Emma says, "Let's pretend I've got big boobs like, Isabella"

You girlfriend is quiet as she fucks you, she's thinking, and then she says, "Let's pretend I've got big boobs like, Isabella."

"How do we pretend you have big boobs?" you ask curious.

"Just close your eyes, John. And when you touch them, tell me how big they are. Tell me you like my big tits."

You do close your eyes, and Emma leans down so her small tits hang just slightly. Her nipples at least are large - there's nothing masculine about her body and her small breasts. You reach up with open palms and take Emma's breasts fully in your hand. You can pretend that the breasts are bigger by grabbing at her skin around the boob. You have full hand fulls of skin.

You thrust your cock up into the pussy that's riding you, as you begin, "Goddam I love these tits - these big fucking tits. I wish I could suck on them and feed off of their milk."

Emma ears eat up your words as you manhandle her breasts. She imagines herself with big tits, the kind that men ogle and drool over. She imagines herself being voluptuous like Isabella. And then she cums, her small breasts wiggle, but she imagines them large and heaving as your hands continue to fondle her through her orgasm.

Emma's body is too weak to continue riding her now, so you switch to missionary and when you're close, Emma begs you to cum on her tits, "Make them grow, John, give them your cum." You pull your slick cock out of your girlfriend and then blast your thick ropes of semen onto her modest chest.

She smiles as she takes her hands to her breasts and rubs your cum in like it's a skin care - or growth inducing - cream.
