Gigantic tits can swallow a great big shark. After all they are large enough to crush a beer can when flopped down on top of it. Use it to apply 20 pounds of pressure. Fuck them with you cock knowing that it could get lost in there. Now admit you want it to get lost in these enormous honkers. Gives you a reason to fuck it harder.
To be sure when you do cum you will still want to cum again. Time over time. It is a tale as old as time Sexy BBW wants you to fuck these tits. Wrap these tits around that cock of yours. Get your cum on my lips. Down my throat. Make me sure I suck that cock every time the top of it appears above the top swell.
To be sure that pre-cum is soaking everything. Press them closer. Dip my head down farther. Lick on the tits, pre-cum, and cock all at the same time. Until finally I drain your balls with my massive jugs. Taking the biggest of sharks and milking them dry.
