A pump bottom is a chromosomal XY âmaleâ who prefers lying in the supine position with erect phallus facing upward. âHeâ necessitates the sexual partner (a chromosomal XX âfemaleâ) to be vaginally mounted on âhe/hisâ fully engorged penis, participating in a rigorous sexual act until âhe/himâ reaches orgasm. Simultaneous orgasm is an added benefit.
A Pump Bottom is truly fulfilled when engaging with a compatible âPower Top.â
While on the couch, Marie got on top of Bobby to have sex. As a Pump Bottom, Bobby planted both of his feet firmly on the floor to engage his entire body to thrust into Marie ever so harder and harder until they both climaxed.
