Marlene's Mass [Early Access] (Patreon)

Marlene and you were looking for some privacy after the party had finally began to wind down, late into the morning. Stifling giggles and nervous excitement like two overcharged, hormone-high teenagers, you two took a brief taxi to your studio apartment.

As soon as you closed the door, you two were on each other like starving dogs on a ribeye steak. Exploring her small frame with trembling hands, you hadn't felt this energized in years. Marlene was particularly receptive to your groping her behind, which felt a lot fuller than her pants displayed at the party..

She pushed you to the couch with startling ease, and with some reluctance- disentangled and stood before you. She looked completely different- her thigh-high boots sat at her knees, the dorky sweater that hid all but her fingertips now rode up to her wriest, and once loose fitting pants looked painted on! Since the party, she must have grown at least a half foot, and filled out to match.. 

She stood, smugly reveling in your obvious gawk- "Before we continue, I've just got to stretch a little bit, I feel so pent up!"

Not sure of what she meant, you looked dumbly as she began performing calisthenic stretches, like a runner limbering up for a sprint. As she twisted and twirled, her shirt rode higher, and her pants continued to thin as each movement seemed to inflate her. For a long minute she went through a variety of motions, but you were transfixed to the increasingly jiggling mass of her rear. You watched as it was once a merely pert backside, slowly swell against her tight jeans, beyond the size of watermelons, to nearly the size of two beachballs. Besides her behind, she seemed to have grown a foot and a half since she started, her whole body proportionally larger, except for her gigantic rear. 

Inspecting herself and looking satisfied with the results, she looked at you with large, hungry eyes. She mounted over your lap, making the couch squeal- sandwiching you between two giant thighs which were each thicker than your shoulders' were wide.. leaving you claustrophobically close between couch back, and being eye-level to where her thighs meet.

"There we go, that's so much better. Now, where were we?"
