As she swallows down your cum, her stomach bulges out, quite painfully I might add. "Maybe I might have underestimated that just a bit." she winces. As her stomach started to shrink back a little she took a look at the collar around Sam's neck, "can I take a look at this?" you nod back at her. She reaches up, pulling it off with ease, but then slips on some of the cum on the ground. She falls back, causing her to loose grip of the collar. The collar falls back with her, landing around her neck like a scarf, and it suddenly tightened up to fit. You muster up your strength and shout the best you can, "Steph, no!" She tries to pull it off, but to no avail. "I-Is it getting hotter in here or is that just me?" she says shakily, pulling off her shirt.
