After less than 3 months of dating, Sheldon and Penelope had grown intimate as had Matt and MJ.

Sheldon's phobia of germs was nearly nonexistent except in hospitals and laboratories where germs were being tested.

Sheldon was over at Penelope's one night with her sitting in his lap. They were both in their underwear while some serious petting was taking place. (He had three spare outfits over at her condo.)

Sheldon rubbed his thumb over her string bikini, feeling gathering moisture between her legs as he kissed along her carotid artery. Sheldon's boxers rubbed against his crown as did Penelope's fine ass.

The pressure from the rubbing coupled with the bikini's texture was a delicious feeling for Penelope. She mewled as her level of pleasure rose. She kept shifting her ass in Sheldon's lap, feeling his thick erection pressing against her ass.

His left hand fondled Penelope's bare breasts, causing her nipples to turn into pebbles.

Penelope craned her head around to lay an ever so passionately deep kiss on him. "I need you." Her green bikini was already soaked through.

Sheldon no longer felt the need to wait to be fully intimate. He wanted to bury his cock in her wet feminine heat. (He wasn't a virgin like some thought.)

Ready for the next step, Sheldon turned his girlfriend around in his lap. "Wrap your legs around me," he instructed before he stood up. A groan escaped him as her crotch came in contact with his groin.

Penelope kissed Sheldon's shoulders as he carried her to the stairs then up. When they reached the upper level, Penelope tightened her grip on his waist while making out. A groan caught in his throat at the pressure from his groin from her crotch.

As Penelope slid down his body, her breasts brushed his chest and her legs took her boxers off. His very erect cock sprang up to slap his lower stomach.

Sheldon inserted his thumbs to draw off her bikini then pushed her over, following her down on the bed. He braced himself above her using his more muscular arms. He took a rosy hard nipple into his mouth, suckling it while he pinched her other nipple.

"Please," Penelope begged, wanting to feel him in her.

Sheldon slipped a hand down to his cock to guide it to her wet entrance. His crown bumped against her clitoris, causing her back to arch.

"Sheldon," Penelope whimpered, desperate now.

"Patience, my sweet Penelope," Sheldon whispered as he pushed in.

Penelope's breath caught at the sensation. Her hips jerked up, bringing him closer to her womb. Her hands went to grip his hips as he laid a kiss at the soft spot below her ear.

A swift thrust home started the age-old dance that pagans revered. Sheldon was slow to withdraw, but his thrusts were just the opposite. Their hips met with great collaboration.

The loving couple was evenly matched. His thrusts hit her G-Spot with precision while her slick and tight channel caressed his engorged length.

As Sheldon felt his orgasm approaching, he used his thumb to brush her clitoris in light strokes, not wanting to deny her the same pleasure of an intense orgasm.

Penelope's deep inhalations signaled her pleasure from each stroke of his thumb. Her back arched as her climax was nearing the peak.

Sheldon wrapped his arms around her to feel her skin rubbing his.

Fireworks exploded behind her eyelids as the dam of pleasure burst. Her breath was coming out rapidly.

The world fell away as Penelope's hot walls enclosed his engorged cock. His seed squirted out as he climaxed. (Penelope was on the pill for keeping her period regular.)
