>>215692 (OP)Grapple her into submission. Assuming you’re healthy adult weights (she should be less than 130lbs, you should be more than 180lbs), this will be ludicrously easy. Similar to wrestling a 13 year old boy.
The only reason this wouldn’t work is if you were chronically victim weight and she was personality maxing, or if she’s a legitimate grappler and you aren’t. In that case, you could still possibly knock her lights out with a few quick punches, but you can’t safely test it.
tl;dr
a) if your gf can wrestle and you can’t she might beat you. Deal with it. Either fix that discrepancy or decide which strapon you’d like her to use on you
b)if you gf is a hambeast cut that shit out. The porker doesn’t deserve love. Stop pretending that she does.
