Becca gives you a gentle squeeze - nearly bursting your rib-cage in the process - before bringing you close. Her finger and thumb press you into her chest, dipping into the valley between her tits. Whatever bra she's wearing has pressed her mammaries close together, and the immense masses of flesh clutch you just as tight as the digits: you are unable to free yourself. Instead, you begin to sweat under the overwhelming heat and pressure around you, and above all the great heartbeat of this giant.
Looking aherad, you see that Becca is examining herself in the mirror, applying something to her lips. She smacks them together before smiling down at you. "I'm almost envious. You're going to experience something... huge."
She walks from the bathroom, and while her bra is good at keeping the breasts pressed together, it still allows them to bounce as she steps. No doubt the effect is subtle and eye-catching to a regular human, but to a three-quarter inch man trapped between the tits, it is an aginising experience. Up and down you are dragged, carried by behemothic breasts whose subtle rubbing against your body chafes and grinds.
Sarah and Alfie are waiting for your host, leaning close in to each other as they smile and sip at their wine. Alfie offers the third glass to Becca, and you watch her arm stretch out to accept it.
"So," she says, turning to address the wife, "you've kissed a girl, now. Did you like it?"
"Heh," Sarah says, drawing away from her husband and draining her glass. "I think, maybe, that I did."
"You haven't even tried my cherry chapstick, yet!" Becca laughs, and the two women close in for a round two.
Alfie makes some feeble joke along the lines of 'your boyfriend don't mind it!', but you're more worried by another chest rapidly approaching. As the giants lock lips, their breasts collide with the force of a meteor. You are rocked in place, but held fast by Becca's breasts. A helpless prisoner, you watch as your captor reaches up and around, to begin undoing Sarah's dress.
"No," Sarah says, assertive and defiant, "I'll lead."
Her hand pushes back, striking Becca in the chest. Godly strength smashes into the landscape around you, fingers to either side narrowly avoiding striking you yourself. The giant falls, and as she hits the mattress, you are rocked harder than ever before, punched around by her devastating tits.
Sarah looms over you both, huge and dominant. You have had many views of this woman: as a mother, as a provider, as a monster. Now, for the first time, you see her as a sexual being, her beauty amplified beyond bearing. Your penis is certainly starting to get interested, now.
Planet Becca lurches as the woman sits up on her elbows, arms behind her to undo her own clothing. "Alfie," she purrs, "you want to join the three of us here?"
He doesn't seem to notice her slip up, and makes an interested noise from across the room. You make your own interested noise as Sarah smiles down, imbued with phenomonal feminine force. The bra snaps free, and the tits are released, allowing you to roll free from their grasp, rolling down skin just as quickly as Becca's dress slips off. Now you're able to stand, to move, to have your hands touch at the bulge in your pants.
Yes, this is a highly erotic situation, but that goddess looming above could quite easily kill you should her body come down upon the one you stand on!
