I haven't orgasmed from penetration since I was 16 but I do enjoy the feeling of size inside me, being filled, stretched, the little ache low in my belly when he's way too big and leaves me too sore to walk right when he's done. I like the sensation of weight on my back, of being controlled, of being used, the violence of him pounding my small body, knowing he can use me all day and all night or crush me like I'm nothing any time he wants. The feeling of a knot distending me and the helplessness of being tethered in place by my hole is... Just... Nnng... And I fantasize about a stable full of Shire stallions, so yeah, I do love a brutal jackhammer. But size isn't EVERYTHING and if I'm being completely honest, I'd have to say the perfect penis to me is the lovely and luscious little button between a woman's legs.
