Yes

Elise fallows you to your room, as you enter she hugs your back and nuzzles her face into your your neck and whispers "Ive wanted that for so long". You stand there stunned, you feel Elise's soft breasts pressed into your back and the smell of her strawberry perfume, and her hard cock rubbing your ass. Wait! yes her her hard cock rubbing against your ass, normally you you liked to be the dominant one especially since your upgrade in size and sex drive. But something felt so right about it. You push back into her cock, and she pulls you tighter.

"Jesse?" Elise says in a soft voice, "yes?" you reply nervously "would you let me fuck you?, ive always wanted to fuck a guy before, and I wanna do it once before the procedure."

"yes" you reply "please" you say under your breath, she hears you and starts to nibble on your ear, "I love you Jesse" Elise whispers

You and Elise lay down on your bad, you are in the little spoon position. Elise starts to slide her smooth hands into your pants and starts rub the outside of your ass, you are rock hard, you have never felt this turned on before, in your mind your begging for her fingers. She stops "um.. hey Jesse this may sound kinda weird but.. could you put these on for me?" you look over to see Elise holding her panties and her bare rock hard cock. You hesitate as you stare at her cock knowing it would be inside you soon, before agreeing and sliding them on.

Elise's pink frilly panties felt tight on your huge monster, but you were more concered about how good the thin tight thong felt rubbing your ass, Elise started to rub your ass again "you look so cute Jesse, now I know why mom likes this kinda thing" you blush. Elise penitrates your tight ass with two lubed fingers, you moan loudly "uhh Elise slower" Elise giggles before sliding a third, she starts to prod your prostate, making you cum instantly into her frilly panties. "wow thats amazing Jesse" Elise says, you are still moaning from your deep orgasm, you have never cum this hard.

Elise starts to rub her tip onto your ass "mhmm.. ive never not had to wear a condom big bro, your ass feels so amazing" you cant wait any longer "Elise please...fuck your big brothers ass" you say in a begging way. Elise takes your order and slide about half way in as you open yourself for her. You both moan loudly.

Just as Elise enters you the door opens, your mom is standing in the doorway "Jesse?!" she gasps as she stares at your sisters cock in your ass and your cock squished in your sisters cum covered panties.
