You had meant to celebrate Isabelle and Digby's birthday with them but something had come up and you couldn't make it. So you wanted to make it up to them in a fun way! So you rearranged a room for something extra special and invited them both over for a mini party.
It was low key and pretty laid back, but that was all leading up to the main event of the night. You had all discussed it prior and were all getting excited as the night went on. Both of them had their bulges pressing against their clothes as you striped some clothes off only strutting in a lacey red bra and matching panties, occasionally rubbing against their needy bulges earning whines from the both of them. When the time finally came you led the duo to the massive bed and sat down with them, both held onto one of your legs as you rubbed their bulges while their tails frantically wagged before Digby suddenly whipped out his cock along with Isabelle and stood in front of you in a presenting manner. "So between the two of us… who should do what?" Digby questioned.
They were practially asking the impossible… Isabelle's was longer while Digby's was thicker… really you couldn't go wrong regardless, so you reminded them that it was their (late) birthday so by all accounts the choice was theirs. They both gave each other intense and series looks (kinda comical considering both of them were rock hard and ready to go).
"We'll settle this the old fashioned way then." Digby declared. Isabelle nodded as they both balled up one fist raised it in the air and…
Rock!
Paper!
Scissors!
Shoot!
Isabelle choose scissors and lost, "Aw yeah! I get first choice this time." Isabelle huffed at Digby's enthusiasm, "Aw c'mon Izzy I'm not above sharing, and I'm sure they won't mind either. I just really wanna uh, hows the phrase go again? Uhm… Oh I got it I got it! Pound that pussy!" You couldn't hide your giggling very well, "Wha— H—hey now! I just forgot!" Digby pouted while Isabelle laughed along with you.
"I think I'd like a blowjob from you… Please?" You agreed and he went back on the bed and layed down flat you crawled on top of him for a moment before giving his cock a long lick and kiss at the head before you opened your mouth and started to suck him off. You fondled his balls lightly as you bobbed your head up and down earning an excited yelp from him.
Isabelle made an impatient grunt while she rubbed her cock and tapped her foot, noticing this you pulled your panties down and wiggled your hips at her. For a moment she seemed a bit unsure until you spread your ass in invitation, she gladly accepted it and got up on the bed before she got to your ass and gave it a squeeze.
She wasted no time on rimming your desperate entrance, her cock twitched while she continued her rimming and dove her tongue deeply in your ass. You moaned while sucking Digby off occasionally freeing his cock from your mouth to give him a hand job with kisses. Isabelle stroked herself furiously while freeing her tongue from your ass, precome slicking her slightly as she hotdogged your ass. Your pussy dripped desperately as you reached your spare hand to your desperate snatch while you resumed sucking Digby's cock all while Isabelle kept up the hotdogging. Digby suddenly stopped you and held your head steady while he pumped lightly, "Say uh.. would you like to try out a double dog?" He asked somewhat shakily. You freed his cock from your mouth again and agreed, feeling curious to know what it would feel like.
The twins tails both wagged in excitement as they repositioned themselves and you on the bed with Isabelle's cock pressed up against your ass while Digby gingerly teased your clit with the tip of his dick. You used one hand to spread your ass and the other for your pussy, enticing them both in Isabelle grabbed at your waist before lining herself up and pushing the tip in before stopping, "Hey Digby quit that now, I wanna know which of us feels better!" Isabelle teased. Digby muttered something before he did as instructed and began to insert himself inside you. Both were slow and steady about it filling you up with their lengths before they bottomed out just above where their knots would form, you really couldn't tell who felt better since it all heated you up so much. Isabelle rubbed your thigh, "Are you ready for the really fun part?" She quizzed in excitement. You agreed wanting to know what they could really do.
Both twins thrusted in unison, you had never felt so full in your life all while they hugged you tightly. Both had different ways of thrusting; Isabelle's length was easy to feel with how she'd thrust deeply but slowish to ensure you don't tear. Digby on the other hand had shorter and quicker thrusts while he managed to circle your clit.
You were all reaching your limits; with Digby's thrusts getting faster with his knot getting closer to locking you both. Isabelle on the other hand had thrusts that were longer with her almost pulling out before going back in, her own knot teasing your rim and almost locking in place as well. You shivered in anticipation while pleading with them to not stop, everyone was so so close; Isabelle murmured a thousand sweet nothings while Digby kept saying he was close to cumming and that he loved you desperately.
Isabelle was first, just by a bit, She pushed all in and moaned loudly as her balls were emptied into you and sealed in by the knot. Digby followed soon after, pushing all he had into place while he continued to hump as he filled you up. You came hard as they both filled you to the brim your stomach swelling up a bit as they both finally finished. Digby kissed you deeply on the lips while Isabelle kissed your neck you were overstuffed, satisfied, and quite a bit stuck. When Digby finally broke the kiss while Isabelle rubbed your stomach gently, "Weird out of pocket question, but what do you think your pups would look like?" Digby broke from his afterglow and looked nervous only for you to assure them both that you had your own precautions in place and wouldn't be having pups of any kind soon. Digby sighed in relief at that while Isabelle smirked mischievously back at Digby before nuzzling your neck letting you all settle in to the afterglow.
With no other obligations you could all simply enjoy the end of this belated birthday bash… Stuck together…
