Masuli:
I have small penis & my fantasy would be get so big, round and wide belly that it would cover + restrict access to my belly when laying on the bed.
My belly would be jutting into air + hanging onto my thighs even when laying on my bed.
sorry to hear this, probably for the best ur belly gets in the way! - all that frustration and no way to release it, oh well guess u will have to find a new hobby then!
