Ashly Rabbit VR is in the doctor's office with her boyfriend, both eager for a quick fix to make her already perky tits grow massive overnight. The doctor hands her a small vial of experimental growth serum. Ashly downs the liquid in one gulp and within seconds her chest swells dramatically, bra straps straining as her natural B-cups balloon into heavy, overflowing DD-to-E size huge tits. Boyfriend's jaw drops, cock instantly tenting his jeans at the sight of her new massive cleavage bouncing with every breath; even the doctor shifts uncomfortably, bulge obvious as arousal hits hard. The room turns electric. Ashly drops to her knees between them, freeing both thick cocks at once. She takes boyfriend's shaft first, sucking deep while stroking the doctor's throbbing dick, then switches. She bends over doggystyle for the boyfriend to slam balls-deep into her dripping shaved pussy from behind, pounding hard as her massive new tits swing wildly beneath her. The doctor steps in front, feeding his cock back into her eager mouth so she can suck him while getting railed. She climbs on top next for cowgirl, straddling the doctor reverse, sinking down onto his thick shaft, riding fierce and grinding her clit against his base while her heavy tits bounce in boyfriend's face. Doctor grips her hips, thrusting upward deep until he unloads thick ropes of hot doctor cum straight into her spasming cunt, filling her up until it leaks out messy around his shaft. Ashly keeps grinding slow, milking every drop while boyfriend steps closer, stroking faster until he blasts a final thick cumshot across her bouncing tits and open mouth. That is the best breast expansion threesome fuck she has ever had. Read less
