, her sister held you tightly while she watched the display.

“Wow. She’s…”

Glk glk glk came the wet sounds from below as though to make Rachel’s point.

“It’s not… fuck… her.”

Your attempt at consolation was ruined by Megan’s determined mouth. She barely took a quarter of you before gagging and spluttering. By now, there was more spit on her chin and shirt than there was on your cock. One of her hands came up to pinch her nipple through the material of her shirt, causing her to moan around you. Her eyes fluttered in ecstasy at her own touch sending bolts of pleasure through you.

“Oh god,” you moaned out.

Rachel stiffened on your arm.

“Are you… are you gonna cum?”

“Mhm,” you managed out as you tossed your head back. “Getting close.”

She nodded and reached across your lap to hold her sister’s hair. She pulled it back in a ponytail, even though much of it was already coated in either sweat or spit. You could feel her own uneven breathing as her stomach pressed against your thigh. Her jacket had unzipped slightly, revealing the red flush across her own massive chest as she prepared her sister to swallow your cum.

“Ok! Uh… let me know…”

She trailed off as you nodded wordlessly. Your stomach flexed and your toes curled under the constant onslaught of Megan’s untrained mouth. Her moans of pleasure rattled up your length and seemed to almost meld with your own as you felt a powerful orgasm crash through you.

“Fuuuuuuck,” you moaned out over the sloppy wet noises of Megan desperately sucking your cock.

“Jesus. Fuck,” Rachel whispered in shock.

You couldn’t help but thrust up into Megan’s mouth as your cum began to shoot out in thick ropes. She moaned at first as the cum poured into her mouth before quickly choking on the rest. It spilled out onto her chin and shirt, before Rachel quickly reached forward and cupped her hand underneath her twin’s mouth. As Megan eagerly drank down your cum, what she choked on and coughed out pooled in Rachel’s unsteady hand.

On instinct, you reached out and grabbed the back of Megan’s head as you ground out the last drops of your cum into her mouth. When you released her, she stayed there. Her mouth no longer bobbed up and down, she simply sat there and sucked, swallowing what spilled out with satisfied moans. With a pop, she finally leaned back and pulled her mouth off of you.

Rachel was looking at your cum in her hand. She licked her lips and swallowed uneasily, fixated on it, before Megan took it and licked your seed directly out of her sister’s hand. As though it were a treat offered to a pet. Rachel swallowed heavily by your side.

Megan wiped what cum had clung to her lips and chin and sucked it off of her fingers. When she had finally exhausted all prospects of cum, she stood up on shaky legs, turned to sit on the couch, and collapsed against the cushy surface. She looked over at you, offered you a warm, if tired, smile, and promptly closed her eyes.
