the dirty lotus
when the man gets a stiff one while sitting up then pulls his knees into his chest, hold his feet with his hands so the bottoms of his feet touch each other and the top of his feet face the opposite direction from each other, thus resembling a lotus. The women does the same so she fits on top of the man. Then the man spread lube all over his chest then they both lean back and the man puts his hands on the women and proceeds to thrust her up and down his cock.
"Dude why didn't you call me back last night!?"

"Oh sorry dude I was doing the dirty lotus with my girlfriend last night!" "She was screaming so loud all whole night, then my landlord came by this morning and gave me a high five."
